Decoding the Viscosity Grade Viscosity is the fundamental property indicated by the numbers on oil. The goal is to find a balance where the oil is fluid enough to protect the engine during cold starts, yet thick enough to sustain a strong oil film under the intense heat and pressure generated during operation.
Balancing Oil Numbers for Economy and Performance
Reading Industry Standards and Specifications Beyond the viscosity numbers, the labels on oil containers display various performance certifications. An oil that is too thick can create excessive drag on engine components, reducing fuel efficiency and making it harder for the engine to turn over.
As a result, synthetic blends or full synthetics frequently maintain their viscosity more effectively in both extreme heat and cold. Understanding these codes helps you verify that the selected oil provides the necessary protection for your vehicle.

This number reflects the oil's ability to maintain a protective film at high heat. This dynamic behavior is precisely what the two-number system is designed to describe.
