What do I do if I accidentally use E85 in conventional car or diesel?

If you accidentally filled up with E85, don’t fret! While you may see the engine light turned on, you’ll generally be fine once the E85 works its way out of the fuel system. Otherwise, top the gas off with regular gasoline as the tank begins to empty out.

Can I convert to Flex Fuel Car?

We do not support the use of aftermarket conversion kits as the fuel systems of conventional vehicles are not compliant with E85. Even if these kits allow a traditional engine to run on E85, the vehicles could be impaired by long term incompatibility of the materials of the fuel system.

What is a Flex Fuel Vehicle?

Flex Fuel vehicles (FFV) are designed to run up to 85% ethanol (E85) on gasoline or gasoline-ethanol blends.
