Yep, the savings on oil changes is pretty minimal, but by doing it myself I know exactly what is being done. I have heard stories where the oil in the car actually wasn't changed (e.g., my uncle, and father in-law). I have heard stories where the oil pan bolt has been stripped from over torquing it (e.g., my sister, a co-worker). I want to make sure that the oil and filter get changed, that they get changed with the oil and filter I want used, and that the oil pan bolt goes on smoothly. Those are the reasons that I do my own oil changes.

In the Ford diesel, I used Mobil 1 15w-50 when I changed the oil. The next time I change the oil I'm going to use Mobil 1 that is specifically formulated for the Turbo Diesel. I saw it at Wal-Mart over the weekend and I think it costs $25 for 4 quarts. Not cheap, but neither was my truck.
