What Are The Different Grades of Oil?
Engine oil comes in various viscosity grades, which determine how the oil flows at different temperatures. For example, a 20W-50 oil is thicker and flows slower compared to a 10W-40 oil. The two numbers in the oil grade signify its viscosity at cold and hot temperatures respectively. For instance, in a 20W-50 oil, ’20W’ denotes its viscosity in cold weather, and ’50’ indicates its viscosity at 100°C (212°F).
How Do They Impact Engine Longevity?
The viscosity grade of an oil is crucial to a motorcycle engines longevity. A high-quality oil minimizes engine wear, keeps the engine clean, ensures optimal performance, and extends the engine’s life. Synthetic oils, due to their enhanced heat tolerance, are often recommended for air-cooled engines, like those in Harley Davidson motorcycles. They provide superior wear protection and keep the engine clean and deposit-free.
What Oil Does Harley Davidson Recommend?
Harley Davidson’s oil recommendations vary depending on the engine type. Each engine has its unique characteristics and may require a specific type of oil for optimal performance and longevity. However, it’s generally recommended to use synthetic motorcycle oil for maximum longevity and optimum performance.

- Extended Oil Life
Advanced Engineering for Extreme Conditions
Synthetic oils are specifically engineered for extreme conditions. Their formulation maintains consistent viscosity in varying temperatures, making them perfectly suited for the air-cooled engines of Harley Davidson motorcycles, which often operate under high heat.
Unmatched Engine Protection
The molecular uniformity of synthetic oils ensures a stronger protective film on engine components. This is essential for reducing wear and tear in Harley engines, known for their high torque and high-stress operation.
Enhanced Performance and Efficiency
Designed to minimize friction more effectively than conventional oils, synthetic oils lead to smoother engine performance and throttle responsiveness. This reduction in friction may also contribute to improved fuel efficiency, a significant advantage for long rides, a reduction in oil consumption over time.
Pioneering Formulations
Synthetic oils are developed with the unique demands of V-Twin engines in mind. These oils provide superior protection against heat, prevent deposit formation, and reduce wear through the use of friction modifiers, ensuring you have maximum protection and your Harley’s engine operates at peak performance.
Extended Oil Life
Synthetic oils have a slower breakdown rate compared to conventional oils. This means longer intervals between oil changes, saving both time and resources, and contributing to a reduced environmental footprint.
