Aftermarket Conversions of Vehicles to Use E85 Fuels
General Motors has become aware of several companies that claim to be able to convert vehicles equipped with gasoline engines to be compatible with
E85 Fuels.
Vehicles certified by GM as being FlexFuel (E85) compatible contain numerous calibration and component differences that are not conducive to an
aftermarket retrofit.
General Motors DOES NOT support or endorse conversions that may alter the emissions and related emissions components of its vehicles.
Repairs that may result from changes to GM built components and repairs that result from the use of improper fuel such as the use of gasoline containing
more than 10% Ethanol in a non-FlexFuel certified vehicle are not covered under the terms of the New Vehicle Warranty.
E85 Compatible Vehicles
The only E85 compatible vehicles produced by General Motors are shown above.
