You can only put E85 fuel in your car if it’s a flexible-fuel vehicle (FFV) made to handle 85% ethanol safely. Using E85 in non-FFVs can cause engine problems and damage fuel system parts.
E85 fuel is a blend of 85% ethanol and 15% gasoline designed to power flexible-fuel vehicles (FFVs). When you use E85, your engine runs on a higher ethanol content, which burns cleaner than pure gasoline.
What Is E85 Fuel and How Does It Work
E85 fuel is a blend of 85% ethanol and 15% gasoline designed to power flexible-fuel vehicles (FFVs). When you use E85, your engine runs on a higher ethanol content, which burns cleaner than pure gasoline.
Ethanol is a renewable fuel made from plant materials, so it produces fewer greenhouse gas emissions. Your car’s engine control system automatically adjusts the fuel injection and ignition timing to accommodate the different combustion properties of E85.
Using E85 helps reduce dependence on fossil fuels while supporting agricultural industries that produce ethanol.

Because ethanol has a higher octane rating, E85 can improve engine performance and reduce knocking. However, ethanol contains less energy per gallon than gasoline, so your fuel economy may decrease slightly.

Which Cars Can Use E85 Fuel Safely
Using E85 helps reduce dependence on fossil fuels while supporting agricultural industries that produce ethanol.
If your vehicle is labeled as a flexible-fuel vehicle (FFV), you can use E85 fuel without worry. FFVs are designed with components that handle high ethanol content, ensuring your engine runs smoothly and efficiently on E85.
How Can You Tell If Your Car Is Flex-Fuel Compatible?
These vehicles adjust fuel delivery and timing automatically, preventing damage and maintaining performance. However, if your car isn’t an FFV, using E85 can cause engine problems, fuel system corrosion, and poor performance because standard engines aren’t built for such high ethanol levels.
Many newer models from manufacturers like Ford, Chevrolet, and Chrysler offer FFV versions, but not all vehicles qualify. To stay safe and protect your engine, only use E85 in cars made to handle it—otherwise, stick with regular gasoline or recommended fuel types.

Wondering how to know if your car can handle flex-fuel like E85?
First, check your owner’s manual—it usually states if your vehicle is flex-fuel compatible. Look for terms like “flex-fuel,” “FFV,” or “E85 compatible.”
If you’re still unsure, visit your car manufacturer’s website or enter your VIN on a reputable database to confirm.
You can also inspect the fuel filler cap or inside the fuel door; many flex-fuel vehicles display a yellow gas cap or a label indicating E85 compatibility.
