Just an FYI to newer owners of 6.7 Powerstroke. Not sure if anyone saw/heard this at all, but last month Ford came out and said not to use some brands of CK oils as it wasn't "meeting" certain Ford tests (namely wear if not mistaken). Upon reading this, I said to myself "WTheck?" Called to a maker of oil I use and have been using and it seems that the 1 type I want to use is 1 that "doesn't" meet Ford's criteria for now anyways. He suggested using a different type (blend VS full synthetic) as long as it's in warranty. The blend oil is CJ oil and full synth is CK. However, spoke to Ford dealer and he said it's just a bulletin and Ford cannot change the warranty in mid stream if your engine calls for CJ oil and all you can get is CK. Course he is saying Ford is recommending to use their oil., read $$$$$$$$$$If others could chime in with opinions/ facts or other would be great.

If its true that the new Powerstroke is good for 300k miles, I guess if it doesn't like my oil and wears out in 200,000 its not going to make any difference to me.

The government got involved with motor oil now and anti-wear additives like ZDDP, that have been used for many years, can no longer be used. It would be best to use an oil that passed Ford's tests. Of course this forum will not let me post a link because of the percent issue.

I just use the Motocraft synthetic. Its just as cheap as any of the name brand synthetic oils and they won't say anything against that brand.

I use Shell T-6 5w40 Full Synth in a 2014 6.7....What do they saw about that oil ?

So... Ford is blaming oil for the reason their engines fail.

Did you happen to notice that the Ford oil didn't make the Ford approved list?

You need to understand that things have changed. With the beneficial anti-wear additives removed, the Rotella has not passed the Ford testing. Rotella no longer tried and true. Suggesting the use of a product that you know is faulty is not something I would do. Yes, I have used T6 and when my supply runs out it is time to find something that passed the tests.

The anti-wear additives are no longer used to make the greenies happy. Ford tested oils to check for wear, and now many no longer pass those tests. There is no mention of high mileage or commercial use, wear is wear. It's your truck, so if increased wear is what you want, use whatever you want.

Yet Shell states that their new ck4 oil provides better wear protection than did their previous CJ4 oi.

For those that haven't been very frustrated by odd symbols not being allowed in computer applications, you have to spell out the word percent on this forum. It will not accept the upper case 5 but won't tell you why or what is giving you the error message.

The Rotella T6 is not on the list. Please show where a Shell full synthetic motor oil meets the Ford WSS-M2C171-F1 specification. Yes, some blended and conventional Rotella are approved.

List

That's an awesome post/list!! This covers/answers which oils to a "T"! Thanks for sharing the link.

Noticed that Amsoil and even Motorcraft were not on it. I feel that Rotella T6 will be approved in short order (few months). If not, will use Valvoline full synthetic for wither use.

Shell Rotella: T4 10W30 and T5 15W40 has Ford's latest oil specification.

Also Valvoline Premium Blue Extreme 5W40 has Ford's latest specification too.

It's pretty simple to determine what will pass Fords specification. If it's a API CK/SM rating you should be good. If it's a API CK/SN I would use with caution for now.

Roger that.......

Well use of the correct oil, and reasonable change intervals (10,000 miles, the insides of your engine could look like this at 298,500 miles.:B
The Tappet cover on our 2001 Ram, finally started leaking, so took a bit of time to replace it. Got a very nice surprise when I removed it.
I use Chevron Delo 15-40 LE Dino oil.
