So where i live every gas station sells gas with 10% ethanol. But in the country cities out of town they don't. The closest station is about 20 miles away. If my car has a 12 gallon tank and i get 24 city/34 hwy (its all highway driving out there) Is it worth it to drive out there every time i need to fill up? Its around a 40 mile trip there and back. Im just wondering how much better the non ethanol gas is, and i've also heard its better for your engine. thanks
