Don't do this, unless you want to potentially tear up your injection pump and injectors. The USED oil has more contaminants and particulates in it than you realize, especially if the oil is coming from blown up wrecks. The work to remove the water/antifreeze and foreign particulate matter (bearing material and other metals) far outweighs any potential benefit. It sounds good on first pass, but its not worth the risk to your injection pump and injectors. If you wouldn't run used oil in the engine, why run it in the fuel system? I wouldn't run my own used oil in my 12V Cummins, let alone from someone else's blown up junk. Even 30 gallons of used oil is only 1 fill up, so $120 saved? Injection pump $2000, just saying......
