Default Acetone used as a fuel additive

Have any of you out there used acetone as a fuel additive? Several posts down someone mentioned the use of Toluene as fuel system cleaner. While researching its usage I came across several articles explaining the advantages and disadvantages of Acetone usage in gasoline engines.

I am wondering if anyone has first hand experience with acetone and is willing to share.

Thanks,

Jeff

I think that stuff burns too hot. you will shorten your engine's lifetime. It's always a compromise between performance and service time.

Besides your CO is not gonna be good.

I haven't heard of that one ever. I wouldn't even think of adding that to my tank. I am hesitant to put anything but quality premium fuel in my A6 tank.

Thanks for the opinions guys, I was skeptical but thought what the hay, I'll see what others have to say.

Default RE: Acetone used as a fuel additive

Acetone in very small quantities will help a car that is running rough due to combustion deposits in the cylinders and injectors or getting a tank of bad gas. This is not something that you would do on a regular basis. Adding acetone to the gas will make it burn hotter than regular fuel and turn the carbon build up in your combustion chamber to a very fine white ash that easily exits the cumbustion system. It will also remove deposts that build up over time on your fuel injectors much better than an off the shelf fuel additive. I have read extensively on the subject and some people even suggest that the hotter gasses exiting your engine help clean buildup off of your catalytitc converter as well. The general rule is to add 2 oz. of pure acetone to 10 gals of gas - adding more will definitely cause you headaches. Diesel owners report much better results than regular gasoline engines, but that may be due to the fact that diesel is so much 'dirtier' than gasoline.

Again, this should only be done occasionally because over time acetone has an adverse effect on rubber seals and hoses in your fuel system - basically it will slowly dissolve the rubber and other rubberized plastic parts. The dissolved rubber then ends up back in your combustion chamber and will cause more buildup problems than you had in the first place.

If you choose to add the acetone to your tank, try to burn through the gas as fast as you can on the highway.

Toluene is a much more potent solvent with incredibly high VOC. It is used in the vulcanizing process of curing rubber and is also used to etch hypalon surfaces in preparation for bonding - such as on a 'rubber' raft like the kind that the Navy Seals use. It's primary function is to dissolve rubber in order to react with other solvents to form a bond - something you do not want going on in your fuel system.

I'd like to bring this thread back for a bit. Has anyone tried this themselves? I've never heard of this but am interested in the effect of increasing combustion temps

might maybe work for a while,. but remember what sasquatch said.. you fuel system was not built to handle acetone or alcohol. so you'll ruin the rubber in no time...

If you're looking for a factory tested & approved fuel additive for an Audi, look no further that your local dealership. VW/Audi currently offers 2 different gasoline additives for these cars...one is an intensive F.I. cleaner and the other is a preventative maintanence dose. They're not too expensive and they won't void any applicable factory warranty when used as recommended.

Sure.....

ZVW239003 - "Gasoline Additive" 192ml bottle - msrp $4.25
This is the factory recommended maintanence dose that's been around for years. I use this stuff at least once a month.

and

G001770A2 - "Multipurpose Additive for Petrol" 90ml can w/spout - msrp $8.00
This is the intensive cleaner recommended for the alleviation of fuel quaility issues on newer FSI engines, but it can be used in non-FSI cars as well.

I've never used BG 44K in a VW or Audi, nor have I ever seen any side-by-side comparisons...but the "Gasoline Additive" is probably more comparible to Chevron Techron in that it significantly reduces deposit accumulation. I've also used it repeatedly in my 300k+ mile Volvo and the tops of intake valves were always sparkly clean.

The main attribute of acetone is the ability to dramatically reduce the surfice tention of the gasoline - the result should be better vaporization and completeness of the fuel-air mixing->enhancing the burning efficiency.
As many sourses point - not all acetone is created equal - the best should be some brand used in Beauty salons.
I periodically run acetyone (as only additive) in my cars - no adverse effect, neither any benefits.
I tend to assume I have not found the correct acetone yet...

My home blend (based on the ingredients found in LubroMoly, WD40 and Seafoam) is:

kerosene -30%
naphtha -30%
mineral spirits -30%
toluene-xylene-acetone -10%

Thats the best explanation I've heard for using acetone. You mix up a home blend, how interesting. What other spirits have a surface tension reducing property?
