Re: Regular with up to 10% booze-a-haul, or high octane w/out?
Ask Brazil, they produce tons of Ethanol and most things run on an even higher content of ethanol. For a while, it was mandatory to have 25% ethanol. Engines can easily be made to do it, but I would prefer not to with our engines. They are already cheap engines, with cheap seals and gaskets, and are of cheap aluminium. The ethanol does not help this. It seems after I switched to pure gas, my crank seals haven't been wearing out anymore. I use 89 octane pure gas at stations I can find it, and the 93 premium pure gas at the other stations. I messed with the head and get pretty high compression, so I don't mind using the high octane, and when I get 125mpg, the cost difference is marginal.
