cpurvis,
If you look in small gas engine manuals, they recommend ethanol gas minimum octane as do vehicles. They do not suggest using non-ethanol gas, this has been going on for many years now. Same goes for engine oil, my B&S Vanguard manual recommends using full Synthetic 5w-30, whereas most folks that do their own maintenance use least expensive conventional oil. In fact I believe most folks do not read their owner/operators manual regardless of dollars spent on new machine. Ethanol free gas is great to use in older hot rods, trucks, etc.
