What are the benefits of using synthetic primary oil in a Harley?

This is because Harley engines have different requirements compared to other types of motorcycles. Secondly, the viscosity of the oil is important to consider. A thicker oil can provide better protection, but may also cause more friction and heat. A thinner oil may provide better performance, but may not offer as much protection. The climate in which the motorcycle will be ridden should also be considered, as this can affect the oil's viscosity needs. Additionally, the oil's additives should be evaluated. Some additives can increase performance or reduce wear, while others may not be necessary and can increase cost. Lastly, it is important to follow the manufacturer's recommendations for oil type and change intervals to ensure optimal performance and longevity of the motorcycle.
What is the recommended viscosity for primary oil in a Harley?
The recommended viscosity for primary oil in a Harley depends on the specific model and year of the motorcycle.

However, some models may require a different viscosity, such as the Sportster models which recommend using a 10W-40 viscosity oil. It is important to consult the owner's manual or a reputable Harley-Davidson dealership to determine the correct viscosity for your specific motorcycle. Using the recommended viscosity will ensure proper lubrication and protection of the primary chain and clutch components, ultimately prolonging the life of the motorcycle's engine.
