Have you had results with acetone.

Anyone who has used acetone mixture and has had success please list mixture, make and age of car.

Can't remember my mixture, pretty sure it was the suggested ratio. 1992 V6 auto Camry. I also had my coolant boil over for the first and only time.

I couldn't tell. The only difference was that it made my idle speed lower. No harm.

Did you stop using it then? Also what kind of increase did you see before and after.

[omgwtfbyobbq]

Yup, it was on a run up the Cajon pass, after that I refilled coolant and stoped using acetone, no more trouble for the rest of the summer. I saw a difference of 2-3mpg over my best trip mpg (~34mpg) up to that point. The trip was hwy with the same distance, same traffic, same weather, and 55mph cruise control. The only problem was I didn't get in enough runs to determine if it was a glitch or if the acetone actually doing something, I also had ~5 miles our of 50 that were street, which could've influenced the results. I've heard it leans out the engine, but that's just heresay until I brush up on my chem... You wouldn't happen to know if your oxygen sensor is titanium dioxide, or zirconium dioxide?

No I don't. I think it's probably zirconium.

3 oz per 10 G...'87 300ZX na...around a 20% gain...but some part of this was due to easier driving.

So how much would you quantify to easier driving and have you stopped using it since driving easier to see what increase you had?

[jamescartagena]

I use it for all three vehicles.

97 Ford F150 - 3 oz/10 gal
92 Saturn SL1 - Currently testing 3 oz/10 gal
03 Honda Odyssey - 2 oz/ 10 gal

All get about a 10% increase of fuel economy. I've started using it last year and have run through 2 1/2 gallons of it so far. Anyone who says it will hurt your engine I think either hasn't tried it or is listening to someone else. My truck has used most of the two gallons as I drove it the most until I got the Saturn. The wife drives the Honda so I put in acetone about every other tankful when I get around to it. All get a noticable increase in power as well. In my truck feels the most noticable, and the exhaust pipe no longer has any black soot in it. I wouldn't drive without it even if it didn't increase my mileage because the increase in power is that noticable to me.

It was inconclusive for me. without a scangauge It makes results very difficult.
