E15 is the most tested fuel in the market today. In fact, consumers have driven over 6 billion miles using E15 without a single reported negative effect! And ethanol burns at a lower temperature, which is good for your engine.
Higher blends can be used in FlexFuel engines. Not sure you have a FlexFuel engine? If you see a yellow gas cap marked E85 compatible, you should be good to go. Still not sure? Check out the e85 vehicle list below or enter your vehicle’s make and model here: https://afdc.energy.gov/vehicles/search/
Ethanol is a renewable, plant-based fuel. Most ethanol is currently made in the United States from field corn (not the sweet corn we eat). Ethanol sold at Iowa gas stations is grown by Iowa farmers and refined at Iowa ethanol refineries. Ethanol naturally has a higher octane level, which helps it burn cleaner than regular gasoline.
Ethanol production has decreased its carbon footprint while increasing its energy efficiency, creating a greener and cleaner fuel. It also replaces toxic chemicals in gasoline that have been known to cause cancer and smog. The production and use of corn ethanol decreases greenhouse gas emissions by an amount equivalent to removing 20 million cars from the road each year.
