Drive Flex Fuels
Choose Clean Air, High Performance, and Great Value

Flex fuels, like 88 Octane, are fuels for our future - Powerful, Clean and Green.

What are Flex Fuels?

Plants & fossil fuels in your tank.

Flex Fuels are clean-burning, 88-octane or higher fuels, like E85, derived from plants such as corn, barley and grasses. Most common is E15, which can be safely used in any vehicle 2001 or newer.

stations selling flex fuel are everywhere

Where can I buy them?

Everywhere. Everyday.

E10 is likely in your tank now. E15 (15% ethanol, 85% gasoline) is a higher octane fuel (88), proven to improve engine performance. E15 and E85 are now sold across the country as a popular alternative to gasoline.

My Gas Cap is Yellow!

You can fuel up with E85!

Fuel your FFV with E85 and you will reduce air pollution (nitrogen oxides, toxins and particulate matter) emitted by your vehicle. Compared to regular gasoline, greenhouse gas emissions are reduced by 34%.

flex fuels are the clean air choice

It is YOUR Choice

What's not to like?

Flex Fuel improves air quality for healthier living. It's local and renewable to support American workers. It burns clean and powerful for your car. It's NASCAR's choice - they've run 10 million miles to prove it!

Why should I choose Flex Fuels?


The U.S. ethanol industry supported the creation of over 386,700 jobs in all sectors of the economy last year, boosting household income by $30.7 billion.


Flex Fuels won’t harm groundwater in the event of a spill and are safer for drivers to handle. Ethanol cuts carbon pollution – reducing carbon monoxide, volatile organic compounds, nitrogen oxides, and particulate matter emissions up to 50% more than unleaded gas.


Using a higher level of ethanol fuel can increase horsepower and octane, reduce engine knocking and pinging, help clean your engine by reducing fuel injection system build up, and prevent gas line freezes in cold weather.


Fuels made from renewable plants are frequently lower in cost compared to petroleum. The more that is mixed with standard gasoline, the lower your gas prices are at the pump.


Today ethanol replaces about 10% of the nation’s gasoline supply, which would otherwise require 600,000 barrels of oil a day from unpredictable foreign countries and finite fossil fuel resources.


FFVs specifically designed to run on E85 (85% ethanol and 15% gasoline) fuel are becoming more common each model year. Drivers can choose to run their FFV on E85 or any lower blend of gas. There are more than 20 million FFVs on America's highways.

Busting Myths about Flex Fuels

Driving Flex Fuel is nothing new - it first powered an engine in 1826 and fueled Henry Ford’s Model T in 1908! Research has come a long way in developing viable alternatives to replace fossil fuel gasoline. Today, corn-based ethanol is the most common flex fuel. While in production for over four decades, ethanol still carries a lot of misconceptions.


The REAL Story: This only applies to fossil fuel, oil-based gasoline. Ethanol is produced from renewable plant matter - like corn, potatoes, and sugar cane - which grows through the use of energy provided by the sun. The U.S. Department of Energy’s Argonne Lab reports that for every unit of energy expended in gasoline production, just 0.81 units of energy are delivered in the final product. For every unit of energy used to make ethanol and its co-products, 1.87 units of energy are yielded.


The REAL Story: Actually the opposite is true - it can help lower prices by lowering gas rates and transportation costs. Only 3% of all food production costs are directly related to corn prices, so the savings are greatest by including a greater amount of ethanol in the fuel mix to lower prices.


The REAL Story: Corn grown for ethanol is a hard, dent corn that farmers allow to dry in the fields, not the sweet corn people eat. Today's ethanol production is about more than fuel. Approximately one third of every bushel of corn processed by an ethanol biorefinery returns to the livestock feed market in the form of a highly nutritious animal feed as distillers grains or corn gluten. Ethanol production also results in corn distillers oil and other bio-based chemicals to replace oil. Similar innovation is occurring on American farms. New farming technologies and increased efficiencies are resulting in record production every year.


The REAL Story: All small engine manufacturers in the United States approve the use of E10 (10 percent ethanol, 90 percent gasoline) in their equipment.


The REAL Story: According to Oklahoma State University, highly aromatic additives, like benzene used to increase octane, are more corrosive to plastic components than ethanol.


The REAL Story: Today’s fuel (ethanol enriched or not) has a short shelf life. Many manufacturers recommend storing fuel no longer than 30-60 days unless a stabilizer is used. After this point, gasoline starts producing gums and varnish in your fuel system, possibly harming the engine. Fuel containers should also be sealed to improve longevity.


The REAL Story: Ethanol is anhydrous. E10 fuel cannot absorb enough moisture from the air to cause phase separation (separation into two liquid phases). If water is allowed directly in the tank, phase separation can occur in both straight gasoline and ethanol blends.


The REAL Story: Ethanol provides high octane for exceptional engine performance and reduced emissions. Need proof? The National Boat Racing Association uses E10 exclusively for all their races.


The REAL Story: Internal testing must be completed before a manufacturer recommends using a specific fuel blend. Recognizing the fuel’s growing popularity, all small engine manufacturers have long permitted the use of E10. See your manual for more information.


The REAL Story: Ethanol is an effective solvent and can help remove gum and deposits left by years of gasoline use. This is one of the many reasons alcohol is often used as an additive in today’s fuel.


The REAL Story: Aromatics used in today’s gasoline are generally more aggressive to rubber than those of the 60s and 70s. Extended storage periods without proper treatment or overuse of certain additives may also contribute to deterioration of fuel system components.


The REAL Story: Ethanol is one of the most economical performance fuels on the market. That is why it is used by every car in NASCAR’s three premier series. Many teams have reported an increase in horsepower and no decrease in mileage when using ethanol-enhanced fuel.



"Recent research showed a 30% reduction in carbon dioxide emissions when using E85 compared with regular gasoline."

Argonne National Laboratory

"Motorized Vehicles are the #1 single largest source of air pollution. A Flex Fuel Vehicle driver can significantly reduce lifecycle carbon dioxide emissions from entering our air by simply fueling with E85 instead of gasoline."

American Lung Association

"The use of a 15% ethanol blend (E15) in all passenger vehicles model year 2001 and newer, as well as all FFVs is approved."

U.S. Environmental Protection Agency

"There is strong demand across the country for cleaner, more affordable fuel. We want to give consumers more affordable choices at the pump."
