Engineered for maximum performance in V-twin engines, motorcycle transmissions and primary chaincases. Protects against extreme heat. Wet-clutch compatible. Advanced synthetic formulation resists viscosity loss to keep critical components clean and protected.

See the Product Data Bulletin for full details.

REDUCES WEAR & DEPOSITS

• Resists viscosity breakdown 6X better than Harley-Davidson SYN3 for improved protection against compensator and transmission gear wear.¹
• Contains heavy treatment of anti-wear additives to reduce wear in the most extreme operating conditions.
• Fortified with maximum levels of oxidation inhibitors to fight deposits for maximum engine compression and power.

Resists Viscosity Breakdown

AMSOIL resists viscosity breakdown 6X better than Harley-Davidson SYN3 for improved protection against compensator and transmission gear wear.¹

WITHSTANDS EXTREME HEAT

• Formulated with naturally heat-resistant synthetic base oils that resist oxidation in extreme summer heat and during strenuous stop-and-go rally or parade traffic.
• Unique additive system helps keep engines clean and running efficiently in the toughest riding conditions.
• Prevented piston-ring sticking and protected against piston scuffing after 1,000 miles (1,609 km) of extreme-heat dyno testing during which cylinder temperatures reached 421°F (216°C) (see video below).

PROTECTS TRANSMISSIONS & PRIMARIES

• Shear-stable formulation resists thinning from mechanical activity to protect transmissions and primaries from wear.
• Performs like a gear lube without the negative effects of extreme-pressure additives.
• Delivers the convenience of one lubricant for all three sumps.
