I have been reading some of the other threads about when to change the oil for thr first time in new cars or trucks. I have about 1000 miles on my new truck and I'm itching to change it. I have read in the owners manual and it says nothing about leaving the oil in until a ceratin mileage. I plan on adding the maintance dose of Auto-Rx along with MC 5W-20 and MC filters.
Thanks
