acetone as a fuel additive

[tigerbolt]

I also heard about acetone as a fuel additive. I tried it in a mechanical big cam 4 cummins diesel and it will run better and clean up the smoke a bit. Mileage did improve slightly "BUT" combined with the ULS fuel nowadays it ruined my fuel pump and 2 fuel injectors in 8 months time. Seems it reduces the lubricity of the fuel.
I also tried running waste veggie oil in this same engine. I got it from a pizza shop (10 gal.) I heated it and ran it through a 100 micron, then a 10 micron, then a 1 micron sock filter. Cleaned up pretty good but still had a brownish color to it. I added the 10 gal. filtered oil (cold) to 90 gal. of diesel fuel and it plugged up my fuel filter before I got out of the driveway. Somehow it must be preheated or remove the glycerin.

Acetone is a powerful solvent, so it should not be used willy-nilly in systems that were made where someone did not consider it might be used.

Bio-diesel is made by knocking the glycerin out of vegetable oil. Otherwise, you have to heat the oil and also do a purge before you shut the engine off or you will have troubles. I would also think you would want to run the oil through a separate filter and tie in downstream of the regular fuel filter, but I'm not sure on that.

This looks like a don't-do-things-you-shouldn't thread, so I agree.
