However, if you didn't want to pay the price for a full synthetic, I would recomend motorcraft oil as it's a synthetic blend and cost about the same as other dino oils in it's class. With mobil 1, I get 5,000 mile oil changes easy, it could go longer, but it will need a new motorcraft filter by then anyway. There's mobil 1's that can go up to 15,000 miles between changes, but there's no 15,000 mile oil filters that I know of ha ha.
