The Motorcraft oil filters are very good filters at a very good price, I use them. As for oil, in the warrenty period I would use the oil weight recommend by Ford. You can use a good name brand oil that meets Fords specs if you want, you do not have to use Motorcraft oil.
All manufactures use the same base oil with some chem pack modifications between oils for diesel and gasoline engines. If any..
This way, or the other I strongly recommend do your own test. There are millions myths about oil change for each opinion based on actual testing.
With the cost of oil changes on our engines, the $25 for lab test seems to be a bargain. You will get your money back if they allow you extend the interval by only 2000 miles.
