Using any octane level of gasoline in a flex-fuel vehicle is acceptable. The sensors in an FFV detect whether the fuel is pure gasoline or 85\% ethanol and make necessary changes for optimal fuel injection and timing of combustion. Putting E85 in a car not designed for flexible fuel can be harmful.
Can you run 93 octane in a flex fuel vehicle?
– A FlexFuel system informs the ECU (engine control unit) through an ethanol content sensor and electronics, that measure the actual content of Ethanol in the fuel system. This systems allows the vehicle to be “flexible” in terms of what fuel it can run, either pump gas 91-93 octane to E85 or any percentage in between.
What kind of gas can I put in a flex-fuel vehicle?
The benefit of a modern flex-fuel vehicle, though, is that you can use any combination of gasoline and ethanol, whether it’s 100 percent unleaded gas or 85 percent ethanol. Your vehicle’s sensors will detect the blend and make the necessary changes.
What does higher octane gas do?
Higher octane allows engines to have higher compression ratios (for a more energetic explosion), more advanced ignition timing or forced-air induction like turbochargers or superchargers. It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
Can a flex-fuel vehicle use gasoline?
Is it better to use 87 octane or regular gas?
But if the vehicle manufacturer says your engine needs only 87-octane regular, that is what you should use. The higher octane of premium gas won’t make your car faster; in fact, the opposite is possible because higher-octane fuel technically has less energy than lower-octane fuel.

Do flex-fuel vehicles lose performance using E85 fuel?
While some might argue that using an alternative fuel source can negatively impact a vehicle’s performance, in reality it can have the opposite effect. Flex-fuel vehicles don’t experience a loss in performance when using E85 fuel. In fact, some even generate increased torque and horsepower.
