It balances factors such as bearing clearances, internal pumping losses, and desired fuel economy. A multi-grade oil, such as 10W-40, is engineered with specific additives that allow it to act like two distinct oils: one optimized for cold starts and another designed to remain stable at high heat.

The number preceding the 'W' indicates the oil’s cold-temperature viscosity, with lower numbers flowing more easily. Viscosity itself refers to a fluid’s resistance to flow.
Deviating from this recommendation can compromise the oil film strength or hinder proper lubrication, potentially leading to increased wear or reduced efficiency. Modern engineering has largely replaced these with multi-grade formulations.

This physical property dictates how easily oil flows at various temperatures, directly impacting engine protection, fuel efficiency, and overall performance. Think of it like this: water has low viscosity and flows freely, while honey has high viscosity and moves slowly.
