E85 Gasoline?

E85 (or flex fuel) is a term that refers to high-level ethanol-gasoline blends containing 51% to 83% ethanol, depending on geography and season (see Fuel Properties and E85 Flex Fuel Specification).


  • E85 gas (also known as flex fuel) is a high-level combination of ethanol and gasoline that consists of 51 percent to 83 percent ethanol blended with gasoline. The percentage of ethanol depends on the geographical location and time of the year. Producers add more ethanol in the summer as opposed to the winter. E85 ( Flex Fuel )

Is E85 gasoline the same as regular?

Fuel sold as E100 is always 100 percent ethanol, while fuel sold as E85 always contains 85 percent ethanol. When fueling their flex-fuel vehicles with E85 instead of regular gasoline, drivers won’t notice many differences other than a decrease in miles per gallon.

Can I use regular gas in E85?

Can regular gas be used in a flex-fuel vehice? Yes, standard gasoline can be used in flex-fuel vehicles. The engine inside FFVs is designed to run on gasoline as well as other fuels. This generally means gas blended with ethanol and methanol.

Is E85 gas the same as 87?

E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.

Is it bad to switch between E85 and gasoline?

Yes, you can mix them. It doesn’t matter. If you have a flex-fuel vehicle you can use any mix of gasoline and alcohol up to 85%. Chances are you don’t need to use the 93 octane fuel.

Can E85 damage my car?

Ethanol has a corrosive action on fuel-system components, magnesium, aluminium and rubber. Running E85 on older model engines without tuning and replacing some components will ruin the engine in short time. Replacing fuel hoses, fuel pumps, gaskets, seals, fuel filters, fuel injectors, throttle bodies, etc.

What is the difference between flex fuel and E85?

E85 or Ethanol Flex Fuel is a renewable energy made by fermenting and distilling corn. E-85 contains mix of 51% – 83% ethanol with unleaded gasoline. Flex Fuel should only be used in Flex Fuel ready vehicles.

What gasoline is ethanol free?

According to Dan McTeague, a noted petroleum analyst, Shell and Esso 91 are both ethanol free. All other grades from the companies have some ethanol content, but the mid-grade blend is pure gas, which means it not only corrodes less than ethanol blends, but is less likely to deteriorate when stored.

Does 93 octane have ethanol?

All gasoline brands have both pure and ethanol-containing gasoline under the same brand names. For example, Shell V-Power ranges from 91 to 93 octane both with and without added ethanol. It just varies from station to station, and it’s up to the station owner whether or not to sell pure gas.

Can I put 87 in an E85 car?

You may use non-ethanol gas (87 octane regular fuel) in your E85 vehicle. You will experience better gas mileage than using E85 in your E85 vehicle. You may not use E85 in a non-flex fuel (E85) engine. Your engine will run horribly and you may damage seals in the fuel system.

Can I mix E85 with 87?

Yes, you can. Provided your engine is designed to run on E85, you can feed it any ratio of E85/gasoline. You should not attempt this in an engine not designed to run on E85.

What is E85 gasoline used for?

E85 (or flex fuel) is a term that refers to high-level ethanol-gasoline blends containing 51% to 83% ethanol, depending on geography and season (see Fuel Properties and E85 Flex Fuel Specification). It can be used in flexible fuel vehicles (FFVs), which are available from domestic and foreign automakers.

How do I convert from E85 to gas?

When converting to E85, the general rule of thumb is to increase the overall capacity of your current fuel supply by 33 percent. For an EFI system, this typically involves 33 percent larger fuel injectors and a 33 percent larger fuel pump.

Does E85 make more power?

E85 fuel can give you a significant boost in power and torque without breaking the bank for racing fuels. It has a base octane rating of 105 and has the bonus of added cooling properties that add even more knock resistance than racing fuels with the same rating.

What Is E85 Gas? Everything You Need to Know

E85 gas (also known as flex fuel) is a high-level mix of ethanol and gasoline that contains 51 percent to 83 percent ethanol combined with gasoline. It is used in automobiles and other transportation vehicles. The amount of ethanol in a product varies depending on the geographical region and time of year it is produced. In the summer, as compared to the winter, producers increase the amount of ethanol they use.

E85 (Flex Fuel)

E85 is the most widely used type of flex fuel currently available on the market. The fact that ethanol is derived from maize means that E85 gas is commonly available in the Midwest area of the United States of America. Other regions, particularly New England and the Pacific Northwest, have a lower availability of this product. It is estimated that there are 3300 E85 gas stations available to the general public in 42 states, according to the United States Department of Energy. Alternative crops are frequently used by ethanol producers outside of the United States.

According to research conducted by the United States Energy Information Administration, pure ethanol has a lower heating value than gasoline, which makes it more difficult to start a car’s engine in colder weather conditions.

  • Gasoline blended with ethanol can be used in any vehicle that has been recognized by the manufacturer as a flex-fuel vehicle.
  • Consumers may use the Department of Energy’s vehicle cost calculator to figure out how much money they can save on fuel expenditures and greenhouse gas emissions by switching to a flex-fuel car.
  • Flex-fuel cars in Brazil operate on E100, as opposed to E85, which is available for purchase in the majority of other regions of the world.
  • It is simpler for a vehicle to achieve optimal performance and fuel economy when a guaranteed proportion of ethanol is used in the fuel.
  • The motor racing industry has long chosen ethanol- or methanol-based fuels since these fuels tend to provide higher thermal efficiency and enhanced torque to high-performance vehicles than other fuels.
  • By offering subsidies to maize growers in the Midwest, the government in the United States has attempted to stimulate the manufacture and sale of E85 gasoline.
  • Because of this new infrastructure, E15 and E85 will become more widely available across the country.
  • When compared to gasoline, ethanol produces less energy per gallon, which means that the higher the amount of ethanol in a fuel, the greater the influence on fuel efficiency and the reverse.
  • E85 gasoline is less expensive at the pump than ordinary gasoline; but, because of the reduction in miles per gallon, it is more expensive when driving.

While flex-fuel cars achieve lesser miles per gallon when using E85 instead of conventional gasoline, they often produce higher torque and horsepower. There are advantages and disadvantages to utilizing E85, just as there are with any consumer product. The advantages are as follows:

  • Less reliance on imported oil
  • Less air pollutants emitted into the atmosphere
  • Greater resistance to engine knocking
  • And lower operating costs.

The following are some disadvantages to bear in mind:

  • Use is restricted to flex-fuel cars only
  • The use of less energy per gallon translates into fewer miles per gallon. Some locations do not have easy access to this product


Ethanol is a type of alcohol fuel that may be produced from a variety of plant materials, including maize, sugar cane, and several grass species. It is a renewable resource that is generated in the United States rather than imported from other countries. According to the United States Department of Energy, the usage of ethanol can lead to a reduction in reliance on oil as well as a reduction in greenhouse gas emissions into the environment. E10 and E15 are two alternative mixtures of ethanol and gasoline that are available in addition to E85.

  1. Regular gasoline marketed in the United States often includes up to ten percent ethanol by volume.
  2. It is common for drivers to notice a loss in miles per gallon when they switch to E10 or E15 instead of regular gasoline.
  3. A ten-percent mix is not considered to be flex fuel.
  4. Flex fuels are used in hybrid vehicles.
  5. They can operate on a variety of fuels, ranging from pure gasoline to mixes including up to 85 percent ethanol.

Fuel Economy

Society of Automotive Engineers and other proponents of ethanol-based fuel argue that if automotive manufacturers would recognize and take advantage of the superior characteristics of ethanol-based fuel, they could create an ethanol engine that was just as efficient or even more so than a gasoline-powered engine. Several of these proponents claim that an ethanol engine that can provide up to 22 percent more mileage per gallon than a gasoline engine is now available. They argue that it is incorrect to build an ethanol engine on the same principles as a gas engine when ethanol is more similar to diesel fuel.

  • Opponents reject that claim by pointing out that the heating value does not play a role in determining total energy efficiency.
  • E85 also has a greater octane percentage than regular gasoline, which can result in increased engine power.
  • E85 and other flex fuels will be around for a long time, thanks to increased public acceptance and government subsidies.

E85 – Wikipedia

Logo used in the United States to represent E85 gasoline. In most cases, the acronym E85 refers to an ethanol fuel mix consisting of 85 percent ethanol fuel and 15 percent gasoline or other hydrocarbon fuel by volume. Depending on the specific ratio of gasoline ethanol to hydrocarbon in the United States, ASTM 5798, which specifies the permitted ethanol concentration in E85 as ranging from 51 percent to 83 percent, may be used. In part, this is due to the lower heating value of fresh ethanol, which makes it difficult to crank engines in cold areas without pre-heating the air intake, cranking at a higher rate, or mixing different percentages of gasoline depending on the temperature.

  • Due to the fact that ethanol fuel is readily available at the pump in Brazil, flexible-fuel vehicles (FFV) such as trucks, tractors, motorcycles, and mopeds may operate on E100.
  • As a result of the assured ethanol percentage, there is no longer any need for a vehicle system to compute the appropriate engine tune in order to maximize performance and fuel efficiency.
  • Because of its inherent combustion characteristics, such as high thermal efficiency, increased torque, and in some advanced engines, better specific fuel consumption, alcohol (ethanol and methanol) has been used in motor racing since the invention of the automobile.
  • In the United Regions, government subsidies for ethanol in general and E85 in particular have aided in the development of a developing infrastructure for the retail sale of E85, particularly in corn-producing states in the Midwestern United States

Fuel economy

Fuel blends based on ethanol, according to E85 proponents and the Society of Automotive Engineers, are currently failing to match the fuel consumption of gasoline because automobile manufacturers do not take use of the qualities that are superior than gasoline in ethanol-based fuel mixes. Several ethanol engines, according to the researchers, have already achieved 22 percent more mileage per gallon than equivalent gasoline engines. Ethanol proponents also argue that basing ethanol engine design on gasoline engine design is a mistake, and that ethanol engines should instead be based on diesel engine design specifications, rather than gasoline engine design.

The composition of the ethanol-gasoline blend, the gearbox, and the quality of the engine’s tune all influence the mileage (primarilyfuel-air mixture, spark timing and compression ratio).

In the United States, legislation has been established to subsidize the cost of ethanol in order to compensate for the difference in fuel consumption in cars that are not optimized for ethanol.

Energy value

E85 skeptics, on the other hand, argue that the benefits of E85 are outweighed by the fact that E85 has a 33 percent lower heating value than gasoline, despite the fact that gasoline has a greater heating value. However, comparing energy reported as a heat value does not accurately reflect the overall amount of work done by an Otto Cycle. Considering only heat in the combustion equation does not yield an accurate determination of efficiency or work according to the laws of thermodynamics since certain latent and specific heat values, as well as combustion pressure, are not taken into consideration.

Octane rating

Engines obtain larger power advantages when more work is put into optimizing them to take advantage of E85’s higher “octane” and higher “fuel efficiency.” One automobile that has greater power while running on ethanol is the Koenigsegg CCXR, which is the sixth most powerful production car when running on ethanol and has 20 percent more horsepower when running on E85 than when running on gasoline.

  • According to the manufacturer, this is owing to the cooling qualities of ethanol in the air conditioning.
  • Due to this, it may be utilized in engines with greater compression ratios, which have the tendency to create more power per unit of displacement than their gasoline equivalents.
  • Despite the fact that certain cars were not designed to run on E85, some may be adapted to do so.
  • This, together with its high stability level resulting from its high octane rating, has led to its employment as a “power adder” in turbocharged performance cars with increased horsepower.
  • Power increases of up to 40% are possible in situations where the engine was previously knock restricted by gasoline.
  • This is due to the low price (less than $2.00/gal in some areas) and wide availability in some areas.


There are four basic categories of contaminants that scientists are interested in studying. Hydrocarbons (HC), nitrogen oxides (NO x), carbon monoxide (CO), and carbon dioxide (CO2) are among the pollutants released (CO 2). Because E85 contains a significant amount of ethanol, the exhaust emissions are significantly different from those produced by ordinary gasoline. Multiple studies have been conducted to compare and contrast the various emissions and the impacts that these emissions have on the ecosystem, but the results have come up with no definitive answers.

  1. The brand and type of the vehicle, the method by which the ethanol was created, and the overall fuel economy of the vehicle all play a significant part in determining the ultimate conclusion of any research study.
  2. On average, all emissions that are federally monitored showed a decrease or showed no statistically significant difference between E85 and gasoline, according to this collated collection of statistics.
  3. However, as compared to regular gasoline or lower-volume ethanol blends, E85 has the potential to cut emissions of some pollutants even more.
  4. Using E85 also helps to reduce carbon monoxide emissions while also reducing emissions of a variety of dangerous toxics, including benzene, which is a recognized human carcinogen, by a substantial amount.

However, when used in specific engine operating circumstances, E85 may cause an increase in acetaldehyde emissions. The Environmental Protection Agency is doing more research to improve our understanding of the emissions consequences of E85.


According to a study conducted by Purdue University, the economic value of using E85 is heavily reliant on the price of crude oil.

Food vs. fuel

E85 detractors argue that the manufacturing of ethanol from corn (maize) drives up world food costs, making corn costly or even inaccessible to many people throughout the world. Proponents of E85 argue that more than 93% of all maize cultivated in the United States is never given directly to humans, but is instead utilized as animal feed. Sweet corn, for example, is not easily digested by humans, but maize used to generate ethanol includes a large quantity of starch and is. American farmers produce more corn than the country’s consumers consume, resulting in a yearly surplus of maize in the United States.

Some detractors of ethanol argue that the use of petroleum and natural gas in the production and refining of ethanol will not result in significant reductions in carbon emissions.

The production of ethanol from waste materials or quickly growing non-food crops such as switchgrass, according to some, is far more beneficial but not yet economically feasible on a wide scale.

Availability and price

E85 detractors argue that the manufacturing of ethanol from corn (maize) drives up world food prices, making corn costly or even inaccessible to many people in developing countries. E85 proponents address this argument by pointing out that more than 93 percent of all maize cultivated in the United States is never given directly to humans, but is instead utilized as livestock feed. Sweet corn, for example, is not easily digested by humans, but maize used to generate ethanol includes a large quantity of starch.

Those in favor of E85 argue that corn prices have increased as a result of market manipulation and because American corn companies are selling more and more US-grown corn to countries such as Mexico and China, increasing competition among corn buyers and, as a result of this, driving up the price of grain.

As an answer, proponents of E85 refer to ethanol producers who don’t do so, but instead utilize E85 or biodiesel fuel to transport E85 and biomass as a heat source for the distillation of ethanol, rather than petro-products such as natural gas to do so.

Many others believe that the world can easily replace all of its petroleum consumption by simply producing ethanol from the many crops that produce more ethanol per acre than corn yields, using existing technology rather than future technology, and that certain elements in the cellulosic ethanol field are more concerned with patent rights than they are with producing the greatest amount of ethanol at the lowest possible price level.

US price regulation

The Volumetric Ethanol Excise Tax Credit (VEETC) was established by the American Jobs Creation Act of 2004 to support the expenses of ethanol production. The VEETC’s 51-cent tax credit was decreased to 45 cents as part of the 2008 Farm Bill. There have also been other steps taken by Congress to jump-start ethanol production, such as the 2004 VEETC law, which established the Small Ethanol Producer Tax Credit, which provides tax credits to small ethanol manufacturers. Recent legislation such as the Tax Relief Act of 2010, the Unemployment Insurance Reauthorization Act of 2009, and the Job Creation Act of 2010 extended the tax breaks provided by the VEETC from the end of 2010 to the end of 2012.

As recently as 2011, E85 was at least 20 percent less costly than gasoline in most places.

According to the Australian Automobile Association (AAA), where Holden has sold over 70,000 FFVs since 2010, the variation in combined consumption between identical V8 models in a family sedan is between 10% and 20%.

The same fleet of Ford Tauruses, however, averaged just approximately 6 percent fewer miles per gallon in ethanol-based vehicles when compared to standard gas-powered Tauruses in another test.

Should You Use E85 Fuel In Your Vehicle?

Are you thinking about making the move to E85 flex fuel to save money? If this is the case, you may be asking whether flex fuel is the best option for your vehicle. We’ll assist you in determining whether or not you should switch to E85 flex fuel. We’ve compiled a list of questions that you’ll need to respond to. It is totally worth it to make the move to flex fuel if you can answer “yes” to any of these questions with confidence. Please keep in mind that some vehicles are already compatible with E85.

Don’t be concerned if your vehicle falls into the latter group.

All that is required is the installation of aneFlexFuel E85 capability kit.

Do You Want To Increase Your Engine’s Power Output?

E85 is a high-octane gasoline. It has an octane rating of 100+, which means it is extremely powerful. In fact, E85 has the highest octane rating of any gasoline on the market. It makes it possible for the engine to function more efficiently, to advance the spark, and to resist knocking. This increases the amount of power that can be extracted from an engine. One of oureFlexPlusoreFlexProE85 capability kits will provide the opportunity to either choose an existing high-performance tune for your engine or design a custom one from scratch.

This can result in an increase in horsepower of anywhere from 3 to 20%. According to your engine and how it has been adjusted, the exact quantity varies.

Do You Want To Save Money On Fuel?

E85 is typically significantly less expensive than gasoline. It is often 25 percent to 35 percent less expensive than other high-octane fuels, depending on the region. You’ll save a lot of money on gas this way. The use of E85 can reduce your vehicle’s MPG by up to 25%, however many vehicles only lose 15 percent to 20% of their fuel efficiency in this situation. Even if your vehicle’s mileage drops by 25 percent, you will still save money over the long run. For example, you may burn a 60/40 blend of E85 and gasoline with minimal or no reduction in fuel economy while using any of our capability packages.

In this post, you may learn more about how E85 impacts mileage and how you can save money by using it instead of regular gasoline.

Do You Want Your Engine To Last A Long Time?

E85 burns far more cleanly than gasoline. It also burns at a lower temperature. As a consequence, E85 helps to avoid carbon buildup, which is the most common cause of ring and valve wear in automobiles. The ethanol in E85 performs an excellent job of cleaning away the deposits that accumulate:

  • In the combustion chamber, in the fuel injectors, on the valve stems, and so on.

To the point that many folks would run one or two tanks of E85 through their engine to clear it out. The longer your engine is kept clean, the longer it will last.

Do You Want To Reduce Your Carbon Footprint?

Ethanol is a renewable resource that can be recycled. It’s also made right here in the United States of America. When compared to pure fossil fuel, it is far better for the environment. E85 as a major fuel source can lower your vehicle’s carbon footprint by up to 50%, depending on your driving habits. As a result, when it comes to environmentally friendly transportation, E85 is the second best option behind electric vehicles.

Do You Want To Support American Farmers?

Renewable resources such as ethanol exist. Also made in the United States of America. It is far better for the environment than using only fossil fuels in their pure form. E85 as a major fuel source can lower your vehicle’s carbon footprint by up to 50%, depending on how you use it. As far as environmentally friendly alternatives go, E85 is the next best thing to electric automobiles.

Switching To Flex Fuel Is Easier Than Ever

You are not required to give up your vehicle in order to switch to flex fuel. In the event that you like your car, you can keep it and upgrade to an eFlexFuel E85 capable kit. It is a kit that allows you to make your vehicle compatible with E85 fuel without having to replace any of the components in your vehicle.

4 Valuable Benefits of E85 Fuel

10th of October, 2019 When you’re filling up your car with gas, how often do you think about the word “renewable”? A renewable fuel generated from sugarcane or maize, ethanol is one of the many options for alternative transportation fuels. Specific to E85 is a gasoline mix that can be beneficial to both you and the environment in which you live. Continue reading to learn about four important advantages of using E85 gasoline. E85 Fuel – What It Is and How It Works E85, often known as “flex fuel,” is a gasoline-ethanol combination that can include up to 85 percent ethanol depending on the time of year.

  1. The proportion of ethanol in E85 can range from 51 percent to 85 percent depending on the brand.
  2. The proportion of ethanol in E85 fuel is affected by the outside temperature, just as there are varying mixes of fuel depending on the season.
  3. It is important to note that not all vehicles are compatible with E85, so double-check your vehicle before filling up.
  4. In part because of the modest amount of energy that E85 generates within an engine, flex fuel has the potential to result in lower emissions of some pollutants.
  5. More Horsepower is always better.
  6. Because of its capacity to withstand compression and explosion, it would improve the rate at which an engine would operate.
  7. Gallon of gas is less expensive.
  8. If you compare the average cost of premium gasoline, flex fuel is significantly less expensive to fill up on.
  9. Job Creation in Rural Areas If you reside in a rural town, you should be aware that alternative fuels such as E85 are also providing employment and strengthening the local economy.
  10. Is E85 a good fit for your fuelling needs?

If this is the case, contact Home Service Oil. We take great pride in delivering gasoline to your farm or business property as promptly and effectively as possible whenever you require it. In order to learn more or to request our services, please call us at 1-800-467-5044 now.

Can you use regular gas in a flex-fuel vehice? Regular Gas and FFVs

Flex-fuel vehicles, often known as FFVs, are cars that have been specially designed to run on ethanol and methanol-based fuels. What happens, though, if you fill the tank with ordinary gasoline? Is it possible to use conventional gas in a flex-fuel vehicle? View our selection of previously owned Flex-Fuel vehicles. Standard gasoline may be utilized in flex-fuel cars, which is correct. Of addition to running on gasoline, the engine in FFVs is intended to run on a variety of different fuels. This often refers to gas that has been combined with ethanol and methanol.

What fuels should not be used in an FFV?

It is not recommended to use diesel or ordinary leaded gasoline in an FFV. Although leaded gasoline is quite rare these days, if you do manage to stumble across some, make sure to keep it out of your FFV’s fuel tank. In most cases, the flex-fuel label indicates that you may use either E85 gasoline or conventional unleaded gasoline in your car.

Does using regular gas in a flex fuel vehicle harm the engine?

No. A car that has not been intended to run on E85 is potentially hazardous to its performance. Have you ever wondered why there is so much oil in the Middle East?

What does the number in flex-fuels mean?

The number after the E on a gasoline label such as “E85” refers to the amount of ethanol that has been blended in. ethanol-based fuels such as E85 are made of 85 percent ethanol.

How does ethanol affect fuel economy?

When it comes to most FFVs, the higher the percentage of ethanol in the gasoline, the greater the reduction in fuel efficiency. The reason for this is because ethanol burns at a higher rate than conventional gasoline.

Is ethanol better for the planet?

Most FFVs see a decrease in fuel efficiency as a function of the amount of ethanol present in the fuel. The reason for this is because ethanol burns at a higher rate than gasoline.

E85 Gas and Flex Fuel FAQ

E85 Gas (also known as flex fuel) is a blend of gasoline and ethanol that is meant to be used in Flex Fuel Automobiles. It is a renewable energy source that is produced by the fermentation and distillation of corn. E-85 is a blend of ethanol and unleaded gasoline that ranges from 51 percent to 83 percent by volume. E85 gas should only be used in cars that are compatible with Flex Fuel.

What is Flex Fuel?

E85, sometimes known as ethanol, is a type of fuel that contains ethanol. Fermenting and distilling maize results in the production of Flex Fuel, which is a sustainable energy source. E-85 is a blend of ethanol and unleaded gasoline that ranges from 51 percent to 83 percent by volume. Flex Fuel should only be utilized in cars that are capable of running on it.

E85 Gas vs Flex Fuel

Flex Fuel and E85 gas are both the same thing; we only refer to them by two different names to distinguish them.

E85 vs 87 Unleaded Gasoline

While Flex Fuel and E85 gas are both the same thing, they are referred to differently in our language.

Is there E85 near me?

If you live in California, the answer is a resounding YES! If you are looking for an E85 gas station near you, check out the Pearson fuels Flex fuel station map on our website.

Is there an E85 Gas App?


Pearson Fuels has an E85 gas app that can assist you in finding E85 gas stations near you. You can download the Pearson Fuels station locator app by clicking here.

Can I put flex fuel in my car?

Check the gasoline door for a yellow gas cap or fuel filler ring, and look for a yellow gas cap or fuel filler ring. The presence of “Flex-Fuel,” “E-85,” or “FFV” emblems on the exterior of your car shows that your vehicle is capable of running on E85. However, if such signs aren’t installed on your vehicle, consult your owner’s handbook, which should say “Gasoline/Ethanol” if your vehicle is compatible with either fuel.

What are advantages of using E85?

  • You’ll save money at the pump
  • You’ll help the American economy
  • You’ll reduce CO2 emissions.

What do I do if I accidentally use E85 in conventional car or diesel?

Save money at the pump:; Support the American economy:; Reduces CO2 emissions:; Save money on groceries:;

Can I convert to Flex Fuel Car?

The use of aftermarket conversion kits is not recommended since the fuel systems of conventional automobiles are not capable of delivering E85 fuel efficiently. Even if these modifications make it possible for a traditional engine to operate on E85, the cars’ long-term performance may be compromised due to the incompatibility of the materials used in the fuel system.

What is a Flex Fuel Vehicle?

Flex Fuel vehicles (FFV) are cars that can operate on gasoline or gasoline-ethanol mixtures up to 85 percent ethanol (E85) and still be roadworthy.

What is E85 Gas?

Christian Lantry captured this image for Cars.com. Brian Normile contributed to this article. 9th of May, 2020 When it comes to gasoline, it’s called E85 since it’s theoretically comprised of up to 85 percent ethanol. However, it includes between 51 percent and 83 percent ethanol, depending on the season, according to federal regulations set by the Environmental Protection Agency (EPA). Ethanol is a kind of alcohol that is generally produced from maize in the United States, which is why gas stations that sell E85 gasoline are most prevalent in the Midwest.

The price of E85 is typically lower than the price of regular gasoline — approximately 9 percent lower as of this writing — but it is also less energy-dense than regular gasoline, which can lead to a reduction in miles per gallon of 15 percent to 27 percent.

Regular gasoline, sometimes known as E15, is now permitted to include up to 15 percent ethanol.

Car and truck owners who want to improve their vehicle’s performance on a drag strip, for example, may choose to alter their vehicle’s engine and engine software to accept the higher ethanol concentration of E85 gasoline.

What Is Flex Fuel?

For those who are interested in an automobile context approximately 2020, the quick answer is that it is a technology that permits an engine to burn any combination of alcohol and gasoline ranging from 15 to 85 percent anhydrous ethanol by volume. It is necessary to have equipment such as fuel-system piping that is resistant to the more corrosive alcohol, as well as an onboard sensor suite that can calculate the precise mixture % in real time and alter the engine ignition system as needed (so the driver need not manually re-jet the carbs as on a Model T).

The precise composition of the combination might vary within that range based on the season and geographic area.

How Does Flex Fuel Work?

With a few notable exceptions, a flex fuel vehicle operating on E85 will perform nearly identically to a conventional vehicle running on pure gasoline. In most cases, the pump octane number of E85 is 110, as opposed to the 84 to 93 of gasoline. This indicates that it can sustain greater compression before auto-igniting, or “knocking,” as contrast to gasoline. In other words, it is feasible to run a little more spark advance and so get a little more power out of an engine operating on E85 than the same engine can generate when running on ordinary or premium unleaded petrol.

In comparison to today’s pump gasoline, which contains 10 percent ethanol on average since 2010, fuel economy normally decreases by 15 to 27 percent.

Is Flex Fuel Good for the Environment?

Certain entrenched interests would have us assume that there is a lot more to it than there actually is. Today, corn is used to produce the great majority of the ethanol that we use to combine with gasoline. Producing corn, without a doubt, absorbs CO2, but because most of the American farmland used to produce corn, or another food or feed crop, prior to subsidies and other incentives redirecting that corn to fuel production, the global CO2 uptake did not increase when that corn was redirected to make alcohol.

Only then can the CO2 absorbed during the production of the fuel be considered to be truly offset by the CO2 emitted after its burning in a vehicle.

Furthermore, because the starches in maize must be broken down in order to generate sugars that can be distilled into alcohol, the process of turning grain to ethanol is energy-intensive.

In order to compensate for this, it takes around 30% more energy to manufacture ethanol from corn than it does to produce ethanol from sugar cane, thus weakening the argument for maize ethanol as a fuel in the global marketplace.

Does Flex Fuel Save Money?

Adding flex-fuel capacity to a new vehicle is inexpensive, and the expense is seldom passed on to the consumer because flex-fuel capability has long been associated with improved Corporate Average Fuel Economy (CAFE). As a result, the calculation is largely concerned with whether or not your local fuel cost relative to gasoline is decreased sufficiently to compensate for the predicted 15 to 27 percent drop in fuel economy that may be expected with E85 use. At the time of this writing, the Environmental Protection Agency estimates a national average cost of $2.28 per gallon for E85 and a national average cost of $2.25 per gallon for standard unleaded fuel.

There are a few caveats: It is possible that drivers in the Midwest may find E85 priced at a low enough level to allow driving on E85 a financially viable option; but, if your location and season place you in the 51 percent blend, the range reduction will be far less, and your results may vary greatly.

At the time, E85 was retailing for 80 cents per gallon cheaper than gasoline in Michigan, so I was able to save even more money.

What Vehicles Run on Flex Fuel?

Adding flex-fuel capacity to a new vehicle is inexpensive, and the expense is rarely passed on to the consumer because flex-fuel capability has long been associated with increased Corporate Average Fuel Economy (CAFE). Consequently, the calculation is centered on whether or not your local fuel cost relative to gasoline is decreased enough to offset the estimated 15 to 27 percent drop in fuel economy that may be predicted with E85. E85 costs $2.28 per gallon on average in the United States, according to the Environmental Protection Agency, whereas conventional unleaded petrol costs $2.25 per gallon on average.

The following are some cautions to bear in mind: It is possible that drivers in the Midwest may find E85 priced at a low enough level to allow driving on E85 a financially viable option; but, if your location and season place you in the 51 percent blend, the range reduction will be far smaller, and your results may differ significantly.

A month ago in 2014, I drove an E85 GMC Sierra Denalion and saved 2 cents per mile vehicle fuel expenditures. At the time, E85 was retailing for 80 cents per gallon cheaper than gasoline in Michigan, thus I was able to save money on petrol.

How Can I Tell if My Vehicle Is Flex-Fuel Compatible?

For a brief period of time, select General Motors and Ford cars were equipped with badging that said “Flex Fuel E85 Ethanol” or had a road/leaf symbol. However, the most reliable method is to open the fuel door and examine the decals as well as the color of the gas cap or capless filler neck. If they are yellow, the car is capable of running on flex-fuel. If not, please keep it at E10 or less.

Where Can I Buy Flex Fuel?

According to the Department of Energy, there are 3,300 E85 gasoline stations in 42 states now dispensing the fuel, with the greatest number concentrated in the Midwest. (According to some reports, the total number of stations might be as high as 4,800.) With 451 stations, Minnesota is the most populous state, followed by Illinois (298), with Michigan, Indiana, and Iowa each having somewhat more over 200. Alaska, Hawaii, Maine, New Hampshire, and Rhode Island are the only states that do not have public E85 stations.

The Department of Energy provides a zip-code station locatorhere.

Where Does Flex Fuel Come From?

It is a homegrown energy source, and as a result, it contributes to our nation’s reduced dependency on imported oil. The United States is the world’s largest producer of ethanol, creating over 16 billion gallons per year, with corn accounting for 98 percent of total production. The United States and Brazil produce 85 percent of the world’s ethanol (the majority of Brazil’s ethanol is derived from sugar cane), respectively. Six states in the Midwest account for 72 percent of overall production: Iowa, Nebraska, Illinois, Minnesota, Indiana, and South Dakota; the other states are Nebraska, Illinois, and Minnesota (listed in descending order of production).

Can I Still Buy Pure Gasoline?

It’s becoming increasingly difficult to locate, but station location maps are available for individuals who wish to operate their historic automobiles, boats, aircraft, or lawn mowers without the use of alcohol. At the time of this writing, their total number of pure-gas stations in the United States and Canada stands at 15,201.

What Does the Future Hold for Flex Fuel?

A political football has been used to divide the country over the use of ethanol as a fuel for years, putting corn-producing states in America’s Midwest against the rest of the country in a fierce war over fuels laws (the Iowa caucus going first in presidential campaigns makes it political suicide to be against ethanol). In response to the trend away from E85 compatibility in the new-vehicle market, the Renewable Fuels Association has turned its attention to boosting the “normal gas” blend from 10 to 15 percent.

All General Motors vehicles have been E15 compatible for nine years, and Ford vehicles have been E15 compatible for eight years, however Mercedes-Benz, Mazda, Mitsubishi, and Volvo still do not include E15 as an authorized fuel in their owner’s manuals.

As a result, for the foreseeable future, E15 will need to be labeled and marketed in conjunction with E10 gasoline.

Check the stickers attached to your vehicle’s fuel filler to see if it is rated to run on E15 and be prepared for the potential of significantly lower fuel efficiency and range when compared to when using E10 (or increasingly rare pure gasoline).

And don’t hold your breath for significant improvements in performance.

E85 vs. Gasoline Comparison Test

Concerns have recently been raised concerning the efficiency with which ethanol is produced. Some detractors have even claimed that ethanol is a “negative energy source,” meaning that it requires more energy to create than it produces when used as a fuel. It has come to light that there are more questions regarding the genuine environmental advantages of ethanol and E85. Furthermore, some opponents have expressed concern about the likelihood of food shortages when farmers shift from planting maize for food production to growing it for ethanol generation.

  1. However, our exam was not created to provide answers to those kind of questions.
  2. There will undoubtedly be individuals who choose to pay the higher price to run on E85 in order to promote the United States’ energy independence, which is a wonderful deed.
  3. Will they, however, decrease far enough to compensate for the lost fuel economy?
  4. According to the federal government’s alternative fuels locator, there were 2,386 stations selling E85 in the United States in 2014, with the majority of them located in the Corn Belt states of the Midwest.
  5. We had to go 130 miles to reach the only E85 station in our state at the time of the test, which was located in another state.
  6. Furthermore, we might see a situation in which increased E85 demand not only puts upward pressure on E85 costs, but also tempts oil firms to lower gasoline prices in order to compete, ultimately pushing the public back to fossil fuels.
  7. While it may be a component of a solution, it is definitely not a panacea in and of itself.

Flex-fuel Vehicles

Automobiles built to operate on gasoline or gasoline-ethanol mixtures containing up to 85 percent ethanol are known as flexible fuel vehicles (FFVs) (E85). A few engine and fuel system tweaks distinguish them from the gasoline-only variants, but otherwise they are similar. When running on E85, FFVs incur no degradation in performance, and some even generate more torque and horsepower than when running on gasoline. However, because ethanol has less energy per volume than gasoline, fuel-efficient vehicles (FFVs) usually obtain 15 percent to 27 percent fewer miles per gallon while running on E85 gasoline.

2 Locate Vehicles that Run on Flexible Fuel. FFVs have been in production since the 1990s, and there are presently more than one hundred different models available. Due to the fact that FFVs look identical to gasoline-only vehicles, it is possible that you are driving an FFV without realizing it.

Do You Have a Flex-Fuel Vehicle?

As of model year 2008, the majority of manufacturers began installing yellow gas caps on FFVs (2006 for General Motors). Some capless gasoline fillers include a yellow ring around the area where the fuel nozzle is inserted to indicate that the filler is capless.

Check the Fuel Door

Some FFVs include labels on the fuel door that indicate the type of fuel being used.

Check Your Owner’s Manual

The type of gasoline that can be used in your vehicle is normally specified in the owner’s handbook. You may be able to find an owner’s handbook on the manufacturer’s website if you don’t already have one.

Look for Badges on Your Vehicle’s Body

If your vehicle has a badge that says “E85,” “Flex-Fuel,” or “FFV,” it may suggest that it is capable of running on E85.

More Information

Stations that sell E85 provide information on fuel economy for FFVs (Alternative Fuels Data Center) Calculator for the Cost of Flexible Fuel (compare costs for operating your vehicle on gasoline and E85) Take a look at the data sources.

  1. According to ASTM Standard D5798-11, “Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines,” ASTM International, West Conshohocken, PA, 2003, DOI: 10.1520/D5798-11, the fuel economy difference between using E85 and gasoline is presented as a range because it depends on the ethanol blend and the vehicle: “The fuel economy difference between using E85 and gasoline is presented as a range
  • It is estimated that a 51 percent ethanol mix will result in a 15 percent reduction in mileage per gallon of gasoline, based on the difference in energy content between 51 percent ethanol and gasoline, which is normally 10 percent ethanol. On the other hand, the upper bound (a 27 percent reduction in fuel economy) is based on the difference in official EPA fuel economy testing of recent-model FFVs operating on E85 against those operating on regular gasoline.
