'Mark Cooper's Report of Directory:Acetone as a Fuel Additive Effect on Mileage and Performance'


Two tanks in a row now at a consistent 20% increase over previous mileage for daily driving to and from work. This is a mix of city and hwy miles almost 50/50 of one another. About 30 miles on the way to work (dropping of a kid at school in the AM) and 28 on the way home, of the evening.

Have a neighbor with an 04 Dakota 4 door truck with the 4.7l in it. Have set him up with 3oz per 10 gallons and his first tank worked out to be 15.8 mpg. He said he never gets no more than 11.66 mpg. He's about to take a road trip to Orlando so we'll see how it does on the highway. We live about 2.5 hours north of Atlanta, so his trip will be long enough to deliver some good numbers. And he has a log where he's keeping up with it as he goes. Will report here with more as he gets back with me.

My last tank netted me 28.5 mpg for the avg of the tank just driving to work (about 50/50 city/hwy). My window sticker says I'm supposed to get 21/29 so I'm about on the money for highway mileage and that's the avg of both types. I was getting 23 for an avg of a tank before I started using acetone. I didn't have a lot of time in the car prior to acetone as I had just bought it before finding out about this acetone thing. Now I'm doing so well, I don't want to go back just to find out what it is without it (again). For two reasons, one, money (of course) and two, I don't want my motor getting all that carbon in it like it used to and as my previous vehicles have. OK. I feel a little guilty for not driving a Prius, but doing this makes me feel a whole lot better about it. -) I wonder how many others out there have neighbors trying it too now and we're not getting near the documentation we could be if we had results from all of those guys as well.

Vehicle Summary

make & model of car : 2005 VW Jetta GLI

ratio(s) of acetone used (oz / 10 gal) : sticking with 3 to 3.1 oz per 10 Gallons of 87 octane

mileage before : driving to work avg 23 MPG

mileage after : same trip 27.5 ~ 27.6 MPG

number of miles tested : 2,092 as of 5/11/2005

other observations (power, idle, exhaust) : power did get better, new car no diff in idle, exhaust is a bit "sweeter" smelling not like straight acetone is, but you can tell it has been treated with acetone once you know what acetone smells like.


These are observations I have made in making contact with people on the subject. Not so much about the vehicle or techincal items.

There are still so many people that I talk to at work who say they just may try it, but they continue to go along without, saying "they are waiting for my motor to fall out of my car". These are the same yahoo's who will drive out of their way for a little cheaper price per gallon at the pump?!?!?!? WTF? Come on. You could be getting cheaper at the pump everytime, not just "when you find it". Really wears me out. I'm amused by it actually. I'm thinking to myself, what a DA. Just more proof of fickle folks I reckon. :-)
