So I recently talked with a guy who says hes making what I guess would be called biodiesel out of used motor oil....anyone heard of this?
Nope, he just called it biodiesel. I guess its still considered waste or a by product...not really sure though. I have been looking and havent found one thing about it. I watched him pump it into his truck and drive away. It looks just like motor oil, he said its easier to make because you dont have the fats in the oil. He also said it costs a little less than a dollar a gallon, which is about 50 cents less that what I make my biodiesel for.is there any special name he called it?
He told me that his reactor takes about 5 days to make 100 gallons, not bad to me.I read a post one time on another forum that it was possible but it takes a lot of time & heat and other stuff to convert the used oil in to usable fuel. IIRC the process to do it is along the same line of how they have to crack crude oil in to unusable products.
No kidding huh? do you make it like you would make biodiesel? What other addatives are you adding to break it down? I hear Cetane and something else are a must.I know of several people that are doing this now. My freind that is doing this told me that if you use used motor oil, it is broken down and diluted a little from the fuel getting past the rings enough that you can just mix it in with regular deisel fuel. He started with a 30 percent mix. In the summer months he runs 70 percent. His truck does not some too bad bud it does smell like buring oil. he has a filter set up he uses to filter the used oil. I have started doing the same, when i change the oil in my truck or cars i just pour the waste in my tank. I have not been able to tell a difference at all. I have a new truck with the particalate filter. you are not suposed to do it with those but it has made no difference.
