Fuel Revisited

I ran across an article about using a couple % of acetone in fuel. Anyone actually done this? After my LHS switched from 15% Nitro, castor/synthetic blend to 15% Nitro, 18% straight synthetic, I have had to re-adjust everything I have used it in. It may be a coincidence, but planes that I have flown for years and are rock solid performers now need to be re-adjusted for the fuel change. It doesn't make sense that going from castor to straight synthetic oil would make such a difference, so far, every plane with the new fuel needs to have the low end tweaked so it won't die in flight. Thanks Bill

the technical information . I recommend 3% acetone. FWIW Mobil racing no 5 fuel is actually 97% Methanol, 2% acetome and 1% castor.

What does the acetone do?

Bill,

I am curious to know if acetone would remain in a state that could disolve or soften plastic. Adding acetone may compromise components of your fuel system. I would suggest testing by adding say... 30% acetone to off the shelf fuel and store in an old tank- (1/2 full)- and tubing of the desired materials and wait a month to see if the tank geometry or structural integrety has been compromised.

P.S.

I would avoid technical grade acetone because it is extremely hydroscopic. Pure acetone may be difficult to acquire.

Please post the results if you do wish to test.

Thanks,

castor/synthetic

I use a couple of caps of unleaded gas to a gallon of straight synthetic fuel. Done it for over 10 years, motors run sweet, and no degredation of fuel tank or pipes. My favourite model is 7 years old and still going strong.
