interesting...
now it is going to take hours to find out if this new oil has any positive or negative effect on a 6.0 :doh:
increased wear certainly sounds worrisome but is this due to oil getting too thin to do its primary job
or is it because no one runs motorcraft oil anymore :dunno:
I know my truck runs like crap on motorcraft but...

also diesel dave...
yea it sucks to have to wait for someone to go in and pay or get change but kind of a dick move if you ask me lifes short but not so damn short I cant wait a minute or to to pump fuel :doh:
just mho

I just bought enough Rotella T6 CJ-4 to last a year. Figured Ford and oil makers will have everything worked out well within that time frame.

CJ-4. I stopped at NAPA and picked up 6 gallons of Valvoline Premium Blue Extreme 5W-40 on sale for $18.99 a gallon. It was $28 the last time I bought it. They may be trying to clean out the CJ-4 to make room for CK-4.
I always get 5W-40 because it covers everything from severe cold to towing my 5th wheel. Valvoline gets me slightly better mileage than T6.

Smuggs you prefer the valvoline over the rotella? I'll be due an oil change pretty quick and had planned on using the rotella as that's what I used in my 6.0

At $18.99/gal, you bet I do! I've only used it for one OCI this summer, but it seemed to get slightly better fuel mileage. I've found threads that claim it helps with soot better than Rotella. I have no personal evidence and went back to Rotella just because I had it in my garage. I would be fine with Delo as well. T6 is just the most available, but not necessarily the best.

I have always used Dello 15/40 CJ4 diesel rated oil. I contacted Chevron lubrication division by email and they informed me they are not going to discontinue Dello CJ4 formula. Later I read on the Internet that they are coming out with a CK4 just like everyone else except they're going to also keep the CJ4 formula. I'm sure they eventually will get everything worked out to Ford's satisfaction and approval. Meanwhile I have 18 gallons of Dello and enough filters to last me for over a year.

I have been using Delo for some time now. Both my Kubota and truck like it. My Blackstone results have been better on the delo. I got about 8% better wear characteristics over the Rotella T6 i was running for years. Plus the Delo has about another 30% TBN life left after 8500 miles compared to the T6 as well.

I was a Rotella fan boy for long time. Delo has put it to shame IMO and per the oil samples.

I agree with the sentiments with regards to Rotella vs Delo. I used Rotella for quite some time... Oil analysis was always decent, but the engine was chatty. Switched to Delo because there was a sale and have not looked back. Oil analysis has Ben superior and my regen interval is longer now. I have been told Valvoline PBX is even better...I can never find it in stock at Napa.

It wasn't on the shelves at my NAPA, but asked at the counter. They had plenty in the back, but not enough room for it on the shelves. Surprised because it was also on sale at $10 off per gallon.

So if Ford rejected the ck-4 does that mean that the Motorcraft oil will still be made to cj-4 spec? That's what I always use.

I'm not seeing Delo on the interactive page yet. But, just because 12/16 was the release date for CK-4 doesn't mean everyone was ready yet. Plus Ford's spec was a little late to the party so a few may have gone back to the drawing board.
Chevron's response to Ford:
Chevron is moving forward with our transition to the new Delo® 400 API CK-4 and FA-4
products in all package styles as previously announced since a large part of the HDMO market
in North America will move to these products over time. Chevron, however, is committed to
ensuring that customers who drive Ford Diesel pickup trucks have access to Delo 400 products
that will protect Ford diesel engines.
As previously announced, we will continue to offer two API CJ-4 Delo 400 products in our
portfolio, Delo 400 LE SAE 15W-40 and Delo 400 SD SAE 15W-30, that meet Ford’s 6.7L engine
protection requirements:
 Delo 400 LE SAE 15W- 40 will still be available in bulk to our distributor channel
where it may be repackaged into drums and pails after December 1st, 2016.
 Delo 400 SD SAE 15W-30 will still be available in bulk, drum, pails and gallon jugs
after December 1st, 2016.
Chevron’s Next Steps:
Chevron will be working with Ford to submit candidate Delo 400 API CK-4 products for approval
under the new WSS specification once Ford opens it up for qualification testing. We will
communicate to the market through our normal channels once we have Delo 400 products
qualified against this new WSS specification.

The bottom line here is that several major oil brands DO NOT meet Ford's new specs for CK-4. I suggest you look for CJ-4 oils in those brands that you like. There is no good reason to go to CK-4 as yet. I had stocked up on Valvoline PBX CJ-4 in anticipation of this situation.

Was just in Walmart and saw the red cap with the CK-4 spec listed on it, most of the diesel oils had it. I was confused so I ended up here. I'm still not sure what was the best to buy in this situation, I went with the motorcraft. It's hard to imagine that was a bad choice, I'm going to have to figure this out before the next oil change. My wife is going to love this 😄 I wasn't planning in it, but I might have to renew my membership and go back to Amsoil like I was using years ago in a different truck. I'm concerned with switching at this stage of the game on a new rig with unknown history though. Why can't they leave stuff alone!?

They can't leave things alone because it's a moving target. CK-4 is just the latest evolution of oil specs to comply with increasing strangulation of emissions systems. Less phosphorus, cleaner DPF's and air.
That being said, no reason to switch to AmSoil unless you want it. Rotella currently meets the spec, many other oils do as well. Wal-Mart has it, farm supply stores, all the auto parts chains.
Delo has products that meet the spec, CJ-4 400LE, and the 15w30 Severe Duty.
Any CJ-4 is fine. There is a bunch of the Valvoline out there still, both 5w and 15w 40's. Your local Cat or JohnDeere dealer would be another source of CJ-4.
Every other manufacturer is supporting CK-4: Cummins, DMax, Navistar, Volvo. Literally every OTR, heavy duty, and backyard tractor manufacturer is moving on with CK-4, but Ford has a special metal in the valvetrain that is wearing away with these oils? In a mature design engine? And with CK-4 being announced well in advance, and a long time in development? Seriously? This is a Ford thing, not a Chevron, Shell, Valvoline, Citgo, Mobil thing.
Ford has always had a goofy attitude toward fluid recommendations. The 6.7 is no different. What I can't wrap my mind around is their requirement of a 40 weight with any percentage of bio fuel, when the 30 weights are just so stout, and so good. The Scorpion is filled with 10w30 from the factory. Are we really expected to believe the plant has 100% petroleum diesel at assembly, and that the dealer changes the oil to a 40 weight at delivery to support the states that require a % of bio fuel in diesel as part of a state program. But the end user is expected to have this little detail in place if there is a question on warranty? I call bovine scat.
But to keep them happy, my choice is Valvoline Premium Blue, CJ-4, 15w40.
9.99 a gallon at Menards.

My concern is that my truck is 18 years old, and the HEUI system design is probably closer to 25 years old. The new oil specs could care less how well it works for our trucks (ford included) Each new generation of diesel rated oils seem to stray further from the original our trucks were designed to run for the sake of emissions and such. The only reason I mentioned Amsoil is I think they still offer a diesel oil which is CI-4 rated which should be closer to the original specification. This is probably all over hyped worry, and 5 years from now we will be talking about how great these new oils turned out to be, but I can't help but research and over think things. Part of the reason I bought andother 7.3l in the first place. 0:)

You really don't need to find a CI-4. CJ-4 is really a superior oil in nearly every area that an oil has to perform. Yes, slightly lower TBN by design in CJ-4, but ULSD introduced about the same time isn't putting stuff in the oil anymore to deplete TBN.
CJ-4 had a lot of thought and effort put in it. Likely the most robust additive packs ever are in CJ-4, reducing overall wear. CJ-4 was pretty much the beginning for extended drain intervals by Cummins, the oil just holds up better than CI-4. If you find a CI-4 and feel like you want to run it, no harm done. But CJ-4 really has proven to be a better overall formula than CI. And for most manufacturers, CK-4 is another improvement. Why Ford has their panties in a wad is a little confusing. If they have parts in the valvetrain that are that highly stressed that a 200ppm of phosphorus is the make or break point, Ford needs better design management, new engineers, or different metallurgy.
