The Role of the "W" Factor The "W" in these ratings stands for Winter, representing the cold-cranking simulator (CCS) viscosity test. The superior temperature resistance of synthetics allows for better protection in turbocharged engines and during sustained high-speed driving.
Mastering the Basics of Engine Oil Viscosity
The number preceding the 'W' indicates cold-temperature performance, while the number following it reflects viscosity at high operating temperatures. Selecting the correct viscosity grade is not merely a matter of preference; it is a critical decision that affects every aspect of engine performance and reliability.
This physical property dictates how easily oil flows at different temperatures, directly impacting cold-start protection, fuel efficiency, and the longevity of your engine’s internal components. At a molecular level, polymers are added to the base oil to counteract the natural thinning that occurs when the engine heats up.
Decoding the Numbers Behind Oil Viscosity Ratings
This measurement determines how resistant the oil is to flow when subjected to extreme cold. Conventional Viscosity Performance Synthetic oils often outperform conventional alternatives in viscosity stability.
