Letting a car sit until the E10 in it smells like crap will clog things up in a hurry. Drain that crap out and run 20 gallons of 93 octane Shell or a bottle of Techron through it if that happens. I experimented with E85 in the Saturn last year. This is a car that runs -10 to -15 fuel trim on E10. When I got up around 60% ethanol, assuming the E85 was really 85% (it probably wasn't) it started setting a check engine light from long term fuel trim getting over +25. (help, I keep adding fuel and the O2 sensor still claims it's lean). Noticed a little more power with the E50, but after the experiment was over I'm not sure it runs as well as it did before. Or maybe I got used to it running stronger the month it was a fuelie. That guy on Youtube, I think it's Practical Farmer, who does the silly oil tests? He did a silly gasoline test once. The part I didn't find silly was when he soaked some sooty head bolts from an old Briggs&Stratton in V+ Shell and it cleaned them up pretty well. Nice demonstration of what it's supposed to do to EGR sooted intake valves over time.
