Who uses Acetone in their gas?

My g/f has acetone laying around, i poured some in a bowl.... and in an hour it dried up and turned into some sort of slick paper/plastic feeling stuff.... i would not put that stuff into my car... ive never heard of acetone doing anythign for cars besides tearing off paint... lol

I've used it in my 06 impreza for a little while. I got about 1-2 mpg better. I added 3 oz per 10 gallons of gas. It was just kind of a pain to add it when I filled up because I had to use a glass test tube thing to add it. I didn't really feel it was worth the trouble to add it to the tank. Haven't used it on my stang at all. Acetone is supposed to reduce emissions a lot as well.

Well if the train left Wash DC on 4PM thurs and had 100 miles to go until lunch, how many beers will Bill drink?

14 beers (light though hes watching his figure)

What the heck. I have 150k miles on my truck. I'll try it and let you know how good it is after 400 miles (next fill up). Gas is almost $3 a gallon here.

Well,
Looks like I got about 7% increase on 6 oz. of acetone in 23 gallons of gas.
I ussually get about 400 mile on a tank full. My last tank full was 428 miles. Trying again and then will experiment with less oz. per tank.

where are you getting the acetone? i found a gallon of it fot $25. anywhere have it cheaper?

I used it in my last tank, mainly cause we only have 91 octane around here. It seemed to give me a little more mpg. I had a question though. What are the long term use effects of using it? I know that it will not harm the fuel lines and such, but how clean does this stuff burn, if at all? Since it is basically a catalyst, does it mix with the gas completely? If it enhances the atomization of the fuel and increases the amount of fuel burned, how much of the acetone is actually being used up, and how much is just converted into some other useless substance? It's been more than 10 years since I was a chemistry major, but if the acetone isn't completed consumed itself, then what partial molecules are left behind? Is there a point when you have a buildup of something in your tank?

Sorry, but I'm an analyst by trade and majored in chemistry for two years. I think about crazy crap like this all the time. By the way, I picked up a half gallon or so at Wal-Mart in the paint section for a few bucks.

The acetone that your girlfriend is using for her nails also has other chemicals in it like perfumes and vitamins and ****.

The acetone you want to buy is the one that has the chemical written out in atomic form. You buy it in metal tins at hardware stores. It has to be pure Acetone.

I used it this past summer, and in one tank I roughly gained about an average of 25-40 extra miles on a tank. Then the bulb on the syringe I was using to pour it in the tank melted and I spilt it all over the place. Luckily nothing got on the paint of my car - but it did ruin my pants and shoes and put some decent holes in my driveway.

I think I'll start puting it back in the tank again to help cope with these gas prices..

lol They just showed a test on a carburated engine on Mythbusters using acetone and it didn't improve gas mileage at all.

Ok, I have an update. I filled up today, and here's my two pennies. I use the same station, same pump every time. I always run it till the pump quits, then I add a 1/4 gallon more. I figure that's the best way to consistently get an average. I do not exactly do city driving, but there's a lot of stop and go getting to and from work.

When I got the car I was getting just over 17mpg to and from work. I advanced the timing and run premium, and I was up to 18.5mpg or so. I then switched added the 3.73s and it went down a bit, cause I drive the crap out of it. After calming down a little and installing the Predator tune, I was consistently around 18-18.5mpg again. I added 3oz pure Acetone per ten gallons of 91 octane to the last two tanks of gas and I've gotten 19.25 and 19.17mpg. I tried not to change my driving habits at all for this test. That's an increase of roughly 1mpg. I did notice that I had been getting about 20 more miles out of a tank. I haven't tried this with highway driving yet.

I can't say that it's a huge improvment, but it saved me a gallon or so of gas. We'll go with 1 gallon saved per tank of gas. If I add 4oz of acetone to every tank of gas, I'll get 16 tanks from my 1/2 gallon of acetone. When premium is over $3 a gallon, say $3.15, and I only paid about $3.50 for this half gallon of acetone. I'll save an average of $47. That's the cost of a tank of gas right there. I'll run without it in the next tank, and see what happens.
