Really , it's been done to death. This claim: "Complete vaporization of fuel
is far from perfect in today's cars and trucks. A certain amount of residual
fuel in most engines remains liquid in the hot chamber" is probably slightly
true, but that "certain amount" is not really statistically significant, and
the effect of a shotglass per tank of acetone on that marginal amount is
minimal. Gasoline is already seasonally formulated in many markets to more
closely tailor the vapor pressure of the fuel to the projected intake air
temperature, meddled with on a greater scale than the recommended 2oz
acetone per 10gal gas. What it comes down to is that all the "pro acetone"
stories are anecdotal, and every attempt to scientifically document the
stories in lab conditions have shown no improvement. You can improve your
gas mileage by inadvertently getting a plastic dinosaur wedged under the
accelerator. The difference seen by the anecdotal reports is easily
attributable to subconscious, "press the gas pedal a little less", wish
fulfillment.
