You can put E85 fuel in your car only if it’s a flex-fuel vehicle (FFV) designed to handle high ethanol content safely. Using E85 in non-compatible cars can cause engine problems and void warranties. Check your owner’s manual, fuel door labels, or VIN to confirm if your vehicle supports E85 before filling up. If you want to understand the benefits, risks, and how to find E85 stations, there’s useful info ahead to help you decide.

What Is E85 Fuel and How Does It Work?

What exactly is E85 fuel, and how does it work in your car? E85 is a blend of 85% ethanol and 15% gasoline. Ethanol is an alcohol-based fuel made from plant materials like corn or sugarcane.

When you use E85, your engine burns this mixture instead of pure gasoline. Because ethanol contains oxygen, it helps your engine combust fuel more completely, which can reduce some emissions.

However, ethanol has less energy per gallon than gasoline, so your car might get slightly fewer miles per tank.

Your engine adjusts the fuel-air mixture to accommodate this blend, ensuring smooth operation.

Using E85 can be cleaner and renewable, but it requires your engine to handle the unique properties of ethanol fuel properly.
