[ChiTDI]

Expected the TBN to be higher.

 

[salesrep]

The retention of the TBN is outstanding. Which is what really counts.

 

[Johnny]

Agree with salesrep, but arn't those P and Z numbers a little high for an CJ-4 SM oil?

 

[INDYMAC]

Does 15w40 grade fall under SM ZDDP restriction requirements?

 

[addyguy]

Nice oil. Lot, lot more moly than I though would be used.

 

[REDDOG]

CJ-4 limits phosphorus to 1200. Ash is limited to 1%.

 

[JAG]

Nice antimony amount! Moly too but that is well known.
The TAN is higher than I'd expect.

 

[White_Buffalo]

The series 7000 15w40 has show great UOA results for my 7.3L PSD.

 

[Jaymus]

The P and Z seem high, and the Ca seems low. Is it just me?

 

[Johnny]

The calcium is made up by the 862 ppm of magnesium they are using.
