I just did the test with my 1992 Buick Roadmaster 350 TBI I have had the car for two years and drove it to FL 3 times and the best gas mileage I have ever got was 504 to the tank and it took 19.5 gal of gas. On the was down to FL this time I got 490 on my best tank and it took 19.2 gal of gas and there was little to no traffic the hole run. On the way home I used 2oz of acetone and my first tank I got 514 on the tank and the gas lite was not on yet I still had to get gas not wanting to run out the car only took 18.8 gal. on the next tank with another 2oz we raced a Ranger blew him away and my wife said the car never felt that fast I did not even tell her about the acetone we went 535 to the tank and again no fuel light the car took only 19.2 gal.
After this I am 100% sure acetone works in my car I don't car what kind of formula you have that says it will not work I know for a fact that it does.
