AMSOIL is a well-regarded brand in the world of synthetic lubricants and many Harley-Davidson owners have reported good results using their products. However, it’s always a good idea to consult with your motorcycle manufacturer to determine the recommended oil specification for your specific model and engine type.
Harley-Davidson has specific oil recommendations for their engines, and they often recommend using a 20W-50 weight petroleum-based oil or a synthetic blend oil. The company also has its own branded engine oils that are designed to meet their specifications.
In summary, while AMSOIL is a high-quality synthetic oil, it’s important to follow the manufacturer’s recommended oil specifications for your specific Harley-Davidson model to ensure the best performance and longevity of your engine.
