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.

Motor oil viscosity

Dynamic Viscosity (N s/m²)
SAE	Temperature (^oC)
SAE	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
