A higher number generally indicates a thicker oil that forms a more robust lubricant film, which is necessary for engines with high loads or precision clearances to prevent metal-to-metal contact. Decoding the Numbers: What Viscosity Really Means The primary function of oil is to create a thin, slippery film between moving metal parts, preventing friction and wear.
How Oil Weights Explained Impact Engine Performance and Longevity
Oil weights explained starts with recognizing that viscosity changes with temperature. The Cold Weather Factor: The "W" Rating The letter "W" in a designation like 10W-40 stands for "Winter," and it specifically indicates the oil's cold-flow properties.
Matching Oil to Your Engine and Driving Habits Selecting the correct oil weights explained requires looking beyond the shelf and considering the specific demands placed on your engine. The standardized system used to measure this behavior is defined by the Society of Automotive Engineers (SAE), and it is the key to interpreting those cryptic codes.
How Viscosity and Temperature Affect Engine Performance
Conventional oils are refined from crude oil and contain a complex mixture of hydrocarbons, which can lead to more temperature variation in viscosity. Choosing the correct winter rating is essential for preventing wear during cold starts and ensuring the oil reaches all parts of the engine promptly.
