Chevron Supreme 10W30 is a very good oil. However, I would not go more than 4000 miles with that oil. If you want to go the full 7500 miles use synthetic. The mechanics advice is screwy. Good synthetic oils include; Mobil 1 EP, Redline, Amsoil, Royal Purple. Some other so-called synthetic oils, Castrol, Penzoil, Valvoline, etc are not "true" synthetic oils. The differences between synthetic and dino include; how long you can go between oil changes, cold flow properties, overall engine cleanliness. The "pedal to the metal kind-of guy" has nothing to do with it.
