Why does the list specifically say CK-4 on some oils and not on the other oils listed. Rotella said they are working to get approval from Ford and sure enough their CK-4 oils aren't listed. If the list doesn't say CK-4 next to the oil, then I'm safely assuming the oil listed is CJ-4.

That was a good catch Roadrunner. I agree with that. Better safe than sorry.

Rotella CK4 oils that are Ford approved:


T4 10W30
T5 15W40

I'm sorry if I'm missing something, but where does it say those are CK-4 approved oils? The list isn't titled "Approved CK-4 oils"

With a video from Ford saying don't use CK-4 oils, why would I assume those listed above are approved CK-4 oils. Like I said, some do specifically say CK-4 approved, but those above do not.

WSS-M2C171-F1
This is ford's specification number for CK4 oils.

So the brands and weighs listed is approved CK4 formulas.

While I'm glad that Ford may be stating that this new certification is not good for our engines, I think they should do a better job of informing people. I think this forum is fantastic and I have learned a TON on here, but what about the people that buy these trucks and aren't on here? They have no idea and just go pick up whatever is on the shelf without knowing any of the information on this thread.

Ford should have sent out a letter to everyone that bought one of these trucks about this. Just my $0.02.

I agree. I wonder how many quickie lube shops are putting in the wrong stuff.

This is the difference between being a consumer and an informed consumer and I'm afraid the consumers are going to pay a heavy cost for real-world testing of CK-4 oils in engines that were designed for CJ-4. This is one of those things that I really hate about the gubmint. They mandate obsolescence of a critical mechanical component so the total system will fail sooner and all consumers will have to spend money to purchase a narrowly better system. It just seems wrong to completely remove CJ-4 oils from a market that is dependent upon them and state so cavalierly that the CK-4 will work even better. Ford's own testing showed this to be completely untrue when their test engines started wearing out sooner than they should have. What a bunch of horse crap. Eventually Ford will have to be a team player with the bureaucrats probably under threat or else.

The CK-4 designation has nothing to do with the government, local, city, state or federal.

This has to do with an industry trade group trying to make their products better.

And no one is mandating anything. Manufacturers can still make CH-4 if they want to, but no one will buy it. When was the last time you owned a car recommending 10w-40 oil? For me, probably a decade or more. But they still sell it, because someone is still buying it.

So if there was a market for CH-4, they would still be selling it. If they are not selling it, it is because no one is buying it. Supply and demand, not the government.

It's only CK4 but they put both because CK4 is "supposed" to be backwards compatible. It is not according to Ford.

I am not here to convince of what you have already decided otherwise.

If you want to believe that Mobil1 does not meet Ford specs because of some government conspiracy, then please go ahead.

From the API website explaining the benefits of CK-4 oils over CJ-4:

[CK-4] oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API CK-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase.

Um, you forgot to copy and past the part that said...

"CK4 is a new API diesel engine oil-service category, designed to help meet federal greenhouse gas/fuel economy standards, which have a final phase-in date set for model year 2018 trucks..."
