Shell Tellus S2 MX 32 is the ISO VG 32 grade of the Shell Tellus S2 MX range of high-performance hydraulic fluids based on Group II base oils, which deliver outstanding protection and performance in most industrial operations and mobile equipment. They resist degradation under demanding temperature and mechanical stress conditions and help prevent the formation of deposits that reduce hydraulic system efficiency. Its kinematic viscosity is 32 cSt at 40 °C and 5.4 cSt at 100 °C, with a viscosity index of 105. The data sheet lists it against Bosch Rexroth Fluid Rating RDE 90245, Parker Denison HF-0, HF-1 and HF-2, Eaton E-FDGN-TB002-E, Fives Cincinnati P-68, ISO 11158 HM, DIN 51524 Part 2 (HLP), ASTM D6158 (HM) and SS 15 54 34 AM.
