Why is Honda oil 0w20?

Honda recommends 0W-20 oil for its vehicles primarily due to its optimal viscosity for fuel efficiency and engine performance, especially in varying temperatures. This oil grade provides better cold-start performance and reduces internal friction, enhancing overall engine efficiency. Additionally, 0W-20 oil meets the specifications for modern Honda engines, supporting their design for lower emissions and improved fuel economy. Using the recommended oil helps maintain engine longevity and performance.
