This I have to try! Apparently, adding acetone to your gas (1-3 ounces per 10 gallons [29-87milliliters per 40 liters]) can increase gas mileage by 15-35%. Just make sure that your gas station isn’t already adding acetone! Too much and your performance will decrease.
In other warnings, acetone eats paint and dissolves plastics. Should be stored outside.
In addition to increased mileage acetone added to fuel boasts other benefits such as increased power, engine life, and performance. Less unburned fuel going past the rings keeps the rings and engine oil in far better condition.
A tiny bit of acetone in diesel fuel can stop the black smoke when the rack is all the way at full throttle. You will notice that the exhaust soot will be greatly reduced and your truck or car runs smoother.
Acetone can reduce hydrocarbon emissions up to 60 percent. In some older cars, the HC readings with acetone in a 1986 GMC went from 440 PPM to 195, as just one example. Though mileage gains taper off with too much acetone, hydrocarbon emissions are nevertheless greatly reduced. Pure acetone is an extremely clean burning fuel that burns in air with a pretty blue, smokeless flame.
Acetone reduces the formation of water-ice crystals in below-zero weather which can damage the fuel filter. Change that fuel filter every year to protect injectors.
There are no known bad effects and every good reason to use acetone in your fuel. I have never seen a problem with acetone, and I have used ACETONE in gasoline and diesel fuel and in jet fuel (JP-4) for 50 years. I have rigorously tested fuels independently (with burns all over me) and am considered an authority on this important subject.
