Ford put out a notice that the new CK-4 formula oil will not protect Ford engines.
I have heard that is not good for the 2016 and 17 only.
I have a 2003 6.0 with 320k and have used Delo 400 LE cj-4, can I use the new ck-4 in my diesel?
Thanks

 

There are going to be a lot of 5W-40 and 15W-40 bottles with CJ-4 and CK-4 printed on them, that will also show up on the WSS-M2C171-F1 list. Rotella T6 is currently sporting both CJ-4 and CK-4 ratings, Rotella T5 has both plus is on the WSS-M2C171-F1 list. Use whatever you've been using, the changes to the additive pack aren't going to make a difference in the old trucks.

That whitepaper is a pure CYA from Ford IMO. The list of "approved oils" is about a mile long:

The 5W40 section is laughably short, you'll notice not even Motorcraft 5W40 is on that list Think there's really gonna be anyone who believes Ford's own private label diesel oil isn't up to Ford's new made-up specification?

 

Thanks Texastech for the info.
Will stay with the Delo 15w-40

 

Rotella = garbage

Stay with delo for sure

 

Motorcraft 5w-40 is still CJ-4, so it would not appear on a list of approved CK-4 oils.

 

I'm not so sure I can agree with Rotella = Garbage.
If you had some scientific facts to back that up I would not comment.
There are MANY , I mean MANY guys, companies, that use Rotella in all makes and models of diesel engines! It's not really a very (helpful) comment to post without adding some further information.
Texastech:....I have been posting questions on the other thread (5 pages long so far) about this (new) rating CK-4 as well as reading as much as I can to try to learn some FACTS so I might make a decision as to what oil to use for my next oil change.
As mentioned, It's very hard to (believe) much of what is being printed by EITHER FORD or SHELL (statements) about this new rating. Ford says NO, Don't use because of "wear results noted in tests". But no specific details. Shell says it's going to be "backwards compatible", So it can be used with any engine that called for CH, CI, CJ... (Just who are we supposed to believe?).
I don't trust them! Neither do I want to wear out my 2003 7.3 prematurely because I did not change old habits or study this enough.
I personally have been using the Rotella 15W-40 T4. It's convenient to get at any Wally World and some other autoparts stores.
It (was) rated to meet the WSS-M2C171-E that my OEM diesel supplement said I had to use, When it was a CH, CI, CJ. As those ratings went up they seemed to be (O.K.) because they were just doing (soot reduction) improvements (as I understood it). BUT this new "formula" seems to be something quite different. Designed to accommodate the newer 2003 1/2 and up engines with their requirement to meet new EPA specifications.?? You have to wonder if the grand design is to Phase out our older polluters by ruining them over a semi short/long period of time by the use of an inferior oil and a lot of mis information being disseminated. With my tinfoil hat on I will say it.....I do NOT doubt the possibility of collusion between the Govt. and the vehicle manufactures to do just such a thing!
Hat off now. Just looking for some straight forward information written in a COMPREHENSIVE but also CLEAR comprehensible English written word.
Hat back on......Wonder how much money is being made in licensing fees with this so called (new CK-4) oil designation and what oils meet it while still complying with the specification called out for at the time of vehicle manufacture. In this example the
WSS-M2C171-E. ???????
Any comments welcome and thanks in advance. DDT

 

This is the most updated list from ford.
https://www.fcsdchemicalsandlubrican...SSM2C171F1.pdf

 

Well look at that, T6 made it, just like the Shell press releases said it would

 

So it did I didn't even look at it when I posted the link it hadn't been updated since sometime in June. Shell was confidant it would make the cut at some point. Wonder if and when the delo will make it.

 

Mobil HDEO and Devlac 1 ESP 0W-40 are on the list, no way the common grades and higher branded oils don't make it. Probably just working through the lab procedures on the rest, since those are the only Exxon products listed.

EDIT: IDK why I thought you said Delvac. Delo 400 LE 54W-40 CJ-4 is still being restocked in stores, only the new version of the 400 SDE 15W-40 seems to even be CK-4 rated. Maybe they're behind in general, or had a bunch of stock to burn through. Delo 400 LE is still good to go for us old farts since the CJ-4 is the newest rating on the 5W-40 bottles.

 

NAPA has Valvoline PBE on sale for 19.99 a gallon through end of Sept.

 

Mike189677:
Thanks very much for that latest updated list of approved oils from Ford meeting
WSS-M2C171-F. I see my regular (easy to get anywhere across the country),
Rotella 15W-40 has finally been added. (Guess they paid their fee $$$ to Ford to get it on there). It's nice to have a list that long and growing BUT it really has to make me wonder just what testing they did on each & every one of these oils/brands/weights to determine they were (now) eligible to make the cut? I guess I will have to start sending samples off to Blackstone labs again for at least the next 3 or 4 cycles of oil changes to ensure they do not find any high levels of bad things.
I'm sorry, I just don't have much faith in this list or the "it's backwards compatible"
line they are giving us. Still don't know the details of why Ford was saying NOT to use ANY of the new CK-4 oils in Any of their engines back in 2016 statement...

" API CK-4
Ford will not be recommending the use of CK-4 motor oils in any Ford diesel engines,
new or old. Ford testing has shown some CK-4 type formulations have shown
inadequate wear protection compared to CJ-4 formulations developed and licensed
before 2016.

Then they go on to add a paragraph that just makes it more confusing because of the similarities in the terms " FA-4" (one of the NEW API designations of which Ford does NOT recommend any engines use , new or old).
And the specification, " Ford Material Engineering Specification WSS-M2C171-F1.
(The -F1 being the part that makes this whole thing confusing).
That Ford DOES recommend you use.
So I go to the local WallyWorld and look at the Rotella 15W-40 T4 triple protection...
As shown in the Ford list this is now (supposedly) an approved oil to use.
That list just updated 8-30-2017.
But on the back of the bottle, While there is a number of manufacturer Specifications listed. Caterpillar, Detroit, Volvo, and even International. There is NO MENTION of FORD or ANY of Fords Specific Specifications!
Specifically....Fords Specification...
Ford Material Engineering Specification WSS-M2C171-F1.
Yeah, I am probably going to go ahead and use the new Rotella 15W-40 (CK-4). But I am NOT going to feel very confident about it unless I get 3 or 4 good reports from Blackstone. But that's a LOT of wear miles on the valvetrain. And if I read & recall the old Ford report correctly, That was the wear issue they had taken notice of that caused them to NOT recommend the use of the CK-4 oils in ANY new or old engines.
One guy on another thread speaks of a brand of oil that they use for years and is still classified as a CH (IIRC) but also says it's an "off road oil" classification.
Anyone able to tell me more about what exactly that means? Obviously I understand "off road". What I don't get is what about the particular oil makes it classified that way. All this assumes the guy that posted that comment had any idea what HE was talking about! DDT

 

im going to add a zinc/phosphours additive . the reduction of these componds is what is driving up the wear.

 

Rotella T6 has been running in diesel engines from the Artic of Alaska to the tropics. It is, and has been, one of the best synthetic diesel oils for many many years.
I think this was just a case of Shell paying Ford to be on"their approved list" what ever that means..
