This is what Mobil says about the new oil. [Mobil 1 Extended Performance motor oil is designed for today's longer service intervals. Mobil 1 Extended Performance products contain 50 percent more SuperSyn, 37 percent more cleaning agents, and 36 percent more anti-wear additives than Mobil 1. Mobil 1 Extended Performance with the Advanced SuperSyn System helps keep engines running like new and helps extend engine life by reducing wear and oil breakdown. Please follow the recommendations in your owner's manual while your car is under warranty. ]wildbird said:So is the gold 15W-50 the same as the red 15W-50 or is there a difference other than the cap color?
