E85 in a regular engine

Answer 1

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.
