These chemical compounds are mixed into the base oil to enhance its capabilities. Motor oil is the lifeblood of any internal combustion engine, performing a complex set of duties that keep moving parts functioning smoothly.
Understanding Motor Oil Cold Flow Properties
This is why motor oil is labeled with a code such as 5W-30 or 10W-40. The "W" stands for winter, and the number before it indicates the oil's cold-weather flow.
These base oils are typically refined from crude oil or synthesized in a laboratory, and they dictate the basic viscosity and thermal stability of the final product. Oil needs to be thin enough to flow quickly on a cold start to provide immediate lubrication, but thick enough to maintain a film strength when the engine is hot and under stress.
Understanding Motor Oil Cold Flow Properties and Viscosity
The lower the number, the better the oil flows in cold temperatures. Understanding Viscosity and Grades One of the most important characteristics of motor oil is its viscosity, which is its resistance to flow.
