for those of you who care, and those who cant afford the alcohol/water injection,or those who simpley dont want to put that on their car. I personally got more milage from a tank of fuel by using acetone (pure). yes the stuff you find in the paint section of your store or my favorite in the cosmetics isle. the bottles are easier to deal with. I have traveled all over the united states with this trick. I use 2.5 oz of acetone per 10 gal of gas/diesel. rember that most fuels are slightly different and this formula might take some tweaking to make it work best for you.
I am not trying to sell anything, nor am I a chemical engineer, this is something that I read on the internet and tried for myself. I just want to give something back to the community that has shared so much knowledge with me.
Oh yea you can expect an average of 15-20% increase in your milage.
