+1 if you want to use dino juice. I believe 5k is the factory recommendation? Later years went to 7,500 like in my V10. Severe is now 5k miles, which I run hauling 14k pounds. Stick with the Motorcraft filter and the body will rust out first.

The OP is in NY, there is absolutely no reason to run a 10w-30. Ford has recommended 5w-20 for 15 years now, it works.
