I’d recommend using motorcraft FL820S filters only. They have better anti drainback valves than the Fram filters and will help retain oil in your top end.
I use Motocraft oil filter also available there.
My opinion… 5W-30. I drive mine year round in a cold northern state. I was always told that if you’re hard on it at all and run it into higher rpm’s sometimes the coyote likes the heavier weight.
Recently changed oil and filter, installed Motorcraft filter.
I use Motorcraft Full Synthetic (or Castrol Edge Full Synthetic). The oil filter is Motorcraft OEM. Everything gets changed every 5,000 miles.
Motorcraft filters use a silicone anti drain back valve ADBV. Cheapos use rubber ones that get hard in the cold and don\u2019t seal. If they don\u2019t seal oil leaks out of the hydraulic chain tensioners and they aren\u2019t pressurized when the engine starts, so the chain isn\u2019t tensioned and it rattles for a second against the plastic guide before oil pressure comes back.
I use Mobile 1, 5/30 in my F150 EcoBoost...287K on it. Change every 6K . And I am an absolute believer in OEM filters. My new Bronco gets the same treatment. Don't skimp on the filter.
Motorcraft until they tripled the price. Got a bunch of Purolator Boss’s before their price went up
I'm not sure if the 2008 v6s still had plastic tensioners, but I know my 2004 4.0 did. I had to have it replaced at one point. Unfortunately with the 4.0 engine, removing timing covers with the engine still in the truck is kind of difficult and a shop might want to pull it to do this kind of work. I believe that's what they did on mine. Using motorcraft oil filters could help, but it didn't make mine go away, so I eventually had it replaced.
Stay away from Motorcraft filters, they are aweful.
