Iwould change the oil filter with a Fram Ultra, much better filter than the Purolator Boss.
Can you tell me more about the difference F ultra / P Boss, ( Media microns?! )
The main difference is people have a hatred towards Purolator due to the semi recent tearing issues in their regular/classic filters.
As someone who’s been on here since the days of “Use Purolator not Framz!” People are gonna say what they’re gonna say, and there’s always a slight bias toward one brand of oil or filter.
AFAIK, the boss hasn’t had issues with tearing, and is more than likely just as good as a ultra in this case.
Find a ford spec 5w30, use it, with the hauling I’d find something with a good lump of Moly in it, which is more than likely going to be a SOPUS product
I’d use QSUD 5w30 or Pennzoil Platinum 5w30 and a decent filter
In this case, if I did use a Fram, a tough guard will be both cheaper and more than enough for the job at hand.
I swear the love for fram ultras on here is crazy, they’re good filters, but yeesh, people just say “filter” and people scream “FRAM ULTRAS!!” Y’all probably use them on your lawnmowers and weed trimmers too.
OP just find a filter rated for your severe service oci and call it a day.
Edit: now might even be a good time to try the new Rotella Gas Truck 5w30!
