Marshall totally opposed the use of used motor oil. He said "why would you take something that has too much soot in it to run through your engine, then run it through the IP, which has much greater tolerances/far more sensitive."
FYI, I have done this, using oil filtered through a 1 micron absolute filter bag. The oil is still black and after letting it sit for several months in a fuel container, I used it up and there was a thick coating of sludge at the bottom - all less than 1 micron sediment. I quit using used motor oil after that. Marshall also said that the ash content of the oil will cause problems. He said that if you had to do it, use the straight 30 wt stuff for older cars, which is now, BTW, $1.39/qt at wal-mart - used to be $0.93/qt a couple years ago.

I seem to that remember pouring a quart of motor oil into the fuel tank occasionally was good for the car." I think I remember that Marshall Booth used to say that a quart every once in a while won't hurt anything, but he also said that mobil 1 will not completely burn and if you do this frequently it could lead to coking up the injectors. He didn't say don't do it, but I don't think he recommended it either. I wonder what burning all that soot would do. It doesn't seem like enough of a benefit to outweigh the potential risk. Donald H.
