Hello Chris, Generally, engines with compression ratios of 9.3 : 1 or less will safely operate with unleaded 87 octane fuel. Engines with higher compression ratios usually require higher octane fuels. Only engines with high compression ratios can deliver all the potential energy from higher octane fuels! Always consult the manufacturer's octane recommendation to determine the proper octane requirements for any given vehicle.

For vehicles that require a minimum of 87 octane, running regular unleaded all the time is recommended. The engine and on-board computer have been configured to achieve the best performance and fuel economy with regular unleaded in the tank. Putting in a higher octane fuel will not damage the vehicle, but the vehicle will not know how to handle the additional octane. There will be no performance boost from running premium fuel in a vehicle that only requires regular octane fuel. On the flip side, if a vehicle requires premium fuel, then put premium fuel in it. Certain turbo engines, and many high-performance engines require the extra octane to achieve peak performance. For brief periods of time, a lesser octane can be used, but the system will cut performance and not run well while doing so. Fuel economy also may suffer when running regular unleaded in a premium-only vehicle. Some vehicles have the ability to adapt extremely-well to what fuel is in the system. If the computer senses 87 octane, the car programs itself for the best performance with that fuel. If it senses 93, it will adapt to that. In those unique situations, running the higher octane usually means more horsepower and torque. Once again, your owners manual will provide the recommended fuel requirements for your vehicle.

Except for a few engine and fuel system modifications, they are identical to gasoline-only models. Once again, your owners manual will provide the recommended fuel requirements for your vehicle.

Hello FTHUNTER1983. See your owners manual (pages 238-241) for all the details concerning your fuel system. To achieve the type of mileage you achieved during your Arkansas trip would be very difficult in a normal stop and go city commute. To determine your mileage, the next time you fill up your tank note the vehicle's mileage. Consume roughly 1/2 of a tank of fuel and then fill it up again. Note the mileage and the quantity of fuel needed to top up the tank and divide distance traveled by gallons consumed to get your miles per gallon calculation.

The 2012 Impala comes in three trim levels: LS, LT, and LTZ. All trims include a new E85- capable, 302-hp, direct-injected 3.6-liter V6 engine and a new six-speed automatic transmission. The E-85 3.6-liter V6 is a flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) which is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank. Consult your owners manual for more details on fuel selections.
