Acetone added to the fuel....

[WMSmotorhead]

Check this out... This gent generally has videos about fun electronic projects, so I watch those, when this came up, it did get my attention.... Wanted to know what you thought of the Acetone idea.

KipKay's Increase your MPG

On a side-note, Justice Bros. Fuel System Cleaner REEKS of acetone, and I saw an MPG jump whenever I used it....

Not this again. Some things just never go away!

 

[Andy636]

I always use 5-10% pure acetone in my RC scale planes glow engines(nitromethane it's hard to come by here) and I always get a more stable idle at a bit lower RPM.

Acetone definitely improves mpg as long as you don't overdose with it.....here's proof...

I wouldn't do that. I could be wrong but I doubt acetone is very friendly to rubber

 

[A_Harman]

I also recollect that acetone is hard on rubber seals.

There are much more vicious chemicals than acetone in plain gasoline.
What keeps them and any bit of acetone in check is that they are so diluted.
Acetone is a good cleaner, and may somehow 'lie' to the O2 sensor.
Some really have had success with it in fuel.
I tried it and gave up on it - to much hassle and care of handling.

Going from memory (reading through countless MSDSs over the years), one doesn't find acetone added often to retail fuel additives, something I confirmed through a quick Google check. I assume there's a good reason for that...
Google "acetone fuel cleaner material safety data sheet".

Sounds like Berryman B12 Chemtool, with 65% toluene, and 25% acetone. Has a bit of methanol in there, too.

LOL, I hard it first in 2005-2006, tried in 2 cars, no difference whatsoever for me.

I actually researched it and gas should not contain more than 1% acetone. Small amounts should be absolutely harmless.

A few years ago a 4WD magazine tested a half dozen fuel saving ideas.Acetone was one that worked to a degree.The jeep that was being used as a test vehicle showed increased fuel mileage for 2-3 tanks which then tapered back down to the original test base mpg.

I think it had a better effect on carbed vehicles in the past.The acetone was said to lower surface tension which lead to better atomization of fuel.

I've used it on the order of MMO with comparable results.IIRC that was on a 89 Sidekick 4 cyl and a 82 Dodge slant six.

Are the run on water hydrogen generators coming back too?

 

[surfstar]

Of course it works - how do you think they got 200 mpg out of a carburetor?

 

[morris]

if i remember right hydrogen has the largest a/f range. i think from 4-6% to 400-600%. i think.

I'm bringing up this discussion because I'm interested in testing small amounts of acetone in my carby alfa romeo.

We have such bad fuel here imported from Brazil.
This year has been exceptionally bad.

I;m not interested in getting better mileage.
I'm more interested in improving the quality to avoid detonation and improve idling etc.

my car pings easily even with premium (name used very loosely!) with boosters but tests have revealed both fuels, super and premium, are of equally bad quality.

The boxer is very picky with the fuel and you feel and hear the difference.

But I'm very concerned about the acetone attacking carb parts (diaphragms, o-rings), electric fuel pumps and fuel lines etc.

Thinking of doing some lab tests with some old parts soaked in a mixture of acetone and fuel to see if anything is adversely affected.

Overdose the acetone, and you may indeed see problems.
Use normal dilutions, and you won't.
Try a little [in your situation] in your car.
It may help - don't count on it, and don't expect miracles.
Good luck!

Maybe 25ml per 10 gallon(45 litres) fill?

 

[dailydriver]

Does the same apply to Xylene and Tolulene;

i.e.; are they just as harmful/corrosive to everything as Acetone is in higher concentrations??

 

[Loobed]

I remember race car drivers adding acetone to their fuel to allow the high compression engines to start easier with high octane fuel. A lot of racers had an oil can filled with an acetone-gasoline mix that they squirted into the carb or FI intake just to get the engine started. After the engine was running it ran off of straight gasoline.

I read a thread on a guy trying acetone in his gas with a Saturn SL-2 for a number of tanks of gas; no MPG improvement but it cleaned his spark plugs.
