I just bought a 1997 F-150 with the 4.6L V8. Is this one of the engines that's back-spec'ed for 5w-20? With 200k miles on the clock, I think I'll probably stick with 5w-30.
I think it has sat for a little while, so I changed the oil today after driving it about 400 miles in the last two days. I put in Peak 10w-30 and an STP filter, neither of which I'm excited about, but I figure a short OCI like maybe 1000 to 1500 miles might be a good idea, followed by a good 5w-30 with a filter I like better, say a Motorcraft FL-820S.
What do you think?
