I use Mobil 1 10W30 Synthetic in my S2K with the Mobil 1 synthetic oil filter. How often should I change my oil with normal S2k driving? I do not race or drive like F1 driver. Just a short daily commute to work 20 miles total and longer weekend trips. I was thinking 3750 miles. I sense that is overkill. 7500miles? At 30 dollars a case for synthetic, its not cheap. Is Mobil 1 the best bet?
