What is a multi-viscosity oil?

Multi-viscosity oil is designed to function effectively across a range of temperatures, which is essential for small engines that may operate in varying conditions. This type of oil has additives that allow its viscosity to change with temperature, providing better lubrication during both cold starts and hot operating conditions. This adaptability ensures that the oil remains fluid enough to form a protective film around engine components when the engine is cold while maintaining sufficient viscosity to protect the engine when it is hot.

Using a multi-viscosity oil helps to maintain engine performance and efficiency throughout different weather conditions, contributing to longer engine life and optimal operation. This versatility is why multi-viscosity oils are often recommended for engines, ensuring they meet the necessary standards for viscosity performance across fluctuating temperatures.
