:pray: Ok so the other night I was talking to a friend and he told me that he runs a mixture of 50% oil and 50% diesel fuel in his pickup, is this possible? He says that he runs anything that he can find (hydrolic, motor, tranny oil) after he puts it through some filters and just dumps it in the tank? Won’t the oil mess up something? If it is possible then what would be a safe mixture? I work for a petroleum division and could get the stuff for free if that is the case:thumbsup

My cousin does the same. It is not safe, I wouldn't use it on a new truck. He uses it in an old 7.3 before the powerchoke. It is very possible.

You can probably get away with a 75% diesel and 25% used oil if you filter it enough. The big probably is that the fuel is a lot thicker than regular diesel, and it puts a strain on the lift pump and injections pump.

Search the forum because there was a good discussion about this a month or two ago. Yes it is possible, it will decrease mileage however it was free anyways. I havent tried it and would be kinda worried to try it but it has been proven. Most people who do run 50/50 mix or less. Does also decrease power and increase smoke

Personally I would not burn waste engine oil or any other petroleum based lub since there are heavy metals in the oil and it will burn VERY dirty. I mean am no tree hugger but burning waste oil is a little too dirty for me. I would imagine a common rail would not be a big fan of it either.
