Engine Oil
Hi all,
New 2015 Powerstroke owner here and trying to get ready to do my first service.
It seems Ford has come up with new criteria (WSS-M2C171-F1) that oils must meet for these engines.
I used to use T6 in my Cummins but it now has a CK4 in the starburst which Ford doesn't like.
Does anyone know if T6 meets the Ford requirements?
Cheers

Hi again, Shell Tech Support supplied me with Tech Data Sheets for T6, T5 and T4. They all make the cut for those interested in using these products. I attached the T6 version. as that's my oil of choice for the past bunch of years.
Cheers

For a while T6 wasn’t on the list. What got it back on, formulation change or requirement change?

Like most of the oils, Ford had to run tests or review tests from the oil companies on their oils to see if it met the wear requirements of the valve train.

Around August 2016, T6 5w40 significantly dropped its ZDDP antiwear additives below 1000 ppm when CK4 came out. Ford would not approve this weaker oil. So T6 5w40 in the middle of 2017 increased its P and Zn (ZDDP) back up to above 1000 ppm, and Ford then put it on the F1 approved list. So, yes a formulation change. There's more to the story, but this is the short version.

Thanks for the oil links. Had my first and last oil change done by my local dealer. Next day oil dripping down the filer. To say the least I'm disappointed. Dealer says bring it back and they'll resolve the problem.
Haven't changed my own oil in 15-20 years, that will change. I won't need to spend 160.00 for someone to do a **** poor job again.
Sorry for the rant.

I have some Motorcraft 10w30 left so for my upcoming next change, I'm going with it. I only daily drive my ride for now, but when I have a plow and camper, T6 5w40 is on my list. Check out Amazon for good prices and free shipping with Prime. I've always been a fan of synthetic oil. Time to start running it. ✌

If it only says CJ-4 then I think you're OK. Ford had a problem with the early formulation of CK-4. For a while, guys were snapping up all the CJ-4 they could find.

Does the T6 have the CK-4 designation on it? If so, is it their newer recipe of T6 or the older version that Ford didn't like? I don't know if you have a problem or not or how you would even tell. If it does have the new Ford approval on the label then I would say you're good to go.
