acetone as an additive = better MPG???
 

Any truth to this



One ounce of acetone added to ten gallons of diesel fuel will reduce soot and improve fuel mileage an average of 22-percent. You will also notice a slight gain in performance.

We used to use acetone as a poor mans race fuel, too much and youll be picking up parts of your pistons in a gas motor. you couldnt pay me enough to run a corrosive item like that though my injectors, injector pump and then try and burn it. Just my thoughts Good luck if it works keep us posted, but i wont try it.

Seen a lot of things come and go, most of them silly and obvious... but never heard of this one. I'm no chemistry rocket scientist or anything by any means, but this sounds hokey to me, just doesn't seem logical that such a small of anything could make that significant a change in mileage/performance, portions of it may hold true (maybe the emissions?).

I think these numbers are accurate (if not someone more qualified has permission to jump on my head and tell me otherwise) but it's my beliefs that giving a properly tuned diesel engine burns nearly 70-75% of the fuel for each combustion and a gasser is somewhere near 60%....the only way to get the gains mentioned would mean you would have to increase the overall efficiency burning that remaining fuel while still in a productive portion of the power stroke. For scavenging engines that use some the still burning fuel running out the exhuast there would little left for them to actually produce power from. Still looking at a purely physical perspective the amount of fuel injected into the engine isn't going to change, so to see that much a gain seems very improbable.

Smells like snake oil to me. With some more research I would consider trying it in a lawn mower engine I wasn't very fond of, but not so willing to try it in my truck

well I dono nothin and most of the time I can proove it...it all comes dwn to btu (s) and a push on the piston. What is being said is not enough ratio to change anything or even hurt yout ctd.
In the cold in WY. we use to 20% gas to diesels to stop them from gelling................never saw improvment in milage......

I know Naptha can be used in a gas motor as an octane booster but never have I heard of using Acetone in a diesel to improve mileage, the only way I could see this argued is if the injectors have crud built up in them and the acetone cleans this off so the injectors could work better. I'm not sold on the idea.

By using 20% gas (sounds a bit much IMO, I heard 10%) you'd be lowering the net energy per gallon as diesel has more energy per gallon than that of gasoline so the mileage would go down if anywhere.

At a mix ratio of 1,280:1 I suspect the acetone acts as a combustion improver, providing better atomization of the fuel, after reading through those articles. At that concentration, the solvency effects should be beneficial, rather than harmful. Note they only recommend it's use on every other tankful. Acetone's rated octance is 150.

Schaeffer's Speciality Lubricants produces a fuel treatment product called Neutra that acts in the same way, and is safe to use in both gasoline and diesel engines.
