The second number reflects the oil’s thickness at the engine’s normal operating temperature. These bodies test oils to verify that they meet the viscosity claims printed on the label.
Oil Viscosity Chart Comparison Guide: Understanding the Differences
Decoding the Viscosity Grade The first number, prefixed with a "W," indicates the oil’s cold-weather performance. Using oil that is too thick can result in poor fuel economy and sluggish engine performance, while oil that is too thin may fail to protect against metal-on-metal contact.
This innovation simplifies maintenance and provides year-round protection regardless of climate fluctuations captured in the oil viscosity chart. Modern multi-grade oils have largely replaced these, as they utilize advanced additives to mimic the benefits of multiple grades in one product.

This certification provides consumers with confidence that the oil viscosity chart reflects real-world performance and that the product will deliver the protection it promises. When cold, oil thickens and flows slowly, which can make a cold engine difficult to start and increase initial wear.
