Fe 2

AL 2

B 33

Na 5

MG 10

Ca 1965

P 1355

Zn 1504

All other elements 0

Visc. at 100c= 15.7

TBN= 9.6

Somewhat surprised by the Phos and Zinc levels.

Not surprised by Na and Ca numbers.

Put up some good numbers in a 6.0 Super Duty I will post shortly.
 
There is a previous VOA in this section that shows much lower levels of P and Zn, but It's by Blackstone and a lot of there VOA additive levels have looked low lately.
 
I e-mailed Shell and asked them what the Zinc and Phosphorus levels were of the CJ-4/SM Triple Protection Rotella T. They said:

"Shell Rotella T Multigrade Oil SAE 15W-40 with Triple Protection
Technology, our API CJ-4/SM specification product, typically contains about 1200 ppm zinc and 1100 ppm phosphorous as manufactured."

From the horse's mouth.

I recognize one may choose to believe that or not. I'm less inclined to believe they'd lie about something like that.

Would that read as .11%/mass for phos and .12%/mass zinc ?
