That's what was going through my head, but I didn't want to ruffle the feathers of participants in this thread who may be more volatile than, say, butane. Wait, y'mean the hygroscopicity of ethanol has to be factored in? Hey! Who the hell do you think you are, telling the landscaper guy he can't decide himself into a fuel formulation expert?! Perhaps you will have better luck, but I tried that right-tool-for-the-job line of argument right here in this very thread and it didn't get much traction with those who are bound 'n' determined to believe in the use of 2-cycle oil as a gasoline additive to ameliorate the bad effects of ethanol.
