You can also blend in your used oil drained from the crankcase… we did it all the time with our 18 wheelers in fleet operations..
Every time I had a load of fuel delivered, I’d have the shop dump the waste oil tank into the fuel delivery…
I knew a guy that would mix filtered waste ATF waste engine oil, kerosene and even used gear oil into the tank of his '92 Dodge with the Cummins mill. He called it "Old Smokie".
