What oil are you guys running
I know the ford manual says 10w30 but i tow a small enclosed trailer for work and was woundering what you guys run. In my 6.0 i ran 5w40 summer and 15w40 winter. Winters over now and time to change

5w40 Rotella. Why? Because. Motorcraft filters...all of them.

Motorcraft 10w 30 with a factory filter

You ran the thicker multivisc. in the winter? Would've expected the other way around.

Plan on using Rotella T6, 15w40.

The FSM calls for either 10-30 or 5-40 depending on conditions. Depending on what you call "small" for a trailer, it shouldnt fall into the severe category.
That said, I run 5-40 because 20% of my driving is short trips.

I run 5w40 year round. Vavoline PBE, Rotella T6 or Motorcraft 5w40.
