Mythbusters shot this one down, along with magnets and a few other magic mpg improver's.

Waste of time and money.

 

Do you really think the oil companys want you to know acetone will increase your milage! Straight acetone will eat up pretty much anything but at point 2 of 1% has no bad effect on rubber parts Triton

 

keep thinking that brother. It sure isn't something I would do.

 

Triton that was my first thoughts also

 

I've ran Acetone and it ate through some of the rubber tubing on one of my crappy cars! DO NOT USE!

 

Well, I'm not one to always follow the book myself but, I know better than to use acetone. Acetone no matter what the dilution is a stripping agent. It will break down oil, grease, rubber...etc. Maybe if I were cleaning my injectors to sterilizes them of oils and lubricants I'd use that.

This was just published at the end of Oct. It's not from Cummins to hide things like " acetone will give you better fuel mileage " but, to add mechanics or anyone involved in using the correct product for the motor. I didn't read all of it but, I see no mention of acetone. Fuel for Cummins

I say though... if it works for you, go for it !

 

Take a sample of gasoline
give it to a skilled lab tech at a Lab like Oak Ridge
slap it in a mass spec for analysis
and odds are it will show the in spectra
that there is already so many part per million acetone
in the gasoline in the first place.

Gasoline is a mixture all all kinds of hydrocarbons
that 'fractionate' out at a certain temperature in the columns of the refinery
but the distilling is not 100% efficient
and there is a little bit of everything in common everyday gasoline.
It is not a 'pure' product in any way.

This is the reason engine test labs used to always test with 100% chemical Octane...which is a pure product....always the same.
Unfortunately this is not as common practice as it once was.
