Do you have the Boron numbers of Mobil 1 ect?I'm intrigued about the Boron comment also. I dug up Blackstone reports from other vehicles, and Ford Full Synthetic 5w30 appears to have around 134 units of Boron. Motorcraft Synthetic Blend is at about 107 units. Regular Amsoil 5w30 shows 150 units. Blackstone's universal average Boron content is about 50 units.
Since the regular Amsoil OE stuff is about on par with other full synthetics as far as cost goes (and meets the Ford oil spec), I'm most likely going to be running this oil.
