I have an '08 Chevy Silverado with the 5.3. Just curious if any other Chevy owners have an opinion on what brands of oil this particular engine likes? I heard that GM's oil is made by Mobil and is basically Mobil Clean. I usually run 4-6k OCI's. I have ran both conventional and synthetic oils. Dino's I've used: MC5000, Pennzoil conventional, Valvoline. Syn's: Mobil 1, Pennzoil Platinum, Castrol Syntech, Mobil 1 Truck and SUV.
My OLM decreases about 10% for every 1000 miles I drive, and if I were to follow the OLM, that would mean a 10k OCI! The OLM has indicated this regardless of conventional or synthetic.
