I've narrowed down my selection. I'm at the 4k mile mark on the factory oil. Will take it to 5k. I feel safe doing this with this particular engine. I've seen UOA of the factory oil at 5k with this same engine so I'm not concerned.
Mobil 1 10w-30 EP
Motorcraft 10w-30
Pennzoil Platinum 10w-30
Amsoil 10w-30
These 4cylinder engines run at high RPM's. I drive 80mph to work, 40 miles one way and it seems that 10w oils are usually less volatile and help with oil consumption. I was even thinking of Amsoil 5w-40 but that is too thick for this engine.
I like the add pack of the Motorcraft and PP. MC has increased the Boron a lot.
