Do these types of questions ever get old???? Use whatever is on sale. I've used MC 5000, Castrol, SuperTech syn., Mobil 1, and now I'm using Valvoline ML all 5/10w-30. I just purchased 36 qts of Napa dino oil so I will be using that for atleast 6 oci...
Oh, I've never seen Motorcraft 5w-30; only 5w-20. I'm afraid to use that weight on my car with my mileage. My baby doesn't burn any oil though.
