Dynamic viscosities for motor oils SAE 10 to 50 - temperature range 0 - 100 deg C
Viscosity of lube oil is determined by the Society of Automotive Engineers (SAE).
Lube oils can be multigrade or monograde where multigrade oils fulfills two viscosity specifications. Example SAE 10W-40 where 10W refers to low-temperature - or winter - viscosity and 40 refers to the high-temperature - or summer - viscosity.
|Dynamic Viscosity (N s/m2)|
- 1 N s/m2 = 1 kg/(m s) = 1 Pa s = 1000 cP
