Absolute viscosity — Dynamic viscosity

Absolute viscosity — Dynamic viscosity What is motor oil absolute viscosity? Absolute viscosity is different than kinematic viscosity. While kinematic viscosity measures how a motor oil flows under gravity, absolute viscosity measures how well a motor oil behaves during cranking and how well it pumps when cold. It’s not a flow test. Instead, it’s a test performed by cranking or pumping the motor oil. In simple terms, a motor oil that has a higher absolute viscosity would be harder to stir than another motor oil that’s easier to stir at … Read More
