guys ive been putting 3oz of acetone per 10 gal ...(from home depot..a gallon is like $3.00)
into my tank for a few months now.
..actually all summer..3oz per 10 gallon my truck holds 25 gallons... so i fill up an 8oz soda bottle and dump it in then fill er up..
...its a 305 gmc 96 model throttle body with the performance chip..
..its a 5 spd and i tow the race car to the track with it.. when i dont put the acetone in the truck it will ping like crazy while tryin to back up or go up a grade from a stop w/ the trailer. 5spd
i dont notice to much of a performance gain.
not sure if its seat of the pants or my imagination..
the truck does tend to idle about 2/300 rpm higher and i saw about 18/25 additional miles per tank full. about the equivalent of running the truck with out a/c..
its more noticable when i dont put it in the tank.
cheap
