Flex-Fuel Vehicles: A Quick Guide to Everything You Need to Know
The 1990s saw the rise in popularity of automobiles that are capable of operating on flexible fuel, which is a mixture of gasoline and ethanol and is also known as “flex-fuel.” In response to this demand, automakers began developing entirely new automobiles that were suitable for use with this particular biofuel blend. However, many drivers are not familiar with the ethanol-blended gasoline that is sold under the designation E85 at petrol stations.Even some people who possess flex-fuel vehicles, sometimes known as FFVs, have worries regarding mixtures of gasoline and ethanol. Continue reading if you want to find out more about flex-fuel and whether or not you can power your car with E85 or another type of blended gas.
What does “Flex Fuel” stand for?
Gasoline that has been altered by the addition of ethanol is an example of flexible fuel. This type of alternative fuel is produced locally and uses renewable resources. Ethanol is produced by fermenting a variety of plant materials, the most common of which is corn. Ethanol can be found in nearly all varieties of gasoline marketed in the United States. However, the E85 fuel used in FFVs contains 85 percent ethanol rather than 85 percent gasoline.
E85 is a gasoline-ethanol blend that can include anywhere from 51 percent to 85 percent ethanol, depending on the time of year and the geographic region in which the distributor is located. For instance, E85 that is offered during the winter months typically contains lower quantities of ethanol than it does during the warmer months. This is done to provide the vapor pressure necessary for starting the vehicle when the temperature is low.
Can My Car Use Flex Fuel?
Traditional gasoline and ethanol mixtures, such as E85, are used in the production of flex-fuel vehicles by their respective manufacturers. These vehicles are characterized by their ability to run on either gasoline or ethanol. If the back of the car has the words “Flex-Fuel,” “FFV,” or “E85,” this could be an indication that the vehicle is suitable for use with an alternative fuel. If the vehicle’s gas cap is yellow, this is a good sign that it is compatible with flex fuel. If the vehicle has a fuel filler that does not require a cap, the ability to use E85 will be indicated by the presence of a yellow ring around the hole where the nozzle is inserted.
In a car that can run on either gasoline or diesel, you can put any octane rating of fuel in the gas tank. In an FFV, the sensors determine whether the fuel being burned is 100 percent gasoline or 85 percent ethanol, and then make the appropriate adjustments for the best possible fuel injection and timing of combustion.
Putting E85 into a vehicle that was not manufactured to run on flexible fuel may cause damage. Always refer to the owner’s manual for your vehicle if you need specifics on the type of fuel to put in it.
Why Should I Use a Flex-Fuel Vehicle?
Flex-fuel burns cleaner than regular gasoline, hence proponents of greater ethanol-gasoline blends argue that this will result in reduced greenhouse gas emissions. Additionally, the usage of flex-fuel will lessen dependency on oil imported from other countries. Corn, a renewable crop that is farmed in the United States, is the primary ingredient in the production of ethanol.
E85 is an appealing alternative due to its competitive price per gallon, which is cheaper than that of normal gasoline. At present moment, the price of a gallon of E85 is $4.34, which is 68 cents less than the price of a gallon of standard unleaded gas according to the AAA national average gas price.
Flex Fuel Disadvantages
Although the price of a gallon of E85 is often lower than the price of a gallon of ordinary petrol, fuel-efficient vehicles that use the ethanol-gasoline blend have lower ratings for their fuel economy. The variation in mileage can be as high as twenty-five percent in some instances.
For instance, a 2022 Ford F150 Pickup 2WD FFV with a 3.3-liter 6-cylinder engine achieves a combined mileage rating of 21 miles per gallon when it is fueled by gasoline, but it achieves just 16 miles per gallon when it is fueled by E85. Most of the time, the reduced cost per gallon of E85 more than makes up for the decrease in mileage.
Access to E85 and FFV fuel
E85 flex-fuel is available at more than 4,200 petrol stations in the United States, mainly in corn-producing eastern and midwestern regions. Because E85-compatible vehicles can also run on regular fuel, you can find them all across the country.
Many flex-fuel vehicles are unknown to the general public. In 2017, at least 21 million FFVs were sold in the United States, according to the research and information company IHS Markit.
FFV offerings from manufacturers have dropped in recent years. Why? Because of a shift in carmaker incentives in favor of electric vehicle manufacturers.
For the 2022 model year, FFVs will be available from just Ford and GM. All but four of General Motors’ four 2022 models will be available only to fleet buyers as FFVs. That’s down from more than 80 different models from eight manufacturers, according to the Renewable Fuels Association, which were available to customers as recently as the model year 2015.
Frequently asked questions
Do flex-fuel vehicles have more problems?
Enhanced Capabilities and Performance Although some people may argue that employing an alternative fuel source can have a negative impact on a vehicle’s performance, the truth is that it can have the opposite effect. When utilizing E85 fuel, the performance of vehicles that can use a variety of fuels does not suffer. In point of fact, some even produce more torque and horsepower than others.
Is it possible to combine E85 and 87?
It shouldn’t be too much of an issue. The computer can make adjustments for any concentration of ethanol up to 85 percent. The majority of ordinary gas already contains approximately 10 percent or more ethanol, and combining the two will simply result in an increase in the ethanol concentration to a level that is somewhere between 10 percent and 85 percent.
How much additional horsepower may be gained by using E85?
The actual advantages of E85 stem from the fact that it has a higher-octane rating (up to 110, depending on ethanol content and quality). Because of this, you can reap some of the same benefits that are associated with employing methanol injection, which means that you can run more spark (if necessary) or boost. On a vehicle with a forced-induction system, this ordinarily equates to 25–50 or even more horsepower.
