For the winter try 0w30. I have been running 0w30 over the winter and it works very well. The truck will start easier that with 5w20. Really I could run 0w30 all year round but when it gets warmer I just put in 5w30.

 

I wouldn't go to 5w30 or a non FORD oil filter and here is why. Your timing chain tensioners need oil to work properly. During cold start ups or the engine sitting for long periods of time the engine does not get oil to this area of the engine at startup initially and running a thicker oil to slow down that process isn't a good idea. Ford found running 5w30 in the early models of the 4.6 and 5.4l engines were prone to tensioner failures and guides cracking due to the tensioners failing. Ford then changed their stance to switch to 5w20. For my engine I would only use 5w20 and a anti drain back filter.

There is a good article on the internet somewhere.... Ah yes, here you go.

It's your engine, do as you will!

Here is a failure, notice he is running a NAPA filter @ 4:41... No idea what engine oil he was using.

 

Ford had earlier runs of junk tensioners that is what it boiled down to. The modulars were not the only ones either. When it is warm outside the difference between a 5w20 or 5w30 at startup is not big enough to cause issues with oil starvation due to being too "thick". In cold temps like say 0 degrees both oils act like a 5w oil. Oil starvation at startup is likely to show in the the upper end (cam journals, rocker pivots and etc) as that area is the last to get oil. It seems like the guy in that article came to some sort of magical conclusion with no TSBs or other solid proof to back it up. If we go by that my tensioners should have blown up years and years ago.

The 3V modulars with VVT like in the video had their own issues, a lot of which was bad cam phasers. A LOT of bad cam phasers, especially the earlier models. I always figured the primary reason Ford switched to 5w20 was for CAFE reasons along with trying to reduce stocked oil weight.

 

Been running 5w-30 Mobil 1 Extended Performance for a while now. Haven't seen much difference on MPG but it seems like some of the modular noises quieted down. Seems like oil consumption has dropped a bit too.

 

Both of my 2000 V10s had 5W-30 on the oil fill cap, later it was changed to 5W-20 but I stayed with 5W-30 on both. My work truck that I sold with 99600 miles when I sold it with no problems, I sold it to another contractor and last I heard it had 287k on it and they were still running 5W-30 Mobile 1 just like I ran. My other V10 I ran 5W-30 Mobile 1 for 130K with no problems right up to the time I traded it.

My work truck used one quart every 2K miles from new and twice it got worse, one was form a pcv problem the second was when I had it changed at a dealership where I was upgrading their A/C system and they used 5W-20.

On my present 6.2 if I can get a answer on warranty problems if I charge to 5W-30 I will change because of the way I use it with 80% of the miles pulling. My F150 with 4.6 I will stay with 5W-20 because it only pulls its own weight 95% of the time.

We just found out the other night when changing oil on our 2016 v10 that Ford switched to 5w30. We are use to the 5w20 in our 2012 v10 and thought maybe they had the wrong oil cap.
