The number preceding the 'W' indicates the oil’s cold-temperature viscosity, with lower numbers flowing more easily. The Temperature Dependence of Oil The true complexity of motor oil viscosity lies in its reaction to temperature.
How Viscosity Index Improver Additives Work
Understanding motor oil viscosity is fundamental to responsible vehicle ownership. Modern engineering has largely replaced these with multi-grade formulations.
Tight internal tolerances in engines, particularly those with variable valve timing or turbochargers, often demand specific, low-viscosity oils to function correctly. Drivers in extremely hot climates or those who frequently tow heavy loads might benefit from a slightly higher high-temperature viscosity to maintain a robust oil film.
How Viscosity Index Improver Additives Work
Deviating from this recommendation can compromise the oil film strength or hinder proper lubrication, potentially leading to increased wear or reduced efficiency. Think of it like this: water has low viscosity and flows freely, while honey has high viscosity and moves slowly.
