Best recommendation is to use the motorcraft filters and CJ-4 oil. If you do it yourself you need to let the truck sit for 10-15 mins to ensure all the oil is in the pan.
Put in 14 qts, run motor let sit and recheck after a few and see if full.
Being new I changed mine at 3500 miles. IMHO going over 5K is just too long so that is when I do mine.
As far as additives, some here are using them. I am not and I am getting along just fine.
