I don't believe you are going to find that the extra miles will be worth it in fuel savings because if you pay an extra 10 cents for the pure gas and if that gives you a hopeful 2 mpg more fuel efficiency with a 20 gallon tank, that would take 2.22 gals you used to get that hopeful extra 2 mpg, so you are going backwards in your pocketbook. I based this on a 20 gal tank, and fuel economy of 16 mpg with ethanol and 18 mpg with pure gas which would give you an extra 40 miles per tank. Now, is it going to be better for your vehicle? Maybe so, providing you don't have a flex fuel vehicle and your vehicle runs poorly on ethanol gas. You will just have to weigh your options but I personally wouldn't drive an extra 20 miles in my vehicle for it. Now, if I were going that way, I might consider it but not just to fill up.

Thanks for the link to find Ethanol-free gas stations. There are only 4 in Macon GA, and none are on my side of town. I need to figure out if it is worth about a 20 mile round trip drive :-)
