Viscosity Ratings and Temperature Performance Decoding the Numbers on the Label Viscosity, often referred to as the oil's "thickness," is the primary characteristic used to grade engine oils and is denoted by numbers such as 5W-30 or 10W-40. Selecting the correct viscosity grade is crucial, as using an oil that is too thin can lead to inadequate lubrication, while an oil that is too thick can increase fuel consumption and hinder cold-weather starts.
Regular Engine Oil Cold Climate Recommendations: Viscosity and Performance
Regular engine oil serves as the lifeblood of any internal combustion engine, performing a multitude of critical functions that extend far beyond simple lubrication. Furthermore, modern formulations contain surfactants that encapsulate contaminants, dirt, and combustion byproducts, suspending them so they can be captured by the oil filter.
Without this cleaning action, these particles would circulate through the engine, causing abrasive wear and reducing efficiency over time. Modern formulations also contain detergents and dispersants that keep the internal components clean by preventing the accumulation of harmful deposits and sludge.

The "W" stands for winter, indicating the fluid's cold-temperature flow characteristics, while the number preceding it signifies how easily the oil flows at low temperatures—the lower the number, the quicker it circulates on startup. Using the manufacturer-recommended grade ensures that the engine runs smoothly with minimal drag, optimizing combustion efficiency and helping the vehicle meet emissions standards without sacrificing durability.
