It's funny, I get the exact same feeling from you when you ramble on about new American cars being fine, when I'm saying that European and Japanese ones of even very recent vintage are in some cases NOT fine at all, and that virtually all vehicles that are much more than 5-10 years old have very legitimate concerns regardless of where they were made. No shit American cars are mostly fine, it's one of the few jurisdictions in the world where nearly all of the gasoline supply has ethanol in it, because of a huge corn lobby. That's not the case for the Euros or Japanese, hence why they've been slower to make sure all of their vehicles will be fine with ethanol. I mean shit, you even got confused about the environmental concerns about ethanol I raised, and seemed to think I was implying that different types of ethanol are better or worse for engines and fuel systems.
Whatever man, I'm not saying that ethanol as a whole is good or bad. I'm saying that there's valid concerns in particular cases in regards to damage to vehicles, and further, that not all ethanol is created equally in terms of environmental benefits/damages.
Carry on.
