Was just changing the oil in my truck (1994 7.3 IDI NA) and was wondering if there is any harm in just putting the waste oil into the fuel tank. We're talking like 12 quarts plus. I would make sure the tank is full of diesel, about 18 gallons so it would dilute sufficiently. I have a 500 mesh screen ( about 25 micron) I can pour it thru to pick up any small chunks of stuff that may be in there. Just thought it would be a convenient way of disposing the oil rather than hauling down to the parts store to dispose of it. Do you see any hazard in doing this? I am just doing this as a means of getting rid of my drained oil, so it would only be done when oil change time comes around. I know some of you are using waste oil to power your trucks, so it seems doable as a means of getting rid of the waste oil. Is this a good or bad idea?
