Hi folks, doing some oil research this morning and came across this page:
Zinc Level of the Two 15W-50 Mobil 1 Products

It is a statement from Mobil about the zinc and phosphorous levels in both the gold cap and silver cap products. They assert that both have 1200-1300 ppm zinc concentration, good to hear since I have been running the silver cap stuff in my 560. There was some discussion a while back about the silver cap bottles not having the proper amount of zinc.

I assume the date on this statement is recent since I've not run across it yet. There is no reason to doubt it, but I suppose an independent analysis would be absolute on the matter.

FWIW....
