Possible, but unlikely? The ratios (even at a very high 150 octane for acetone) likely add less than a point of octane. But maybe I could have used mid grade and noticed a mileage boost? Knock and pre-ignition was not present iirc, and sadly, the car is long gone. My evidence is all anecdotal, I do not have the logs anymore. It was a fun traffic carver, so small I could slice and dice thru traffic quite easily! The car was around 1500 pounds curb weight, and I got it for FREE. It needed a computer and I found one at the JY for $40, with a one-day warranty because it had a water stain on the back of the case. It was 2 generations removed from the model I had (but same year ) as they changed calibrations frequently then. But it WORKED and worked very well! I bought some tires and drove the snot out of it. Finally lost compression and I junked it, got more for it than I had invested

I also had a great time with my next ultra-cheapo car, a $400 Mister Two, first gen But that is another story!
