Motor Oils - Dynamic Viscosities
Dynamic viscosities for motor oils SAE 10 to 50 for temperatures ranging 0-100 oC.
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.
SAE | Dynamic Viscosity (N s/m2) | |||
|---|---|---|---|---|
| Temperature (oC) | ||||
| 0 | 20 | 50 | 100 | |
| 10 | 0.31 | 0.079 | 0.020 | 0.005 |
| 20 | 0.72 | 0.170 | 0.033 | 0.007 |
| 30 | 1.53 | 0.310 | 0.061 | 0.010 |
| 40 | 2.61 | 0.430 | 0.072 | 0.012 |
| 50 | 3.82 | 0.630 | 0.097 | 0.015 |
- 1 N s/m2 = 1 kg/(m s) = 1 Pa s = 1000 cP
