OK, added acetone when I filled tank this afternoon. Concentration is about 2.55 oz/10 gal or 0.20%. This is based on full tank and filler tube capacity of 23.5 gallons. So, concentration not exactly known, but close. My last tank was 18.30 mpg of mixed driving in St. Louis area where all gas has about 10% ethanol. Until I fill it again, my driving habits will be the same; i.e., no long highway trips during the next week. I'll report back on this in about 7 or 8 days, hopefully longer. I'm not going to expect any performance difference so I won't be "Looking" for that. Just MPG. I'm well versed in statistical methods, so this test will not be based on one tank of gas.
