A guy I know says he has runn it for 3 years in a Jeep Cherokee. Claims he gets something like 18-20 mpg vs the 14-16 he used to get. They go off-roading with them (Him and his wife have 2). Stock except the fuel I guess.

Now they are working on a conversion with a small diesel for one of them (I have to ask them at a GTG near me in July. They said they should have it done by then). I hope it is a 4bt cummins

Acetone is the most volatile and most easily combustible of all the solvent chemicals

Don't believe it?

Place a small open container - cereal bowl will do - of acetone outside in 80-90deg ambients, come back in an hour and measure any quantity of liquid left in the container.

Acetone readily evaporates at 70degF - fuel in your tank will nearly always be above ambient temps - the return fuel to your tank can be ~140degF.

Acetone added to the fuel tank will not be in solution for long at warm ambient temps and above - which means when you remove the fuel cap the vapors will no longer be barely combustible Diesel fuel, but highly combustible acetone vapors.

If the easily vaporized actetone is not in solution with the fuel, what possible effect could it have on the combustive quality of that fuel?

 

It worked pretty good in my 92 dakota (went from 400km to 500ish per tank), but as someone on the last page 20000+ psi ain't too shabby at it either.

 

My Advanced Auto Power Systems class did controlled Dyno testing with 2 engines . . . a Buick 3800 and a Cummins 24V. The dyno was programmed to simulate a light driving cycle based on throttle position percentage and varied through a series of rpm. The tests were run 3 times per group X 7 groups. Pne week was straight fuel and the next week was Acetone laced fuel. Fuel was mixed right before the lab was conducted to keep any variation out of the test.

Basically, the Acetone did nothing . . . the mass flow rate of fuel/hp was exactly the same or worse with acetone compared to the straight fuel.

The net semester class did the same tests with these:

We had our chemistry department do a mass spectroscopy on them . . . mothballs . . .
They did nothing for fuel mileage either.

Basically the gains that are seen by people when using these scams is likely related to driving habits.

If you put moose juice in your tank expecting to get better mileage, you will sub-consciously drive just a little bit nicer . . . thus bettering your economy . .

Just like a placebo drug.

Take care,

I did a very controlled test about 2 years ago with a car I was driving to and from work only. Same path, speeds and times of day etc. were kept to as close as possible conditions. I did this for 4 tanks of gas and each time I increased the amount of Acetone. After the 4th tank I saw ZERO gains in MPG. This was on a 2000 Pontiac GrandPrix. I still have the charts and stuff I did somewhere. In a gas engine I see no difference and just a bunch of BS. I bet the Acetone manufactures were loving it though!!

 

HUH?????????

 

I used to run it pretty religously at 3oz per 30+ gallons.

I keep good records on mileage and can't honestly say it helped, but too much HURT mileage in my early testing.

This thread ends THAT little goofiness!

Now I have pump concerns so 2 stroke oil/PS in ablend of 12/4oz will be used.

 

Lets see..Acetone is a pretty agressive solvent and fuel systems have some fairly sreious parts that don't like being dissolved.

Yup let's put a whole bunch inour tanks

 

Im on my third tank of using acetone, 2 ounces to 10 gallons of fuel, i have not checked my mileage yet but I do feel an increase in power. If that helps any.

 

Snake Oil plain and simple
Wont help anything that is needing lubrication in the fuel system.
Its a great degreaser and plastic dissolver,though.

 

TDR magazine had an article on fuel additives a few issues back. In the article there was a warning that acetone or alcohol will damage fuel system internals (seals for instance) and cause premature failure of components.
