I got E-10 woes with "Charlotte"- water in gas and looking for a permanent fix!

Michigan had a few places back in the 90s when I lived there { the cheapo places } that had that 10%-15% mix in the gas and to their credit they displayed it at the pump , my ex would think she was being smart and saving a couple of bucks to spend at the mall by not listening to me and filling up there , till I made her pay the 250 bucks to get the carb in my caddie rebuilt and my fuel system flushed for the second time in as many years then it started to sink in to her thick skull -don't burn modern garbage gas in an older car that the fuel was never made to be burned in
