SF/SH oil

[MolaKule]

Someone in the Additives section wanted to see an analysis so here is an analysis
of a current SF/SH oil:

10W40 SF/SH

Metal
Iron (Fe)
Copper (Cu) 0
Chromium (Cr) 0
Aluminum (Al) 1
Lead (Pb) 0
Tin (Sn) 0
Silicon (Si) 3
Sodium (Na) 0
Potassium (K) 3
Molybdenum (Mo) 0
Phosphorus (P) 800
Zinc (Zn) 750
Calcium (Ca) 1500
Magnesium (Mg) 6

TBN 8.3
K. Vis 13.4

NOTE: In the original formulations, the Phosphorus and Zinc were in the 1,300 and 1,200 ppm levels, respectively. Magnesium was more like 300 ppm or higher.

So does this mean that it won't meet the SJ or SL specs, because of the performance requirements and not the phosphorus limit?

Here is another dedicated SH still available

Conoco HD Fleet Supreme 10w30

Phosphorus 2217
Zinc 1893
Magnesium 467
Calcium 4517
Silicon 5
Vi @ 100C 11.11

-45F Pour Point

In my SF post, the oil does not have the detergent/dispersant package necessary for cleaning modern engines. The SL zddp addpack is low since they are trying to fly it safe in case someone puts this stuff into a modern engine. I.E., no one can come back and say this damaged their catalytic converter.

In Motorbikes example above, with the exception of the modern Calcium add,

this oil is closer to the original SF/SH formulation.
