Interesting... For 2016 Ford recommends 5w30 for all gas engines in the superduty. The 6.2L V8 and 6.8L V10. Up until this year they have been recommending 5w-20 for both engines... So why the change after multiple years of both engines on 5w-20?
Ford changes oil grade recommendations for 2016

I'm loaded up for my 2015 SD with 5w20 but started buying 5w30
on sale. I guess I'll go over to the 30 side........

Maybe the engineers that designed the engine now feel 5W30 is better suited.
We can't blame CAFE for that change. Warranty claims?
Is it in the chassis cabs or all F250/350 applications?

Have there been any oil related TSBs or Recalls?
That's in the regular pickup truck owners manual for 2016. F250-550 (as the V10 is only available as a chassis cab).
I haven't heard of any oil related issues with either engine. They are both regarded as being very easy on oil.

I won't say this as intelligently as it should be said, but:
This kind of goes along with the 5w20 vs 5w50 in the Mustang's 5.0. Perhaps the cushioning layer and heat resistance of 5w20 was found to be a little thin for the HD applications. This is suggested by posts from some lubrication experts on here about the chemistry/hydrodynamics/etc differences between the different thicknesses.
Ford's engineers probably did some testing and noticed increased wear in some places that was reduced or eliminated with the 30 weight. Kind of makes you wonder if they'll test 40 weights....

30w oils seem to be more the de facto standard nowadays. Some are going up to 30w from 20w and others are dropping from 40w to 30w. Makes it very nice. I can use pretty much the same grade oil across the spectrum.
Up till now, CAFE stuff did not apply to class 2 or higher trucks. That is all changing. Even the Class 8 semi trucks are coming under scrutiny by the gooberment for mpg improvements. They are changing the oil classifications for those applications as a result.

The 5w30's seem to be getting slightly thicker since SN became the spec.
It seems viscosity went from the low 10's to the upper 10's and low 11's @ 100*C since the latest spec. came about.

You mean I
Have been wrong
All along using a 5w30 grade in my Focus and old 03' Taurus I had?! Shucks!!

I was thinking the same thing. It makes you wonder, time will tell.

Sooooo is this a Ford problem or are we going to see other manufacturers start doing this? Im thinking this is isolated to Ford. Ford has changed oil viscosity recommendations on its engines more than any manufacturer i can think of. Not knocking on Ford or anytbing.
Heres a thought, maybe ford uses 5w-20 for cafe purposes and then later releases a service bulletin stating that 5w30 is recommended and they dont have to retest their engines with 5w30 to comply with cafe standards?
Needless to say, i wonder if Ford will state why they recommend these new changes. Kinda scary, because it will start a war between 5w-20 vs 5w30 again...

That's extremely interesting. I've had three 6.2L Super Dutys. One is a 2011 with 160,000 miles. Always had Motorcraft synthetic blend 5W-20 & it still runs excellent. The 2012 has always had 5W-20 as well. No oil related issues, or any issues at all. I honestly hope they back spec our trucks to 5w30, I'll gladly use it. A thicker oil during heavy towing is never a bad thing.
