HI!! Guys and gals, this is my first post, i have been surfing here on and off sucking up info, i 'm just trying this acetone out this week , the one think is add 1oz of xylene or xylol in with the 3oz of acetone , for best results so far i have some results but to early to too give the total benefit, i have only driven a half tank and i have seen results considering it was windy -7c today, and i was driving between 60-75 mph , i have an 01 Subaru Forester 2.5L 5-speed 196k,KMS., with cargo carrier on top and carry tools and boxes of cable etc ,cause i work out of my subie,Yes i know what your thinking, i have kept track of what my vehicle normally gets, and right know i'm at 321kms at 1/2 a tank ,my tank is 60l or 13.2 imp. gals., the bottom half of tank probably won't get as good from my experience. I also want add 1 oz, of syn. 2 stroke oil with the mixture to help lubricate.
