The Mobil oil company was formerly known as The Socony - Vacuum Oil Company. They merged with Exxon in 1999 and formed Exxon Mobil. They mainly cover a wide range of automotive, industrial, aviation and marine oils.
Equivalent of Mobil SHC-32 is ARAL Aralub SKL 2, Castrol Product 783/46, Esso Beacon 325, FUCHS Renolit S2 or Renolit HLT2, Klober OSOFLEX TOPAS NCA 52 or PETAMO GHY 133N, Shell Aero Grease 16 oder 7. See page 5 of this document: http://nord.com/cms/media/documents/bw/B1042_DE_GB_FR_1207.pdf And on page 117 of this document http://www.watson-marlow.com/pdfs-global/spx-f-02.pdf The UK equivalent, Mobilith SHC-32 is no longer made. Beware of Aero greases, they tend to be more expensive. Can I ask you are you in the UK and have you managed to find a source for any of these yet? I am searching for some for our Earth Station Antenna.
