I used 1 oz. of acetone per 5 gallons at fill-up, so 2 1/2 ounces in all, from the 2nd to the 10th tank of gas in my new 2005 elantra GT. Since I had no MPG base, I had no idea whether it increased MPG or not. I stopped using it (it's been 4 more tank fulls ) and have not noticed any difference in MPG.

If acetone is suppose to allow a more complete burning, I'm guessing I should have seen an increase/decrease somewhere.

I've got about 4k+ miles on the car. I'll start using it again after I get another couple k on the car. and see what happens.

Better hope the dealership doing warranty work does not detect acetone that has been used in your car. Acetone will eat any rubber/plastic/composite material completely. I suspect you will have issue in the future related to your experiment.
