I actually added 1/2 a quart of oil and one of the engine treatment stuff that came in a two part solution. I didn’t check the oil before adding all of that but after it was at normal level. And one of the other reason’s I didn’t stop was that i was pretty much in the middle of nowhere when the oil light came on too. I pretty much realize now what I should have done, so that part really wasn’t very helpful. I would still like to know if this is something that is worth fixing on such an old vehicle and about how much it will cost to fix?
