FIGHTS ENGINE WEAR

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
