WHat kinda oil have you been using?all of them seem to be set to come on at or before 3k. Mine did, then again at 7k and again at 11k. I dont use my truck in the most severe conditions so i dont think that thing knows. I just reset it and change my oil at normal intervals.
If you do a lot of towing if you use Amsoil you could go 12,000-15,000 miles between changes.Thanks for all the info. I use my truck to haul cattle, and was wandering if I could go 7500 miles or longer instead of 5000 miles with normal oil?
