High Temperature-High Shear Viscosity (HT/HS)
HT/HS is a measure of dynamic viscosity, it represents the oil’s thickness within the vital hydrodynamic bearings of an engine. It is the most important measure of how well the oil will perform as a hydrodynamic lubricant. HT/HS is measured at 150°C which is a worst-case temperature for most engines. The higher the HT/HS, the stronger the hydrodynamic film in the engine’s bearings. Thus, the correct HT/HS is more important than the KV100 (SAE Grade) when selecting oil.
