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) | ||||
|---|---|---|---|---|
| SAE | 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
