Normal 87 Octane will work in anything, unless your engine specifically calls for higher Octane. The Division Bell between ethanol gas and non-ethanol is if the engine is not run often and the gas sits in tanks and fuel lines for long periods. If you're headed from NY to California, use 87 octane at any pump. If you're putting her away for the winter, either crank it and run it every month for a few minutes or fill it with non-ethanol. But you still need to crank it occasionally. Non-Ethanol Gasoline is very difficult to find and usually costs $1.50 more per gallon than normal, every-day 87 octane gas.

That is not correct. E85 is FlexFuel that had 50 - 85% Ethanol!!!!! It does not mean 85 Octane.

It is designed for vehicles that specify use of FlexFuel. Their computers can change the fuel and air requirements for regular gas versus heavy ethanol fuels. Chevy and Ford have some limited vehicles that use FlexFuel.

There is now 88 Octane fuels that are up to 15% Ethanol and can be used in most newer vehicles that run E0 (no ethanol) to E10 (up to 10% ethanol) gasoline.

Do not use E85 in any vehicle that does not say FlexFuel capable on the gas cap!!!!! If you do, you will be getting towed and end up with a very expensive service bill for flushing and servicing the fuel system.
