I was wondering if there is some way reprocess used motor oil and other oils into diesel I know it wouldn't be cheap to set it up, but is it feasible to do it? if its a dumb question sorry. I can get hundreds of gallons of motor oil and transformer oil a month and was trying to figure out some way to cut down our fuel costs thanks

ther are a lot more question on this subject, do a search for wmo and read on, i mix waste oil with diesel

 

I was thinking more along the lines of turning it into real diesel like people do with veggie oil into bio so person wouldnt have to think about it just fill up. Is it even possible to re-refine into diesel or gas Im thinking out loud here. i have tried researching this but I cant find any information so any help would be appreciated.

 

i know that with the 70/30 mix you can tell there is used oil in the fuel, blue smoke and burn oil smell.
i would like to know also, maybe like thinging waste oil with solvent or something?

 

My understanding is that most of used motor is refined into diesel fuel. I just filter the used motor oil and pump it into my tank. Have run50/50 in my CTD, a little more smoke and burnt oil smell. Been doing it for a few years now.
