Not recommended. E85 (flex fuel) engines are modified engines that allows the use of flex fuel. E85 is less potent then standard gas so more fuel (up to 34%) is needed to be injected into the cylinders to retain the car's power. Flex fuel cars have electronic fuel injectors, that can sense the E85 gasoline and increase the amount injected into the chamber. If you put E85 fuel into a standard engine, u will experience a significant reduction in power, and possibly doing harm to your engine. E85 fuel is good in a since that it burns cleaner and emits less emissions but because more fuel is needed to be injected, it produces lower fuel economy numbers.

No , the engines are not designed to use e85 in a 1971 Ford F-150

E85 is manufacture by the petroleum (oil) industry by combine standard 85 octane gasoline with ethanol alcohol. The mixture for E85 is approximately 85% Ethanol Alcohol and 15% standard 85 octane gasoline.

Hi, I'll weigh in on what I know. E85 can be run on engins that are set up for it and some early GM engines are able to as well as the new Flex Fuel vehicles are but our engines are Suzuki engines and as fafr as I know and have read, are not able to. I don't know what would happen if we tried to run E85 in our engines. Does anyone have any info as to what would happen if we did run E85? I hope someone will chime in on this. Thanks, Steve H.

not typically, temperatures that's are too low cause e85 to become more viscous, but in general no. I have a 99 ss camaro that runs e85
