The 2013 Honda Gold Wing GL1800 requires a 10W-40 motorcycle engine oil that meets JASO MA/MA2 and API SN or higher; the bike also uses a separate final-drive gear oil (typically 80W-90).
The Gold Wing’s oil needs reflect its design as a large, liquid-cooled, shaft-driven, six-cylinder touring motorcycle with a wet clutch. Selecting the right oil helps protect the engine, clutch, and shaft-drive system while ensuring smooth performance across climates. Below is a practical guide to understanding the specification and how to choose oil for your 2013 Gold Wing.
Engine oil specifications
For the GL1800, Honda specifies a four-stroke motorcycle engine oil that can be synthetic or synthetic-blend, provided it meets industry standards suitable for motorcycles with a wet clutch. The standard viscosity most commonly used is 10W-40, but climate can influence the choice. Oils should meet JASO MA or MA2 and API SN (or higher) requirements to ensure proper clutch performance and wear protection. Never use regular automobile oil or motorcycle oils with friction modifiers that could affect the wet clutch.
Key considerations when selecting oil are summarized here to help you pick confidently.
- Viscosity: 10W-40 is the standard, with 15W-40/15W-50 or 20W-50 acceptable in very hot climates or extreme conditions, if the manual allows.
- Standards: Look for JASO MA or MA2 and API SN (or newer) certification on the bottle.
- Type: Choose a high-quality 4-stroke motorcycle oil; synthetic or synthetic-blend oils are commonly recommended for the Gold Wing.
- Clutch compatibility: Avoid oils with friction modifiers or “energy-saving” additives that could cause wet-clutch slip.
- Car oils: Do not use car engine oils; motorcycle-specific oils are formulated for the transmission/clutch within a single case.
Conclusion: For most riders, a reputable 10W-40 motorcycle oil meeting JASO MA/MA2 and API SN or higher is a reliable choice, with climate-based adjustments as needed. Always verify with the owner’s manual or a Honda service professional if you ride in extreme conditions or have specific maintenance guidelines.
Final-drive oil and other considerations
The Gold Wing uses a separate final-drive system that requires its own gear oil. The typical specification is an 80W-90 GL-5 gear oil, used in the final drive, not the engine oil. Do not mix final-drive oil with engine oil, and follow the service intervals outlined in the owner’s manual for replacement. If you’re unsure, consult your manual or a Honda-certified technician for the exact capacity and procedure.
Summary
In short, a 2013 Honda Gold Wing takes 10W-40 motorcycle engine oil that meets JASO MA/MA2 and API SN or higher, with a separate final-drive gear oil (usually 80W-90). Choose a high-quality motorcycle oil (synthetic or synthetic-blend) and avoid car oils or oils with friction modifiers that could affect the wet clutch. Always refer to the owner’s manual for precise specifications, capacities, and service intervals.
