Im under the impression acetone aids in "exciting" or stirring the molecules contained in gasoline causing the vapor to hold together and not allow it to pass by the piston rings, or to hang out unburnt in the cylinder, With less surface tension allowing gasoline and everything else in it burn more completely.... Not saying I'm accurate, just my interpretation of the info I have come across.

 

So Especial, Can I call you Special? Special, what have your results been since you've started adding acetone to your fuel? What was your mpg before and after? I have seen a lot of retoric but no stats so far so if you could conduct your experiment and enlighten us as to the results it would be helpful to your point!

 

I'm waiting to get to a near empty tank, and then fill up 10 gallons of mobil 87 with the acetone going in first.... It's already in my ram but I'm at work with the f150 and driving 2 trucks is a pain in the ***... When I'm finished piping up this steam boiler il be using the ram to haul the old one to the dump, so it's gonna be a slow results watch if your waiting on me..... I didn't start this thread but I'm willing to try anything once.... I did put 3oz in the ram to 7 gallons of 87 yesterday and dropped the boiler and made parts runs with it. My odometer reading is at 213,410 miles at fill up. My point is for my own curiosity, I've heard this acetone argument and watched it fizzle before.....

 

Cool! Can't wait to see the results. I would just do it in the Ram though so you won't damage any thing valuable, lol. You could use the F150 as the control subject and try to drive them thboth in the same way.

 

I'm not a chemist, and I don't have any fancy degrees.

But I sure remember buying off the shelf octane boost over the years that contained up to 10% acetone.

I have no clue if it actually does any good, or bad....but I would think if used in very small amounts, that it wouldn't do any damage to most engines.

If you're stuck on using additives, perhaps a bottle of octane boost would be what your after....at least it has what the fuel additive industry considers to be a safe amount of acetone...and toluene...and xylene....and everything else that many say you should never put in your fuel tank.

If your gas mileage is not close to most other trucks with the same configuration under normal driving conditions, then I doubt any additive is going to help.

 

Last spring I ran acetone in about 10 fill up's. I would put about 5 oz in per fill up. In my truck I have a Scangauge II which tells me my accurate mpg's. It plugs into the OBDII port.
I actually saw a 1 mpg increase using acetone. The reason I stopped using it was because I was driving so much and filling up so much I would forget to put it in the tank. Then mentality would be "I'll put it in next time". Next time I would forget. etc....
Funny thing was today while looking for a tool in my trucks tool box I found the container of acetone under the tray of the tools box. (my tool box is a mess) and was thinking next fill up I would put some in the tank.
I also put Seafoam in the truck every 3k. I have yet to have any problems associated with the Seafoam or any problems from using the acetone.

 

This is what this thread needed a real world trial with results based on real world test.

 

I thought I was right in my raising octane comment.

 

A very good friend of mine (who is a mechanic) when they raced dirt mod's used to put acetone in the tank every race for that reason.

 

If you are going to use acetone in your tank, don't use part store stuff, as it contains a majority of water and/or other dilutants
Anhydrous acetone should be your choice, but is hard to get unless you deal with a chemical supplier, since it's a semi-controlled substance
