Your car, if standard is tuned to run on a minimum of 95 octane, but even standard it may have some knock retatrd happeing on this fuel, so if it is, your car will benefit from using a higher octane fuel. Using a higher octane fuel will eliminate or slow down some of the knock retatrd from happening, so the car will pick up some power. E85 does have a higher octane than 95 and even 98 fuels, but if standard, your car will not benefit using it over 98 as the 98 should pretty much stop all knock retatrd. Also the calorific value of E85 is less then PULP, so you will use a lot more fuel to do the same distance If tuning the car and using E85 you should pick up a little more power over other fuels because of the extra timing you can run, but this comes at a cost of having to use larger injectors and possibly larger fuel pump than you would need using PULP.
