Acetone

This was brought up in a discussion group and I wondered if anyone here had any thoughts or intelligent comment .....:tumble:

 

Seriously some of the stuff on the site is BS but I know a couple of guys who have tried it, and whilst nowhere near replicating the claims, say they have seen better consumption.

Very interesting link.

 

Good find Terry :D

 

I remember older experiments with acetone and napthaline in fuel, for different reasons though. It was before the internet era, and can't remember much

 

Reducing the surface tension of the fuel, interesting idea, I wonder how relevant it is in something that evaporates as easily as petrol...(the 20mpg increase [bottom of the page] is a bit pushing it though...)

Terry, I used to use Acetone in my mix as a binder for the toluene and mtbe. Substituted it for Xylene, but I can't remember the reason now. Acetone in itself is about 120RON iirc and in itself is an excellent injector cleaner, but is also an effective degreaser which may cause problems with lubrication, especially if borewashing.

My biggest issue would be with the acetone reacting with other substances in the the fuel, mainly suspended lubricants.

 

I wouldn't mind if it was injected under boost or such, because then most of the time it would be outside the loop. But having it all the time in the whole system might create problems with the injectors or the pump perhaps...

...Needs some further compatibility testing to be safe®

where do u reckon i could get this stuff from??

 

Acetone is one of the major ingrediants in some nailvarnish removers :)

 

Please don't put nailvarnish remover in your car, or you'll end up with soft cuticles ....... ;)

John could you not add uplon or similar to compensate?

I don't know if it would compensate or they would neutralise each other. Needs R&D.

People use tiny amounts of it (1 quart of Klotz Uplon in 55 gallons of Meth) with methanol injection, but that is only used under boost

Hmmmm. Acetone wouldn't put that anywhere near my car. I work with it everyday at work. Have you not thought bout IPA, I used this before to give me a boost. Got it a work in 5 litre containers.

 

I work on a chemical factory which produces acetone and I agree with the above, wouldn't put it near my car either. Just my two penny's worth.

I've been looking into this further and I've decided to give it a try, 40cc in a tank should be safe I'd hope.

There is quite some room for improvement when it comes to 100%atomisation. Hell, even 'advanced' fuel injected engines like the 2JZ need coolant paths through the intake manifold.

 

I thought that the rushing/chopping action of the compressors, the deliberate swirl and quench zones would be enough to atomize the lot in a hot engine like this one --- but going carefully through books and papers it looks like we're not there yet.

 

It would be interesting to see if acetone really does the trick, as this guy claims

i just checked how much 3 fluid ounces was and got this from google ( i know the americans like to be different)

 

3 US fluid ounces = 88.7205891 cc

1 US fluid ounce = 29.5735297 cc

70 litres = 18.4920436 US gallons

 

 

So 88 CC's per ten gallons max!! im not sure 40cc in a tank will make any difference as it will be under even 1 oz per 10 gallons.

 

So if working to 70cc per 10 gallons (safety margin). you'd need around 126cc for a full tank. Have i cocked up my maths somewhere?!?

i aint puttin nail polish remover in my engine :D plus its fragranced, least youll smell nice going down the road :D

 

Im bout to pop down my B&Q see if they got it in there. Im wondering how much of a difference we will actually see as our petrol is of a higher rating. Im filling up with £20 which is 5.8 gallon at current price so im going to put in 40cc of Acetone. After all prob be a couple gallons at least in tank when i fill up.

After all the hunting found somewhere i can buy it from

 

http://www.nsinails.co.uk/content/prepassortedliquidproduct

 

(top of list) no i wont explain how i found this site :D

 

After more calculations....it is infact 3oz (89cc) = 8.33 UK gallons (americans is 3.75 litres to gallon whilst we are 4.5 litres)

 

8.33 gallons is 37.485 litres

 

So then you do 89cc (80 in this case for safety margin) / 37.485 = 2.14cc

 

So now whenever you fill up, just note amount of litres pull up to air pump area and put in the required amount of Acetone.

 

Also 500ml of Acetone will roughly do a little more then 3 whole tanks of fuel (based on 70litre) So an extra £1 a tank to try it out.

Just out of interest anyone here ever done an LPG conversion? I was wondering if the LPG system could be configured to deliver a measured amount of acetone into the fuel, so instead of having a huge LPG tank you would have a small acetone tank drip feeding in. I think that LPG links into the cars ECU as well, so it would be a really controlled system. Just a thought...

i remember seeing one supra for sale which had an LPG done but at end of day the boot is small and on the TT ones anyway may be bit more risky.

 

The amounts of Acetone going in to the fuel system here must be close in ratio terms of 1:300 - 1:400. Im not sure you would be able to control that enough. Plus a LPG system is only on when selected instead of petrol.

 

Im doing this as a test after reading up on it abit as long as i keep between 2 - 3 oz per 10 gallons i should be fine. Im an NA as well so if it gets my mpg up to 30mpg ill be impressed (which will be a 25% increase) they say they've had 40% ....im calling BS on that stat lol

No No No, dont do it :thumbdown ACETONE will break up the oil particles, it is an extremely good solvent. It has a double bonded oxygen which has spare electrons for bonding, so it likes to jump in between the huge hydrocarbon chains what we call oil. I used all the time when I was working up experiments, as it is a perfect solvent for seperating emulsions, mixtures. So as everyone else is saying do not do it!

 

If you are trying to go faster, or clean the system, you would be better to buy kerrosene (paraffin). Check on the side of any injector, octane booster and the main constituent will be that. I might get my PHd buddy to run some octane boster through a mass spec, so I can get the ingredients to make it myself. If there is anything silly or new to try at work, I am the one who always gets asked to do it!
