Fred , What grade of thicker oil should I try ?I use 5W-30 mineral oil in both the M , the 99 Pathfinder , and my 91 Q . The Q , with 147Kmi. still burns only half as much oil as the M . I normally change every 3500-4000 mi. My service manager have always recommended I should stay with the 5W-30 grade in theV-8's . Something to do with sloshing / aeration of oil in the crankcase, which is shallow design on these engines.
