SEVERE GEAR 75W-85 Synthetic EP Gear Lube
AMSOIL SEVERE GEAR 75W-85 is a premium-grade synthetic gear oil specifically engineered for maximum performance in severe-duty applications. It maintains its viscosity for long-lasting protection against metal-to-metal contact. Its proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring.
Key Benefits
- Advanced protection against wear, pitting and scoring
- Controls thermal runaway under high-stress conditions
- Protects against rust and corrosion
- Helps reduce operating temperatures
- Maximum efficiency with wax-free cold-flow properties
- 100,000-mile normal service life in cars, SUVs and light trucks
- Flexible Easy-Pack for clean, fast installation
Severe-Duty Performance
SEVERE GEAR helps prevent thermal runaway — a phenomenon caused by a lubricant's inability to control friction and increased heat under high-stress conditions. By controlling thermal runaway, SEVERE GEAR inhibits rapid lubricant degradation and component damage.
Service life: 100,000 miles normal service or 50,000 miles severe service in cars, SUVs and light trucks.
