Using an oil that is too thin in a high-mileage or performance engine can lead to increased oil consumption and pressure loss. The number preceding the 'W' indicates cold-temperature performance, while the number following it reflects viscosity at high operating temperatures.
How Real World Tests Measure Engine Oil Viscosity Performance
The Science Behind the Flow Engine oil viscosity is manipulated through the base oil stock and a complex additive package known as viscosity modifiers. Driving Conditions and Climate Considerations Geographic location and driving habits play a significant role in viscosity selection.
Understanding engine oil viscosity is fundamental to responsible vehicle ownership. Conversely, using a viscosity that is too thick in a modern, fuel-efficient engine can cause poor fuel economy and inadequate lubrication during the critical warm-up phase.
How Real World Tests Measure Oil Flow and Protect Your Engine
The Role of the "W" Factor The "W" in these ratings stands for Winter, representing the cold-cranking simulator (CCS) viscosity test. 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.
