Apparently adding Acetone to your fuel in very small quantities can improve fuel economy by up to 40%.

This is interesting, wonder why it hasn't been already added?

we look forward to your test results ;)
Can't we all run methanol instead? With big-ass superchargers:norty:
ncie reply monkey, ill post this on my works forum. :smile:
i was hoping for some opposite opinions to this.

Well, that link is a good article and also a sceptical view.
A friend of mine is a chemical engineer and works with petro-chemical products and adding additives to such. I asked him, and basically he is about to do a study on that, but his initial response is:
"I have a couple of hundred pages to go through regarding this, but for now:
To increase the vaporization of gasoline you have to make the gasoline matrix unstable and that is not a good idea, since this also makes the lighter components of gasoline vaporise. That is, you lose burn-value and your octane level drops and can lead to a knocking movement in the engine. Secondly, you can increase the gas build-up in the tank.
I have seen people put household ethanol in the tanks. That should do some improvement - but whether it is economically feasible I do not know."
Knocking in this case is not something you can feel, but is kinda like a badly-running engine, but at a much smaller scale. Vaporisation changes could cause the fuel to vaporise earlier and when put under pressure in the piston it would ignite earlier and thus cause the engine to run slightly inefficient. This could be an explanation of the drop in mpg some talk about.
acetone is a nasty solvent, might damage engine parts, could deposit water in the fuel pump, conceivably might help the petrol vapourise, but without a controlled test you're unlikely to know :) It will also strip paint and dissolve some plastics (note the comment about reports concerning the prius tank-membranes "reacting" with it) if you spill it.
Feel free to try, at least you're not thinking about buying some magic-ecomony-enhancer fluid for £10 per 50ml to make you car "go faster":lmfao:
like he said, alcohol isn't added for better efficiancy but to make the expensive petrol reserves last longer in countries that can't afford petrol but can afford to grow acres and acres of sugarcane to make ethanol. It also ups the octane rating, but causes a bit more stress on an unprepared engine as would be expected, and the car might not last as long.
we used to use lead to reduce knocking ... not a good idea in hindsight
just so you all know, I had no intention of trying this. Although I'm glad its stired up some debate/fact finding :)
if its too good to be true....
Untill this is proven one way or the other I think i will stick to regularly servicing and cleaning the engine
I've found that walking and buses are good for fuel economy, myself. ;)
My bicycle does about 10 miles per Mars bar, sometimes more, though i'm not sure how long I could keep it up for :narnar:

i think u may need to see a dr about that
