Gas type for better gas mileage?

E85 is very low energy which means you burn a lot to go the same distance as you would with gasoline. Use E10 gas unless you can get 100% gasoline.

Don't use E85, your mileage will suffer, as FOR said. Don't use any grade other than regular, you won't benefit as you vehicle required 87 octane. I've used regular non-ethonol gasoline and the MPG's will increase slightly, but not worth the additional price per gallon.

Thank you both so much for your insight, I truly appreciate it!!!
