The filter is only part of the story. Clearly, synthetic oil will lubricate way farther that dino oil. maybe 20,000 miles or so, but that's not the story either. The oil gets DIRTY! Changing the filter won't clean the oil already in the crankcase dirty. I't overkill and I know it, but I do mine every 3,000 miles on synthetic oil. The PT GT and THe Corvette. It's cheap insurance, I buy it by the case. An it's not Mobil 1 either, although that good oil. I use Chevron Delo synthetic 10W40. We don't have cold weather down here.
Cheers and Happy Holidays!
