Busting Ethanol Fuel Myths | West Marine

Being a highly cynical person I see some corporatist propaganda in the above article. In this day and age it is hard to see where the government stops and corporations start. In any case letting fuel sit in a vehicle has always been a bad idea. I have always used E-10 in my lawn mower etc. without problems but that is just luck I suspect. That said I don't see any good alternatives. Unless you can completely drain the entire fuel system not just the fuel tank you are at risk of clogged jets and other problems.
