What is 5W40 Oil?
Before we dive into the compatibility of 5W40 oil with various engines, it’s essential to understand what 5W40 oil is. 5W40 oil is a type of multi-viscosity oil that is designed to provide excellent lubrication in a wide range of temperatures. The “5W” in 5W40 oil refers to its winter viscosity rating, which means it has a low viscosity of 5 during cold temperatures. This allows for easier engine starting and better lubrication during cold weather conditions.
The “40” in 5W40 oil refers to its high-temperature viscosity rating, which means it has a higher viscosity of 40 during hot temperatures. This provides better lubrication and protection for your engine during high-temperature conditions. 5W40 oil is a popular choice among car owners because it provides a good balance between low-temperature performance and high-temperature protection.
