Acetone In Fuel Said to Increase Mileage 15-35% - Page 7 - PeachParts Mercedes-Benz Forum

tenknots · #91 04-05-2005, 07:39 AM

I filled up last night and went 336 miles/11.6 gallons = 28.3. Not bad, since I figured I must have underfilled for the last exceptional recording. This tank was the "purge" tankful - no acetone. The last tank that gave me such a good reading was the tankful after adding acetone that had a very diluted mixture.

Last night I added exactly 3 oz of acetone and the tank holds 22 gallons I believe. My next fill up will be Thursday or Friday since I'll probably work at home Wednesday. At that point I will fillup with diesel only and record. Then I'll try 2 oz of acetone, and a "flush tank", then 1 oz etc...

I need to get the experiment over with soon as warm weather is coming and I can't turn on the AC and still get valid results.

As far as adding, I found a plastic graduated cup that should last a few times. If I add the acetone then immediately fill up, I think the fill hose will be washed free of acetone. I then have a 30 mile drive home to get it mixed up before it sits overnight.

Note: when adding acetone, DO NOT use the little cups that come with Nyquil - they last about a nanosecond when filled with acetone.

I've found that a shot-glass works well

BTW .. If i can still do my math
10 gallons = 1280 fl oz
the recommended acetone dosing is
.03 to .20 of 1% by volume or
0.384 to 2.56 fl oz / 10 gallons fuel

Triff ..

rwt .. I'm giving this a go in a 1993 JGC

Some have tried it and posted the results near the end of this page;

Sigh,
the test does not go so well. 403 miles/13.2 gallons = 30.5 mpg. This with 3 oz of acetone at the last fill. Good, but hardly better than my normal. I never have gotten better than 30 mpg except once after the acetone test - see above. But 30.5 could be attributed to better traffic, lighter foot, summer diesel, etc. It ain't 15-35% better.

I'm curious to see what the next fill up gives me - the last time I got over 32 AFTER the acetone.

But the testing can't go on long - soon I'll need the AC on some days and I won't be able to duplicate my driving closely enough.

I'm starting to think WVO...

you can run another series of test with AC on. It may make a more marked improvment when the engine is more taxed. It may not too but..?

I think I'm finished with the testing. No matter what I do, I am always close to the mean MPG that I've been getting. Last time with acetone it was 30.5. Today, I put in 17.4 gallons for 508 miles = 29.2. This was without acetone and is within my normal range of 28.5 to 30 mpg. I had one anomaly that got me excited when I got over 32 AFTER the tankful of dieseltone. But the next tank brought the average back. At a 15% increase, I should see nearly 35 mpg - not going to happen.

I hearby officially state that adding acetone to increase mileage is a crock. At least in a 1981 Mercedes 300SD turbodiesel.

very good thread....I was thinking of adding this stuff but changed my mind

that the f1 cars of the thirties may have had acetone amongst the other seriously toxic things in the fuel. but of course they were designed for it. and though they definately werent diesels they were mbs.

Acetone added to fuel???

Awaiting more data; before it goes into my fuel tank...

Still trying to keep an open mind on this subject.

I looked I to this after seeing some articles on the internet. And I kept tracing the rumors, legends back to the same expert who indeed just happens to sell you a product for around $50 to prove the great gains you are getting by adding a small amount of acetone to each tank of gas. His gadget plugs into the diagnostic port on most cars manufactured after 1996. This device reads out your exact MPG at any given time so there is someone making a buck pushing this idea. I also found a user group that did some sound testing and found that on older cars using carburetors there was a significant increase in MPG. After running a few tanks with acetone in it discontinuing the acetone did not result in a loss of MPG from there studies they concluded, that the acetone was acting as a strong detergent and on older vehicles a few tank fills would indeed increase MPG but that after discontinuing the use of acetone it did not reduce the improved MPG. On newer fuel injected vehicles, they had no measurable increase in performance or fuel economy. We did a blind test in a 1985 300d NA 5 tanks had acetone in them 5 did not there was no discernable difference between the tanks with acetone and those with out in performance or MPG.

I still think its a nutty idea.

Yep, it seems like Star Trek with all the junk science that "explains" how it works.

#**103** 01-04-2006, 04:00 PM

No not a nutty idea truly brilliant one in my opinion. You come up with a great new product a device that plugs into the diagnostic port on all cars made after 1996. This device tells you your current actual MPG as well as trip mileage per gallon data. To make a great profit you need to have at least a thousand manufactured. You borrow from friends and relatives some prototypes are made then the big order for a thousand is placed in china. 6 months later, you have sold 7 and giving ten away. This guy is not a quitter so he exaggerates a new fuel additive with conspiracy stories of big oil keeping it from the public. Now it is the talk of the town if there were only some way to tell the actual real-time MPG as well as data by trip, time or between fill ups. Well guess what the biggest scientific backer of acetone in fuel as well as the guy spreading the news about the new amazing additive just so happens to sell the gizmo that proves it works. Nutty I think not if he now sells 30 a week, he is brilliant.

This reminds me of the Tornado fuel savers and the magnets you stick on your fuel lines.

According to the accepted definition, BRILLIANT!
