I'll tell you what they've done. They've taken an oil I've run successfully for years, and turned it into some kind of a wimpy near-beer.

From Polaris Laboratories:
KV100: 14.6 cSt
TAN: 2.68
Silicon: 5 ppm
Sodium: 3
Potassium: 2
Titanium: 1
Boron: 186
Magnesium: 80
Calcium: 1978
Phosphorous: 944
Zinc: 1109

These are all the metals that were present. Where is Moly?
The zddp content has really dropped off.
Magnesium is almost gone, compared to the previous formulation.
This doesn't look like a long life oil anymore.

I think I need to start considering alternatives.

It's not surprising right? Environmentally friendly has somehow beat superior protection, and we have to live with the results of this policy.

Is the batch you test dual rated for gas engines and SN? Or still SM?

And is there a way you can change the title so it says "Roellta T6" instead of RT6? (for future search purposes -- we don't all know the same acronyms)

I don't think rotella ever moly. Delo has moly. The boron makes up for the lack of zddp.

Before anyone else parrots the nonsense...
"There are things that don't show up in an oil analysis."
I agree with A_Harman. CK-4's look weak, and whether or not things show in an analysis or not, what we have judged by for a long time is long gone.
I must have missed the "Save the DPF's" flyers somewhere....

So can you just spike the oil with a good zddp additive? Or is that not the same?

Yep weak. Still p!sses me off how they snuck this new CK4 in their CJ4 bottles for months knowing that Ford was telling their diesel customers not to use the CK4. I was a loyal RT6 guy - never again.

OP, where is your objective evidence to substantiate your claims that it is not a long life oil, or that it won't protect as well? If it is meant to be environmentally friendly, if anything, it will be a longer life oil. I don't see any current specs being less stringent than older ones...

I get it if you have some older vehicles, the zddp and flat tappet cam issue may be a concern...

I dont understand why you are complaining. In the UOA you posted your wear metals are lower than previous samples. Other than a slightly lower TBN, the oil is working just fine.

Plating an engine only work if wire touch (main ground isn't enough to achieve this. Yes oil maker had to reformulate. We all see how oil do from now on with all electrical wire air gaped

Didn't we all agree never to mention UOA metals as valid indicators of wear ever again?...I could have sworn....

Note the difference in P and Zn, between the UOA and this VOA.
