Regular unleaded gas will work just fine, bottle of fuel system cleaner once a month helps...

Make sure you vehicle was designed to run on ethanol based fuel, I'm not sure. If not, you may have to change a few hoses and fittings, as ethanol tends to damage rubber components not specifically designed for ethanol blends.

Rowefast wrote "Regular unleaded gas will work just fine" which is 100% right especially with a good fuel treatment, and OJ makes some good points about ethanol based fuels. Most fuels with ethanol contains 10% to 15% ethanol depending on your state. Premium gas can run .30 to .45 cents a gallon. Then again premium gas also burns cleaner and a gallon takes you a bit further compared to the cheap stuff. It doesn't hurt to run the premium gas about every one to two fill ups. I have noticed my valves will have a rattle (especially going up hill) if I don't use premium gas every two fill ups. Gone are the days where you could find just about anywhere 104 to 110 octane racing fuel.

All good points...but where I live, have no choice in fuel, either unleaded, or premium, so the car can run ethanol fuel as it is a 2010 impala, but my truck I have to run premium since it is a 1995 Chevy that I built a 400 hp motor that sits in it. I don't know, this ethanol stuff dose gum up injectors & carburetors on the older ones...premium all the time or unleaded with a gas treatment...

Rosenfast: If your 400 HP motor needs a little boost because of a higher compression ratio you should be able to pick up some 100 or 100+ octane fuel at a local small airport. Piston powered aircraft are still exempt from the ethanol route, I believe. But be careful. AvGas may still contain lead. If you have a cat converter you will really gum up the works. I use to use AvGas in my 63 Olds until I sold it.

Thanks for that OJ, headers and 3" exhaust, no cats. Also I put a octane boost additive in once in a while, motor has less than 5000 miles on it in three yrs. And our local air-port stop selling their fuel, but there is a place 70 miles from here, so not feasible unless there are bets...ha.ha.
