Here are a couple of quotes from Exxon regarding their Moly EP type greases (emphasis added):

RONEX EXTRA DUTY MOLY 2 is recommended for high load applications at slow-to-moderate speeds, including applications in the paper, construction, and mining industries, as well as off-highway vehicles operating at 35 mph or less. RONEX MP, with its much lower base oil viscosity of 767 SUS, is designed to meet a wider range of high-speed industrial and automotive bearing applications, including wheel bearings in on-highway use.

Beacon EP 2 Moly is suitable for plain bearings and gears. It also can be used in rolling contact bearings, but is not generally recommended for high-precision rolling contact bearings because of the possibility of molybdenum disulfide building up in the clearances.

Quotations from marketing tech info is best taken with a grain of salt. If some one has the technical know how to properly interpret information then a different picture emerges. Very few technically competent people will ever just take a few quoted words from a promo sheet on the net and accept it verbatim. Again I suggest that when some one expresses an opinion they need to give some indication of their expertise in the field.
At the end of the day we have some one who has openly provided personal experiences of the use of certain products, has stated where the recommendations to use it came from, has given details of their Professional qualifications & previously provided proof of that V/S no details of back ground, some copy and paste from promo sites on the net not even details of what cars they own.
Unfortunately I have seen this sort of thing before on here.
I will continue to use the products that are recommended to me by competent properly educated and trained professionals.
