Acetone is a VERY POWERFUL organic solvent and will attack most elastomers used in modern fuel systems.

If you want to experiment, buy an elastomeric fuel system part and immerse it in acetone for a day and see what it looks like - if it's even recognizable - then dry and handle it to get a subjective feel for different properties versus before the part was exposed to acetone. Even in small concentrations acetone will shorten the life of fuel system elastomers.

Any claims for significantly better overall fuel consumption with a small dose of acetone are just pure BS!

None of these people appear to have even a rudimentary background in organic chemistry.

Don't add acetone to your fuel!!!
