What we should all be hoping for is E85 capabilities, because that burns hotter than 93 and will give you some extra horses when using it.
wrong, e85 has less energy, it's ethanol based, you'll get worse mileage

you want to run the lowest octane fuel you can, without predetonation, any higher is a waste of money
