For a 1993 Harley-Davidson Fat Boy, the best oil is typically a high-quality 20W-50 motorcycle oil specifically designed for air-cooled V-twin engines. Look for oils that meet or exceed the API (American Petroleum Institute) standards and are suitable for wet clutches. Synthetic options can provide better protection and performance, especially in extreme temperatures. Always check your owner's manual for manufacturer recommendations.
