Acetone as a fuel additive

just started reading this now seems interesting, lemme know your thoughts guys, gonna keep reading and possibly try it , depending on what i learn from reading the rest

I also heard it eats/hardens the rubber compoents in your fuel lines over time.

Just like the fuel did when leaded fuel was replaced in the early 90's.

Fuel companys were putting all sorts of crap in the fuel they were blending.

it looks pretty promising, but it would be a pain in the arse to accuratly measure the correct amount of acetone to put in your tank

YOU CAN USE IT IN BIKES THAT HAVE CARB ICING PROBLEMS LIKE THE ZX9 C1 AND C2

Acetone was always a component of racing fuels,not for any benefits of it's own,but to help the mix of other components.The article said it reduced surface tension of molecules - so that sounds right.Acrilic laquer thinners is acetone,get it from an automotive paint shop.

In many hardware stores it's right beside kero, turps and meths.
I know HD riders put meths in their tanks.
Not too sure why they'd do that.

It's hygroscopic, blends with water in the tank, which is then burnt with the fuel.

Would meths/alcohol in the tank do the same thing as water or alcohol injection in the air intake? Cool the intake charge to allow greater timing advance before knocking starts and more dense intake charge. Since HD's have big cylinders they may be more prone to knocking like rotarys with their long narrow combution chanber. (Harleys and Rotors in the same line! Hope no-one puts a price on my head!)

Not really, but it would have the same effect as using a higher octane fuel, because alcohol burns slower then petrol.

Some countries have petrol with alcohol added,NZ is thinking of doing it now too - 10% is the normal ratio.An easy natural octane booster.Trouble is it absords water - so any water lying around in service station tanks,or your own tank will also be absorbed,so the 10% is out the window.Steel tanks naturaly condence water out of the air,that's why the service station storage tanks never pick up off the bottom.At a certain point the water will drop out of suspension,then you got problems.I once did an experiment with petrol,meths and water to see what would mix with what in what ratios,dunno what it proved but it was interesting anyway.

Another thing I have found when adding alcohol to petrol tanks is it brings all the shit from the bottom with it,hopefully just blocking the filter.But once when I added an additive to the tank of my Nissan diesel which amoungst it's other claims was supposed to absorb the water.I think there was a lot of water and crap in my tank - it went straight through the fuel filter and into the injector pump,blocking the intake....expensive.I cut open the filter and unrolled the paper - not a trace of muck,so kinda pointless.

Water/methanol has to be injected separately to the fuel. But it does make a big difference to boosted engines.
