cSt oil refers to oil viscosity, specifically measured in Centistokes. It is a common unit used, especially when reporting the kinematic viscosity of motor oil at high temperatures.
In simpler terms, the cSt value indicates how easily a motor oil flows at a specific temperature.
Here's a breakdown:
- cSt stands for Centistokes. This is the unit of measurement for kinematic viscosity.
- Kinematic Viscosity describes a fluid's resistance to flow under gravity.
- Motor Oil Application: The cSt value is particularly important for motor oil because it indicates how well the oil will lubricate engine components at operating temperatures. A specific testing device measures how long it takes a fixed amount of oil to flow through a precisely sized opening.
