Hello everyone I have read and heard about proved benefits of adding a very small amount of acetone to the gasoline for our cars in order to improve the engine performance and consequently the MPG. Seems like the optimum percentage of this mixing is between 0.1 and 0.3% of pure acetone. I would like to hear something under the chemistry point of view, before checking that in my own car. As many mechanics state: Can this acetone addition improve the fuel's ability to vaporize completely by reducing the surface tension that inhibits vaporization of some fuel droplets, in the way of maximizing the combustion energy? Thanks a lot in advance. .
