I run Rotella 5w-40 in mine and change it at 6-7k and comes out a lot cleaner from lbz (egr blocked and pcv roroute) than my lmm at 3k. Im sure I could go further but I drive a lot of short distances in dusty conditions and pull hard and heavy fairly often.

Thanks. My wife is picking me up some dino oil tonight. changing tomorrow and getting a sample at the same time. Drive a for a week then change again. should have all the dirt out by then.
