I used acetone in my gas, the results are in Options

about a week ago I put about 5oz of acetone into my Jetta's gas tank. this thread The tank was about 80-85% full at the time. I drove normaly like I always do. Here are the results...

99.5 Jetta GLS 5spd 70K miles

I usually get about 24-27mpg
with acetone added - I got 30.43mpg

I usually get about 310-330 miles to a full tank of gas
with acetone added - I got 372 miles <-- record high in the Jetta

It definatly increased my mileage. As for performance, it does feel better (quicker, smoother) but it is hard for me to tell because I switch from the Jetta to the Celica, and the Jetta is faster than the Celica anyway. But, in my opinion, the Jetta was more responsive than usuall.

the next step is using it in the Celica. I am filling up tonight and I am going to put in about 6oz (4-5oz per 10 gallons). I usually fill up every 10 days (430-440 miles) in the Celica. I am wicked excited to see the results with the Celica.

bottom line, this stuff works. If you are sceptical, google "acetone car" or something and read what others say and their results. Research it first. I did.

I got a 32oz cont of acetone at my local Ace Hardware store for $5.99. BTW, this stuff is used for stripping paint, do not spill it on your car. Use a long funnel to pour in.

I'm glad you asked that Art, results are still pending for the Celica but with the Jetta...
cheaper with acetone

$6 for 32oz

each full tank gets 6oz = $1.13 worth of acetone (about $.09 per gal)
1 gallon of gas = $2.39 *89 grade (about 24-27 miles for me) full tank (12.5) 2.39 X 12.5 = $29.88
$29.88 + $1.13 = $31.01 (full with acetone 372 miles)

to go 40 more miles with the Jetta I would need to put in about 1.6 gallons of gas or $3.82 to get the same as $1.13 of acetone.

$29.88 + $3.82 = $33.70 (full with gas + 1.6 gal of gas to get 372 miles)

not crazy savings but still savings. By the summer I will be paying $2.50+ per gallon of gas and I don't see acetone going up in price. I could probably get it cheaper at Home Depot too.
