Well there is more additives in high milage that help remove deposits and sludge, but i reccomend mototr craft for fords, its a synthetic blend not full conventional and not full synthetic it seems to work best along with mototr craft filters, dont ever use fram. They are trash, unless (cant believe im about to say fram has a good filter) you use the highest level one they have which i think is like 9X the filtration but then still its not great.

I just changed my oil with Castrol high mileage and a fram tough guard. I've always used Frams myself and never had a problem either.
