SEVERE GEAR 75W-110 Synthetic EP Gear Lube
AMSOIL SEVERE GEAR 75W-110 provides a heavier viscosity for applications requiring additional film strength under extreme loads. It maintains its viscosity for long-lasting protection against metal-to-metal contact and forms an iron-sulfide barrier coating on gear surfaces.
Key Benefits
- Advanced protection against wear, pitting and scoring
- Controls thermal runaway under high-stress conditions
- Heavier viscosity for additional film strength under extreme loads
- 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. It resists breakdown from high heat, preventing acid and carbon/varnish formation.
Service life: 100,000 miles normal service or 50,000 miles severe service in cars, SUVs and light trucks.

Frequently Asked Questions
Use 75W-110 when your application requires a heavier viscosity for additional film strength under extreme loads, or when the OEM specifies a 75W-110 grade. Check your owner's manual for the correct viscosity specification.
Yes. AMSOIL SEVERE GEAR is compatible with most limited-slip differentials. For applications that require additional limited-slip friction modifier, add AMSOIL Slip Lock.

I've been using Amsoil Severe Gear for years in all my equipment including my previous HTM 850 HP Boat. I used 75W-110 in my Bravo 1 OD and never had a problem. Sure you can find various brands of synthetic oil going to chain stores or auto parts stores but none offer the proven protection of Amsoil products IMHO.
