- Motor Oil Viscosity Warning What happens if you use the wrong oil viscosity in your car Using the wrong motor oil viscosity can cause serious problems like premature wear, a check engine light, and even camshaft damage.
What happens if oil viscosity is too low?
If you use too low a viscosity oil metal-to-metal contact occurs, poor sealing and increased oil consumption. If you use too high, the fluid friction increases resulting in reduced energy efficiency, higher operating temperatures, and hard starting – particularly at cold temperatures.
What is the risk of using oil with a high viscosity?
For instance, too much viscosity can cause churning losses and excessive heat generation from molecular friction. It can also impede lubricant movement and flow to lubricant-hungry surfaces. One of the most famous disadvantages of too much viscosity is high energy consumption.
Does oil viscosity really matter?
It’s best to use the viscosity recommended in your owner’s manual, but a slightly thicker oil or thinner oil likely While it’s best to use what’s recommended in your owner’s manual, inadvertently using a viscosity one grade higher or lower than what’s recommended generally poses no long-term harm.
What does the oil viscosity number indicate?
The lower the number, the less the oil thickens in cold weather. The numbers after the “XW” indicate viscosity at 100 degrees Celsius and represent the oil’s resistance to thinning at high temperatures. For instance, oil with a 5W-30 grade thickens less than oil with a 10W-30 grade in cold weather.
What happens if I put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w- 40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
Does motor oil lose its viscosity?
Motor oil is a lubricant. Your internal combustion engine is a complex machine, and like all machines, it has moving parts. And like all moving parts, the parts of your engine wear down over time as they move against each other. Over time, your oil can also lose viscosity.
Can I use 10w30 instead of 5w30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Will thicker oil damage my engine?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.
What happens if you put 5w30 instead of 5w20?
What Will Happen If You Put 5w30 Instead Of 5w20? Using 5W-30 instead of 5W-20, you risk damaging your car’s engine because the internal engine components work with 5W-20 motor oil. 5W-20 and 5W-30 motor oil both have the same winter rating. Higher viscosity numbers suggest a heavier oil that flows slower.
Can I use 10W 40 instead of 10W30?
10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.
What does 10W30 mean?
That’s why you see two numbers on most oils. For Example: 10W30. This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot. Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly.
Can I put 10W40 instead of 5W20?
In a 5W20 engine. You could use a 0W20 oil (I use 0W20 oil) in cold weather and it would be Ok by Ford. (they will not say it is good, but they will still honor the warranty..) But 10W40 is way off, and I bet they would be not so happy over any engine problems if they found 10W40 in a failed engine.
Is higher viscosity oil better?
Thin, low viscosity oils flow easier to protect engine parts at cold temperature. Thick, high viscosity oils are typically better at maintaining film strength to protect engines at high temperatures.
How do you read motor oil viscosity?
In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil’s cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine’s normal operating temperature.
Can I use 10w30 instead of 5w20?
Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.
Causes of Low Oil Pressure in Engines
It is one of the most critical criteria in an engine that the oil pressure be maintained at the proper level. When your vehicle’s oil pressure indicator illuminates or the pressure gauge displays a value that is lower than usual, it might indicate a serious problem. Unfortunately, you won’t be able to tell if the problem is significant until you switch off your engine, so the best course of action is to just turn it off. This article will discuss the probable reasons of low engine oil pressure as well as the most efficient strategies to rectify the situation in order to offer a better knowledge of engine oil pressure.
Reasons for Low Oil Pressure
There are a variety of reasons why the oil pressure in an engine might be low. When the pressure gauge detects low oil pressure, be aware that it may be a genuine low oil pressure indication or it may simply be an incorrect readout. However, understanding some of the most frequent reasons is beneficial in any scenario.
1. Not Enough Oil in the Engine
If the proper quantity of oil is supplied during an oil change, the oil may be consumed excessively as a result of evaporation, combustion caused by worn piston rings, and leaks through the seals or the oil plug, among other factors. The engine’s oil consumption rises as it gets older, so checking the oil level and topping it up may be a simple remedy. If, on the other hand, leaks are visible outside of the engine or there are oil drips on the floor, the leaking component should be repaired as quickly as possible to avoid further damage.
It is necessary to do an overhaul when the engine consumes one quart of oil every 1,000-2,000 miles.
Therefore, ensure that you follow the recommended oil change intervals and that you check the oil level on a regular basis.
2. Too High or Low Viscosity
If the proper quantity of oil is supplied during an oil change, the oil may be consumed excessively as a result of evaporation, combustion caused by worn piston rings, and leaks through the seals or the oil plug, among other things. The engine’s oil consumption rises as it ages, so checking the oil level and topping it up may be a simple remedy. The leaking component should be repaired as soon as possible if oil leaks can be seen outside of the engine or there are oil drips on the ground. The oil consumption of an aged engine increases.
Even though the engine is not particularly old, if the oil change period is overextended, the oil level may be dangerously low.
3. Apparent Low Pressure
In diesel engines, the pressure gauge often displays real-time pressure in pounds per square inch (psi) or bar pressure (bars). Some lubricant manufacturers provide lubricants with a lower viscosity than the SAE grade, but which are still within the acceptable range. A lower viscosity allows for increased fluidity in lubrication systems, but it may also result in a lower pressure reading on the pressure gauge due to the lower pressure.
If the pressure is within the usual range, there is no need to be concerned about anything. Some lubricants may create higher pressures than others, and you may notice this during testing.
4. Engine Wear
Low pressure might be caused by damaged engine bearings if the oil level on the dipstick is between ‘add’ and ‘full,’ especially if the engine has a high mileage and the oil level is between ‘add’ and ‘full.’ As a result of excessive wear, the initial flow restriction is reduced, which results in a decrease in pressure. If this is the case, it is probable that the engine will need to be repaired or completely replaced.
5. Defective Oil Pressure Gauge
If the oil pressure warning light has on, but you have verified that the oil level is right and that the engine is operating normally with no odd noises or excessive temperatures, the problem may be caused by a faulty sensor device in the engine. It is possible that you may want to get the oil pressure checked with a gauge. If the pressure is normal, the oil pressure sensor should be replaced without more ado. However, if the warning light or low gauge reading persists after the sensor has been replaced, the problem is most likely due to a faulty oil pump.
6. Pump Wear
If the oil level on the dipstick is between ‘add’ and ‘full,’ yet the engine is making a lot of noise, it’s possible that the oil pump is worn. Due to internal leaks, a worn pump is unable to create the necessary pressure to function properly. Stopping the engine until the problem is resolved is a good idea. It will be necessary to replace the pump.
7. Plugged Filter
Even if the oil level on the dipstick is between ‘add’ and ‘full,’ if the engine is making noise, it is possible that the oil pump is worn. The internal leaks of a worn pump prevent it from generating the appropriate pressure. Stopping the engine until the problem is resolved is a good practice. There will be a need to replace the pump in this situation.
Reducing the Risk of Low Oil Pressure
You lessen the likelihood of experiencing low oil pressure in your engine, be sure to replace the oil and filter at the recommended intervals. As a bonus, choose high-quality lubricants that meet the American Petroleum Institute (API) quality standards and have the proper viscosity grade and quality level mentioned in the engine or automobile handbook. Check the oil level in your engine on a regular basis, and look for leaks in your engine (as well as your garage floor). Additionally, keep an eye out for blue smoke coming from the exhaust, which is particularly common with high-mileage engines.
Oil analysis will be the most effective predictive/proactive technique for fleets in order to evaluate the condition of the oil and the gear in question.
Why Oil Pressure Is Important
The lubrication system of an engine is composed mostly of the pump, the oil filter, the lubrication lines, and the hardware. The resistance that the oil must overcome in the lines in order to reach the lubricated components is the source of the pressure in the system. The lubricant is forced through the system by means of a pump. In the design stage of an engine, the pump is constructed to provide the pressure and flow necessary to allow the lubricant to circulate to the farthest-reaching component.
Moreover, it indicates that there is probably not enough lubrication going through the system.
It is possible for an engine to fail in a matter of hours or even minutes, depending on the severity of the condition. The repair might also be expensive, given that the majority of the engine would need to be replaced.
The viscosity of the oil has an effect on the oil pressure. Suppose you were to spill oil over an inclined surface, the oil would flow downhill as a result of the gravitational pull. The higher the viscosity of the oil, the more slowly it will flow. Viscosity may be described as the resistance to flow of a liquid or gas. The viscosity of the lubricant changes with temperature, lowering as the temperature rises and rising when the temperature drops, as seen in the graph. As a result, the viscosity of engine oil will be affected by the ambient temperature of the engine at startup as well as the engine’s usual operating temperature.
- To perform the first experiment, an oil solution is allowed to flow through a capillary tube while timing how long it takes for the oil to flow from one spot to another.
- The higher the viscosity of the mixture, the more difficult it will be to stir it.
- Tests are carried out at specific temperatures in order to produce consistent findings.
- These criteria, which are based on the measuring techniques outlined above, make it easier to choose the proper lubricant for your engine.
- As an alternative, it designates a viscosity range that includes a minimum and maximum limit.
- Lubricant viscosity and pumpability at low starting temperatures are indicated by the letter ‘W’ in the SAE classification.
What Causes Low Oil Pressure (& How To Fix It)
When a warning light illuminates on your dashboard, it might indicate that your engine is experiencing low oil pressure. This could indicate a significant problem. For an engine to operate at peak performance, it is critical to use the proper oil and maintain the proper quantity of oil and oil pressure. It just takes a few minutes for an engine to be completely destroyed if the pressure is allowed to drop too far. You should get aware with what oil pressure is, why it is essential, some of the typical reasons of low oil pressure problems, and what to do in the event of an emergency if you want to avoid incurring a large repair fee and an even greater headache later on.
Importance of Oil Pressure
A well-maintained oil pressure is one of the most significant components in keeping an engine operating smoothly and for a long period of time. Engines are sophisticated pieces of machinery that have a lot of weight to pull – both metaphorically and physically. The presence of oil in an engine ensures that all of the moving components are properly lubricated and are able to perform at their best. When oil is being circulated through an engine, pressures begin to rise. It is because of this pressure that the oil is able to reach all of its destinations and maintain its flow.
Friction, warping, seals cracking, and a variety of other problems are caused as a result.
If left unaddressed, oil-related issues can cause significant harm to your vehicle’s performance.
As soon as the warning light illuminates to signal that there is an issue with the pressure, pull over to the side of the road immediately. The following are 5 of the most prevalent reasons of low oil pressure in your engine to give you a better sense of what the problem could be:
5 Causes of Low Oil Pressure
Low oil pressure can be caused by a variety of factors, some of which are more visible than others. If your oil warning light is illuminated and you wish to examine your engine yourself, the following information should be of assistance:
1. Oil Level Is Too Low
One of the most prevalent causes of low oil pressure is a reduction in oil level below the minimum dipstick line, which can occur for a variety of reasons. Despite the fact that you may have just had your oil changed, this can happen at any moment. Engines get increasingly oil-consuming as time goes on. This is caused by a variety of factors such as piston rings wearing out and seals leaking. Alternatively, you may discover that you genuinely have an oil leak. As a result, depending on the age and condition of your car, you may notice a greater decrease in oil pressure.
What to do – Check the oil level on your car.
Make sure there are no leaks by watching for oil drips on the floor and keeping track of how many miles you have left until you need to top up.
2. The Viscosity of the Oil Is Too High or Too Low
A measure of how smoothly lubricating oil flows around an engine at a particular temperature is known as viscosity. If the viscosity of the oil in your engine is incorrect, this might manifest itself as low oil pressure. Oil with a high viscosity will normally have increased resistance, whereas oil with a low viscosity will have the opposite effect. Oils with lower viscosities are typically used in colder conditions, but in the summer, when temperatures rise, a greater viscosity oil is frequently utilized.
It is critical to consult your vehicle’s owner’s handbook in order to determine the proper oil to use.
If you have your oil changed at a mechanic, find out what kind of oil they used.
3. Signs of Engine Wear
If you check your dipstick and it indicates that you have adequate oil and that the viscosity is correct, it might be an indication that your engine is beginning to wear. The oil must be able to freely flow through a lot of moving elements of an engine to function properly. At high mileage, the engine bearings, in particular, are prone to wear, which might result in a decrease in oil pressure, as previously stated. There are several elements that influence how long an engine will operate before displaying indications of wear and burning oil at a faster rate.
If you drive a car or truck that gets a lot of use, you should be proactive about keeping the engine in good condition. What to do – You should get your engine inspected by an engine professional to determine whether or not worn engine parts are to blame for the problem.
4. Oil Pump Failure
Checking your dipstick and seeing that you have adequate oil and that the viscosity is correct might be a warning that your engine is starting to wear down, according to the manufacturer. A motor contains several working elements, all of which require that oil flow freely through them. At high mileage, the engine bearings, in particular, are prone to wear, which can result in a decrease in oil pressure, which is undesirable. There are several elements that influence how long an engine will operate before displaying indications of wear and burning oil at a faster rate.
It is necessary to get your engine evaluated by an engine professional in order to determine whether worn engine parts are the source of the problem.
5. Clogged or Dirty Oil Filter
Oil filters aid in the removal of pollutants, dirt, and other debris from engine oil, which is beneficial. These particles can accumulate over time, and if an engine is not protected by a filter, they can cause significant damage. Filters can only contain a certain amount of material before they need to be replaced. If your filter is beginning to clog, less oil will be able to circulate around the engine, resulting in a reduction in engine pressure. To remedy the situation, consult with a professional and have the oil filter examined and replaced, if necessary.
What Is Normal Oil Pressure on a Semi-Truck?
This varies based on the sort of engine you have. The usual operating oil pressure for most semi-trucks is between 40 and 50 pounds per square inch (PSI) (pounds per square inch). It is important to remember that it takes around 20 minutes for an engine to achieve its maximum working temperature. It is also possible that your blood pressure will decrease if you spend a lot of time sitting still. Trucks are equipped with an oil pressure gauge, which displays the oil pressure in pounds per square inch (PSI), as well as a warning light in the event that the pressure becomes dangerously low.
One of the most important issues is the oil pressure.
Understanding Oil Viscosity
The term ‘viscosity’ is significant when talking about oil and how engines operate since it relates to how much oil is in the oil and how much pressure is in the oil in a semi-truck. The viscosity of a liquid refers to how ‘fluid’ it is and how it behaves to being compressed. It is a method of determining the amount of force required to oppose flow per unit area. In layman’s terms, and especially with regard to engine oil, the viscosity of the oil controls how readily the oil may flow around the engine and lubricate the engine.
It’s also vital to understand that engines can operate at temperatures ranging from 195 to 200 degrees Fahrenheit.
If you take a glance at the shelves of a car repair shop, you’ll find dozens of different oil kinds, each with a different viscosity rating, all of which are available for purchase.
It is critical that you choose which oil is the most appropriate for your car and that you only use the prescribed oil grade.

Oil Types, WeightsViscosity FAQ
Is it permissible to transfer motor oil weights, for example, from a 5W-20 to a 10W-30, without causing damage? It is dependent on the situation. A variety of recommended motor oil viscosity grades is provided by certain vehicle manufacturers, which are determined by the ambient temperature at which the vehicle is driven. Other manufacturers propose using only one viscosity grade of motor oil, while others recommend using two or three. Always adhere to the manufacturer’s recommendations, which can be found in your vehicle’s owner’s handbook, for the optimum engine performance.
- This is something Valvoline does not promote.
- A lighter grade than that required may result in increased mechanical wear and a shorter engine life than that advised.
- What does the ‘w’ in the designation of a motor oil grade mean?
- The first number in the oil classification refers to the viscosity of the oil in cold conditions.
- The flow characteristics of a 5W- motor oil are superior to those of a 15W- motor oil at lower temperatures, for example.
- If the value is more than one, then the oil is thicker at the chosen temperature.
- The use of thicker oil can be beneficial in some situations, such as when greater bearing clearances (the distance between a bearing and a spinning shaft) have accumulated over time.
Always follow the recommendations for motor oil viscosity in your vehicle’s owner’s handbook to get the maximum performance out of your vehicle.
The use of straight weight oil in a system that needs a multi-viscosity oil is not recommended under any circumstances.

What does the term ‘viscosity’ mean exactly? The viscosity of a liquid is a scientific term that describes how thick or thin a liquid has become. Due to the fact that water flows relatively quickly, it is considered to have a thin or low viscosity (see below). Honey has a higher viscosity than water, but it still has the ability to flow freely. Peanut butter has a viscosity that is extremely high. Try to remember the last time you tried to pour peanut butter from a jar onto a peanut butter and jelly sandwich.
I wish you the best of luck with it.
Viscosity and Your Car’s Engine
As oil circulates through your engine, it covers the moving elements of the engine, preventing them from grinding against one another and wearing down. Engine oil also serves to clean, cool, and protect the internal combustion engine. When evaluating engine oils for your vehicle, the viscosity rating of the oil is the most crucial factor to consider. Look in your owner’s handbook for the viscosity grade(s) recommended by the original equipment manufacturer (OEM), which may be found in the specifications section.
When looking for an oil, think of Goldilocks and her porridge: you want something that is neither too thin nor too thick, but something that is just perfect.
How to Read Viscosity Ratings
You’ll need to know the viscosity rating of the oil in order to choose which one is best for your car’s engine. It is possible to find the viscosity rating of the oil right on the bottle itself. Viscosity grades are assigned to all motor oils by the Society for Automotive Engineers, with the most common viscosity grade being 5W-30, according to the organization. Keep in mind that anything to the left of the dash represents the cold weather rating, since W is an abbreviation for ‘Winter,’ when looking at this series of numbers and characters.
The viscosity rating at engine operating temperature is shown by the number to the right of the dash.
The number indicates how thin the oil is; the lower the number, the thinner the oil.
The designation ‘5W’ indicates that the engine will continue to pump even at -35 degrees Celsius, which is the lowest temperature at which the oil has been tested.
Using motor oil that is too thin may result in engine durability difficulties, whilst using motor oil that is too thick may result in the engine operating at a lower efficiency.
Conventional or Synthetic?
Modern motor oil formulas are generally 80% base oil and 20% additives, with the remaining 20% being other ingredients. The base oil might be either conventional or synthetic, or it can be a combination of the two. Detergents, dispersants, antioxidants, friction modifiers, viscosity index improvers, inhibitors, anti-wear additives, and other additives are included in the list of available options.
Conventional base oil is derived solely from crude oil and includes a high concentration of contaminants. Additives aid in the improvement of the basic oil, hence ensuring proper engine protection.
In addition to chemically developed methods, synthetic base oil has undergone further refinement, resulting in molecules that are smaller, more consistent in shape and size, and with fewer contaminants than conventional oil. Aesthetic motor oils, on the other hand, have greater high and low temperature performance, and are typically prepared with higher performing additives to provide these benefits.

Motor Oil Viscosity Warning
It is possible to cause major difficulties by using the incorrect motor oil viscosity, including early wear, a check engine light, and even camshaft damage. Read this article to find out what viscosity of motor oil you should be using. Do you believe it will never happen to you? Take a look at this page to find out what produces the P0014 error code. P0014 cam phaser fault code is shown. This is only the first of a series of articles. If you would want to learn more about oil, please see the resources provided below.
- High-mileage oil and oil filters are available.
- What is the finest brand of cooking oil?
- When should you replace your oil?
- Oil pressure is used to run the timing belt and timing chain tensioners, as well as the variable valve timing devices, in today’s cars (VVT).
- Using the incorrect oil or the incorrect viscosity oil can have a negative impact on variable valve timing performance and cause cam timing to be off, and it can even cause the 3-lobed cam and high pressure fuel pump to fail.
This is a good example: just when you believe that you know more than the engineers, you learn that there was a method to their madness.
Oil viscosity and variable valve timing
The camshaft timing is altered by moving the cam in relation to the cam belt or timing chain, which is controlled by the variable valve timing. The rotation is carried out with the help of pulsed oil pressure. The PCM makes the assumption that you have used the right oil viscosity in order to command a cam timing modification and then examine the results. It is possible that switching to a higher or lower viscosity oil can affect the operation of the camshaft VVT solenoid or phaser, resulting in the computer not seeing the cam timing result that it expects.
Poor cam timing can cause a variety of performance difficulties, ranging from rough idle to lack of power, depending on the vehicle.
Various oils produce different outcomes, and these findings are not in accordance with what the PCM expects to find.
GDI engines and oil viscosity
The camshaft timing is altered by moving the cam in relation to the cam belt or timing chain, which is controlled by the variable valve timing system. Pulsed oil pressure is used to perform the rotation. The PCM makes the assumption that you have used the appropriate oil viscosity in order to command a cam timing modification and then examine the outcomes. By changing the viscosity of the oil, the performance of the camshaft VVT solenoid or phaser will be altered, and the computer will not see the cam timing results that it expects to see.
Poor cam timing can cause a variety of performance concerns, ranging from rough idle to lack of power, depending on the application.
Various oils have different results, and these results are not in accordance with what the PCM wants.
Causes & Symptoms of Low Engine Oil Pressure
The low-pressure engine oil lamp has shown on your dashboard, but what does it mean? And what should you do if anything like this happened to you while driving? Learn about the reasons of loss of oil pressure as well as how to carefully manage the situation if it occurs to you.
Symptoms of Low Engine Oil Pressure
It is possible that your sensor will trigger your oil warning light on the dashboard if the oil pressure falls below an acceptable level. If you see that it is illuminated, locate a safe location to pull over — ideally a parking lot, gas station, or service station — and check the amount of your engine oil.
Although it is still advisable to have the vehicle towed to a repair facility if the oil level is right, A defective oil pressure sensor might be to blame, or you could be dealing with a more serious problem altogether.
Diminishing Engine Performance
If you notice that your engine is suddenly losing power, stopping, or burning through your petrol tank at an alarming rate, you may be experiencing diminished engine performance. Even while this decline might be indicative of a variety of vehicle concerns, one of the most prevalent causes is low engine oil pressure. To begin, start simply by checking your oil level to see whether or not you require a simple oil and filter replacement.
Burning Oil Smell
A burning oil smell might indicate that your vehicle is leaking oil, and that this oil is coming into contact with a hot surface on a component in your vehicle. An unpleasant odor usually signals the presence of a leak, which might result in decreased oil pressure. If you notice the smell of burning oil while driving, stop at a gas station or parking lot where you may safely pull over to check your oil level before continuing.
When your engine’s oil level falls below a certain level, the lubrication that the engine’s components require to perform correctly is cut off. You may begin to hear clunking, banging, ticking, or grinding noises emanating from the engine of your car as a result of this. As a result, you’ll want to have your automobile serviced by a skilled mechanic as soon as possible.
It is engine oil that provides lubrication for the working elements of your engine. If your car’s engine does not have enough oil pressure, it will function with less lubrication and greater friction, resulting in increased heat production. Engine overheating can be a difficult problem to solve. Despite the fact that low engine oil pressure is not necessarily indicative of a problem, it might result in an overheated engine in some cases. Furthermore, an overheated engine causes wear and stress on the engine’s internal components.
What Makes Oil Pressure Drop?
The working elements of your engine are lubricated with engine oil. Your car’s engine will function with lower lubrication and higher friction, resulting in greater heat as a result of insufficient oil pressure. Overheating in an engine can be a difficult problem to deal with effectively. It is not usually the case that low engine oil pressure results in an overheated engine, but it is a possibility. In addition, an overheated engine causes wear and stress on the engine’s components and components.
Incorrect Oil Viscosity
When you use the improper oil viscosity, and especially a lower viscosity than what is advised in your car’s user handbook, the low oil pressure warning will illuminate. Lower viscosity oil can result in less resistance to flow, which can result in a decrease in oil pressure. Keep in mind, however, that a higher viscosity oil does not always imply greater safety. If it is greater than the manufacturer’s recommended value, it might cause flow resistance, which can result in poor engine lubrication and performance.
Bad Oil Pump
An oil pump malfunction can be caused by a variety of factors, including oil pollution, clogging of the oil pick-up tube, and incorrect installation. It is crucial to repair or replace the oil pump as soon as possible if it becomes faulty since the oil pump is responsible for transferring oil to the various components of your engine.
Examine whether the cause of your pump’s failure is just old age and wear, or whether it might be due to probable contamination, low oil levels, or inadequate maintenance. Contact your local Tires Plus store for assistance.
Dirty Oil Filter
The oil filter is in charge of capturing potentially damaging material and ensuring that it does not reach your engine. If it is not replaced on a regular basis, it might become too congested to perform its functions effectively. Oil filters are also included with pressure relief valves, which, if the filter element gets blocked, allow oil to bypass the filter element and flow freely again. Just before the oil filter becomes clogged to the point that oil can no longer travel through the filter media, the oil flow out of the filter will be decreased, which might result in a reduction in engine oil pressure.
Every oil change at Tires Plus includes the replacement of the oil filter.

Why Is My Low Oil Pressure Warning Light On
Oil is required for the survival of your engine. It will not be able to work properly without it, and it may cause significant or irreparable damage to the engine, not to mention harm to your pocketbook. When your vehicle’s low oil pressure warning light illuminates on the dashboard, it’s not anything you should be concerned about. However, if this occurs, you should quickly pull over and park. The low oil pressure light illuminates when there is insufficient oil pressure or when the oil level is too low in the vehicle.
When the engine is not properly lubricated, it might freeze up and cause irreversible damage to the engine.
This light on your dashboard, like the rest of your on-board diagnostic system, is a direct line of communication between your car’s computer and you, informing you of what is wrong with your vehicle.
The following are examples of common causes for the lighting of the low oil pressure light:
- No or insufficient oil — Maintaining your car is essential to keeping it on the road. It is recommended that you replace the oil in your car every 3-6 months or every 3,000–5,000 miles driven on the road. Thus, you can be assured that your engine will always have clean, fresh oil moving through it
- Worn-out crankshaft and camshaft bearings cause engine wear because oil travels throughout the engine and through the components they support. It is possible that the region has become wider as a result of worn components, resulting in excessive oil flow and reduced oil pressure. The oil pump is responsible for forcing oil through small spaces under bearings and passages. Because they regulate the rate of flow, they are the locations that cause pressure to build up in the system. In general, the higher the flow rate and pressure are, the quicker the engine is moving. Faulty It is possible that your engine has sufficient of oil in the pan and that everything is working well, but the problem is with the oil pressure gauge. Electrical faults and problems with the wiring might cause the gauge to malfunction and give a false reading, resulting in a fine. A technician will need to run a mechanical oil pressure test in order to identify whether or not there is a shortage of pressure in the engine oil. Air filter that has become clogged or dirty– Oil filters are critical in the maintenance of oil pressure. It is possible that the filter will get clogged, which will result in increased pressure and reduced flow. The presence of a pressure release valve on the oil filter prevents the pressure from rising to dangerous levels. A broken filter will be unable to perform its function, which will result in engine oil flowing more freely and pressure being reduced. Oil Viscosity– Thicker oil has a lower flow rate and a higher viscosity, which means it will not flow as rapidly as thinner oil. Depending on the time of year, this has an effect on the oil pressure. Oil with a high viscosity prevents oil pressure from building up quickly. Overheated of the engine– An overheating engine is not just a source of frustration for the driver. It is difficult on the engine because it causes the oil to thin, which prevents pressure from building up. It has a similar impact to using a lower viscosity oil than the vehicle’s specifications call for. In some cases, a malfunctioning oil pump might cause larger passages between the rotors, which results in a decrease in the rate of flow. While this is not typical, it can occur. Internal Components That Have Seen Better Days– Every component in the engine contributes to the combustion process. It is possible that oil will mistakenly enter the combustion chamber and burn, resulting in a decline in the engine’s oil level and pressure when these components fail. This is easily identified since it frequently emits a blue smoke that leaves via the exhaust pipe.
When the oil pressure is low, the oil pressure light flickers. It’s possible that when driving, you’ll notice that the low oil pressure warning light may flash on and off. This is due to the fact that the light will illuminate when the oil pressure falls below 5 – 10 PSI at idle, depending on the vehicle. If the pressure does not instantly diminish, you may also hear a banging sound. The reason for the light coming on or going off might also depend on whether or not your car is moving or at a standstill when it happens.
- When the vehicle is not moving, the engine should have a minimum of 5 PSI.
- If the light flickers while the car is moving, it is possible that the oil levels are too low.
- If the oil level was indeed low, the light should have turned off by now.
- This is an unpleasant circumstance since it has the potential to cause the engine oil to leak oil from the area where it was previously confined.
- By ensuring that your car receives normal maintenance, such as regularly scheduled oil changes, you can minimize the likelihood of your oil pressure light turning on in the first place.
- Ignoring low oil pressure in the engine might result in major difficulties within the block of the engine.
Don’t put off getting your engine inspected; else, you might end up with a blown engine. Contact a skilled specialist as soon as possible to assist you with keeping your engine operating smoothly.
What To Do If Your Engine Oil Pressure Warning Light Is On
Automobile Repair Library, Auto Parts, Accessories, Tools, Manuals and Books, Car BLOG, Links and Index are some of the resources available on this website. byLarry Carley (c)2019 AA1Car.com All rights reserved. Engine oil pressure warning lights may illuminate if your engine’s oil pressure has dropped below its usual operating level. Please come to a complete stop and turn off your engine immediately. If your engine’s oil pressure is low or non-existent, it can cause serious harm.
Symptoms of Low Oil Pressure
Warning for Low Oil Pressure a light that is on or flashing The readout on the oil pressure gauge is extremely low or zero. Noises from your engine such as ticking, rattling, or banging Engine power reduction or misfiring that occurs suddenly
Possible Causes of Low Oil Pressure Gauge Reading or Warning Light:
A low amount of oil (check the dipstick) a faulty oil pump Engine main and rod bearings that have worn out A serious engine oil leak has occurred (gaskets, seals, cam plugs or oil filter) The oil pressure transmitting unit is not working properly (oil pressure may be okay but the gauge is not reading correctly) Oil pressure gauge or warning light switch that is not working properly (oil pressure may be okay but the gauge or switch is defective)
Oil Pressure Warning Light Diagnosis
Check the dipstick to see if the oil is full or low, and then go from there. REMINDER: On some engines, there is an oil level sensor in the engine’s oil pan that, if the oil level is low, will activate the oil warning light, which will illuminate. If the oil level on the dipstick is low (the oil level is at or below the ADD line, or no oil can be seen on the dipstick), your engine may be leaking oil, burning oil, or a combination of the two problems. Check to check if the engine now has proper oil pressure after adding oil as needed and restarting the engine (normal gauge reading or oil pressure warning light off).
- If your engine’s oil level is low, top it off and check for leaks.
- There are several places where oil leaks can occur, including the valve cover, oil pan, and timing cover gaskets, overhead camshaft end seals or plugs, and the front and rear crankshaft oil seals, among others.
- Look for greasy spots, significant accumulations of grease, or oil leaking from the ceiling or onto the floor.
- The leaky gasket or seal in your engine should be changed if your engine is leaking oil due to a faulty gasket or seal in your engine.
- Even though the engine is in good condition on the outside, there are no evident leaks, and the oil level is low, your engine is most likely burning oil due to worn piston rings and cylinders as well as valve guides and valve guide seals.
- Oil consumption issues such as these can be extremely expensive to resolve since they may need the rebuilding or replacement of the engine.
- If the oil consumption is not excessive (for example, less than one quart of oil per 1000 miles), check your engine dipstick frequently and maintain adding oil as needed to avoid the oil level within the engine from becoming too low to prevent the engine from overheating.
- Carry some oil in the trunk of your vehicle and top it off as needed to keep the oil level in the engine above the ADD point on the dipstick.
The bad news is that your engine is nearing the end of its useful life and will most likely need to be refurbished or replaced in the near future. An increase in internal pump wear and leakage might result in a decrease in oil pressure.
Bad Oil Pump?
It is possible that the problem is caused by a damaged or malfunctioning oil pump that is unable to maintain proper oil pressure when the oil level is between ADD and FULL and the engine was generating noise while operating. The engine should not be started until the pump can be replaced. By adding a pressure gauge to the port where the oil pressure transmitting unit screws into the engine block, you can determine the oil pressure in the engine. As long as oil pressure is within specifications (10 psi for every 1000 rpm), the oil pump is in good working order, and the fault is most likely with an inoperative oil pressure sending unit.
This indicates that the oil level is between the ranges of ‘ADD’ and ‘FULL,’ and the engine continued to operate normally (with no noise) after the oil pressure warning light illuminated.
You should be able to start the engine and drive the car home or to a repair shop for repairs in most cases.
Low Oil Pressure Fixes
If the oil level in the engine is low, fill the engine with oil until the level on the dipstick reaches the FULL mark. It is important not to overfill the crankcase. Ensure that you use the type of oil viscosity specified in the owner’s manual for your vehicle. Alternatively, if the oil pressure gauge reading remains low or the oil pressure warning light remains illuminated, the sending unit for the oil pressure should be removed from the engine and a pressure gauge directly connected to the engine.
- It is not a bad oil pump, but rather a faulty oil pressure sending unit that is causing the problem if the pressure is normal (about 10 PSI for every 1000 RPMs of engine speed).
- Instead of using an old oil pressure sending unit, try replacing it with a new one if you don’t have a pressure gauge for testing oil pressure.
- However, if the warning light or low gauge reading continues to illuminate, the problem is most likely due to a faulty oil pump.
- The gears inside the pump and the pump housing and cover will wear over time, so low oil pressure on a high mileage engine (over 100,000 miles is not unusual) (over 100,000 miles is not unusual).
- This will also cause a loss of normal oil pressure.
- The pan must be removed to replace the pump.
- On other engines, the oil pump is located inside the timing cover on the front of the engine.
- Disassembly requires removing most of the components on the front of the engine to replace the pump.
This type of pump is much more difficult and time consuming to replace. If oil pressure is low because of worn engine bearings, the crankshaft bearings will have to be replaced. This usually requires overhauling or replacing the engine.

4 Common Causes of Low Oil Pressure Warnings in Your Vehicle
Despite the fact that all of your vehicle’s key fluids are crucial, just a handful demand as much specialized attention as your engine oil does. Engine oil may be thought of as the lifeblood of your vehicle; if something goes wrong with it, it can cause costly repairs as well as safety concerns with your vehicle’s engine. Modern automobiles, on the other hand, are frequently equipped with warning lights and sensors that can alert you to any problems with your oil. A lot of these alarms might be triggered as a result of low oil pressure, which is common.
We want to make you aware of the four most prevalent reasons of low oil pressure alerts, which are listed below.
First and foremost, you must ensure that the latest warning light on your car is not merely a false alarm before proceeding with the diagnostics process. Sensors in your Ford vehicle, like every other high-tech component of your vehicle, are susceptible to wear and tear. Sometimes, excessive wear on your vehicle’s sensors causes them to detect pressure levels erroneously, causing you to be alerted to problems that aren’t truly there. Especially if your car is an older model that you’ve had for a long period of time, this is likely to occur.
We can accurately diagnose any problem you may be experiencing at our dealership in a short period of time.
Oil Pump Malfunction
The oil pump in your automobile, as the name implies, is in charge of moving oil throughout the vehicle, ensuring that all vital parts are well lubricated. The oil pump provides pressure, which is then utilized to transport oil from the pan and guide it to the appropriate spots on the machine. If this pump fails, whether due to age, corrosion, or any other reason, air is allowed to flow into your oil, causing bubbles and, eventually, lowering your oil pressure. As a result, the warning systems in your vehicle may be activated.
Improper Grade Oil
Each vehicle, whether it’s a car, a truck, or an SUV, is distinctive. As a result, each vehicle has its own set of requirements, which is especially true in terms of its oil. When changing or topping off your oil, take additional precautions to ensure that you are using the oil blend and grade recommended by the manufacturer of your vehicle. This information may be obtained on the internet or in the owner’s handbook of your vehicle. Many different types of oils have different viscosities and intensities.
Because of this, the advanced warning systems in your Ford may be activated. If you’re not sure which oil is best for your vehicle, the knowledgeable mechanics at Gibbons Ford can assist you in selecting the appropriate oil for your vehicle.
Bad Oil Filter
Every oil change should be accompanied by the replacement of the oil filter as well. A well maintained oil filter is critical to the quality of your engine’s oil because it eliminates dust particles, metal fragments, and other debris that may otherwise cause harm to the internal mechanics of your vehicle. Over time, this filter can get clogged with the very material that it is designed to collect, allowing particles into your engine that should not have been there in the first place to enter by accident.
If you have any reason to believe that you may require oil-related maintenance, go no further than the knowledgeable staff at the Gibbons Fordservice facility.
We look forward to being of service to you!
