Decoding the Viscosity Grade The first number, prefixed with a "W," indicates the oil’s cold-weather performance. For example, a 10W-40 oil will be thicker at high heat than a 10W-30 oil, offering a more robust protective layer under heavy loads.
Oil Viscosity Chart Performance Benefits
Understanding oil viscosity is essential for maintaining any engine or mechanical system that relies on lubrication. Industry Standards and Testing Reputable oil manufacturers adhere to strict standards set by organizations such as the American Petroleum Institute (API) and the Society of Automotive Engineers (SAE).
How Temperature Affects Oil Viscosity Oil behaves differently in cold conditions compared to hot operating temperatures. When cold, oil thickens and flows slowly, which can make a cold engine difficult to start and increase initial wear.

Conventional Lubricants The base oil used in the formulation plays a significant role in how the oil behaves on the viscosity chart. This thermal sensitivity is why the oil viscosity chart is split into two numbers, such as 5W-30, representing performance in both low and high temperatures.
