I'm waiting to have my truck inspected. This will be the third time that I am having it inspected. An inspection is good for two years. It has yet to pass right off the bat. I have always had to do some sort of repairs and have it re-inspected. Usually I take it in with fresh oil, plugs, wires etc. This time I'm just driving it in like I don't care. I'm going with the Adam approach. When the crank shaft hops into the passenger seat, I'll think about changing the oil.
