'Robin Rumbolt's Report of Directory:Acetone as a Fuel Additive Effect on Mileage and Performance in his 2-Stroke Paraglider'

Reports

Paraglider 2-stroke saw increased mileage, decreased oil leakage, lower build-up on spark plugs, increased power, no impact on gaskets.

Individual Reports

May 31, 2005

I am a powered paraglider pilot. I fly with an 80cc 2 cycle engine

which requires an oil/gas mixture. After trying acetone in my Toyota

Tacoma truck and seeing a 12% increase in mileage, I decided to try

acetone in my flying machine as well.

Before putting acetone in a system that has Tygon hoses and rubber in

the diaphram, I soaked several of the parts in pure acetone. They

swelled just slightly. I also put acetone in a small vial of fuel

mix and let it sit undisturbed for several weeks. I saw no

separation of the fuel/oil mix. Then I tried it in the engine

itself. I used a mixture of 9cc acetone per gallon of fuel mix.

This corresponds to 3oz/10 gal.

The first thing I noticed was an immediate increase in idle rpm by

1000rpm! I had to reset the idle screw.

I also noticed that the mixture screw had to be reset for max rpm.

I had to close it a bit.

I have now had a half dozen flights with acetone in the fuel.

Further, the fuel has been allowed to sit in the plastic tank for 3

weeks with no apparent degradation.

My paramotor typically uses about 1 gal of fuel per hour of flight.

Last night I flew for 0.9 hr and used only 1/2 gal of fuel! I have

also noticed a 1000rpm increase in max rpm while flying. This means

more power!

Usually after a flight, I have to wipe the oil off the prop. (The

unburned exhaust goes thru the prop.) I have seen a dramatic

decrease in oil on the prop, indicating better burning of the fuel.

The spark plug is showing a good brown coloring, and I have seen no

carbon buildup on the piston. Carbon buildup is typical of these

engines.

In short, I have found acetone to be beneficial in small 2 stroke

engines too!
