Honda recommends a "high quality molybdenum disulfide grease" when repacking the CV joints on a 1991 Civic DX. However, I have been unable to find any suitable grease with 3% MoS2 that has a NLGI viscosity of 1, while there are many suitable greases with NLGI viscosity of 2. Do you know of any reason why #2 grease would not be suitable in this application.
Question # 2. A new C-V joint grease recommended by major refineries and reportedly used as OEM grease by Ford and NKG contains no MoS2. Do you know whay that EP additive have been dropped?

From day one of owning my vehicles, I have exclusively used Mobil-I synthetic grease on my CV joints and wheel bearings, my Accord V6 with 56,0000 miles is still going strong and so is my Gurkha with 170,000 miles. The Gurkha does heavy work in water logged areas and the Mobil-I holds up pretty well.

Hi Dennis,
I saw assortment of Chevron Lubs and found two products are “designed to lubricate the constant velocity (CV) joints of front wheel drive cars”. These greases have polyurea thickener and heat-stable EP agents and contain no MoS2 (greases have blue and cream color). Greases have NLGI 1 ½, -40 to 177 °С operating temperature ranges, compatibility with common elastomers and spec GM and GKN.
I think that more 10 years ago the car manufacturers requires the greases with Moly for these applications. But now there is no need to moly - greases no leak from joints, have high drop points and good thermal stability (moly has good efficiency when it uses for very dirty parts - idlers and rollers of tracked equipment - or for parts which didn't hold grease - fifth-wheel device. And may be grease’s manufacturers are stop to use MoS2 for these applications.

Mikhail: Thanks for the explanation why MoS2 is no longer added to CV joint greases. I saw the same greases you mentioned on the Chevron website and comparable greases on the Mobil website. But it is impossible to purchase those CV joint greases in small quantities e.g 14 oz cartridges or 5 lb pails. I have decided to use Mobil CM-P a NLGI #2 grease with 3% moly and 320 on the ASTM D 445 test because I can purchase it in cartridges.
