I have run 5w30 in my 97 F150 4.6 4x4 w/195400 miles on the clock, and for the last 25,000 miles I've had no engine troubles (knock on wood). I jsut switched to MC 5w30 about 1500 miles ago and noticed that the tick I had at startup is gone.

 

you make me laugh, too bad personal attacks are banned

 

The oil filler cap says 5w20 on my 02, so does the manual.

 

and MC 5W-20 is about the best bang for your buck.

 

Ditto to that.

 

Well if I made you laugh, then my work here is done. Wasn't that from almost a year ago anyway?

Lighten up, you clearly don't know sarcasm. Everyone has a different oil need based on all sorts of factors. I was giving my opinion....geez.

Good luck, bro.

 

Im thinking of going with a 0w30 m1 on the next oil change. My 97 has run on 5w30 from day 1 and now that 0w30 is avaiable, I dont see a down side. I also see that it meets fords 929 standard that others have noted in the board.
