nothing is better than a quality synthetic diesel rated motor oil.

The only part I have not done is switch over to synthetic oil, only because the oil in my 85 was new when I got it. The first oil change I do I'll be changing. Rotella is in it right now. New tires, filters etc have made noticeable differences. Getting the things like the the rockers adjusted correctly, turning up the boost etc made a huge difference. On my 81 NA, I have have a 83 rear end sitting here waiting to go in for the taller gear.
