- Naturally strong base oils resist viscosity loss due to mechanical shear.
- Develops a tough lubricating film that protects engine parts, even in high-heat, high-rpm conditions that break down other oils.
- Contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions, guarding against compression loss for maximum power and engine life.
EXCELLENT ANTI-RUST PERFORMANCE
- Fortified with potent inhibitors that guard against damaging rust and corrosion.
- Protects engines during use and during inactivity or long-term storage.
NMMA CERTIFIED
- Certified by the National Marine Manufacturers Association (NMMA) for use in four-stroke outboard motors.
