In re: The Prof's friend Rob and ZDP being *totally* removed or not.
Unfortunately the study was done on diesel oils, and as I'm sure you are aware,
diesels only recently acquired cats (as compared to autos).
(No comparison to specific gasoline engine rated oils and PPM of zinc - although the diesel oils would/should still meet gas engine specs)
As you indicate, even the (new) CJ-4 rated oils (there were only four CJ-4 oils
of the 21 tested) had PPM of Zinc at a low of 947 to a high of 1268.
The CI-4 and CI-4 Plus oils had PPM's with a low of 1028 to a high of 1583.
(Unfortunately, "we" won't find those anymore at the parts store).
The guy contracted for the tests was: "John Martin, formerly -25 years of service - of Lubrizol Corporation."
Then, lots of gee-whiz resume stuff, and lastly,
"he is a recognized lubrication consultant to both the racing (NASCAR and NHRA) and the trucking industries."
Lots of info on base stocks and syn vs mineral vs part syns.
An interesting statement (his) in that area which would pertain to generators:
"I use partial synthetics in my motorcycles because air-cooled engines are subject to greater temperature variations than water-cooled engines."
