SYNGEAR SS

PREMIUM SEMI-SYNTHETIC PROTECTION FOR HEAVY-DUTY AXLES.

Close

Syngear SS is a high-performance, semi-synthetic gear lubricant designed for use in passenger car and truck axles operating under severe conditions. By combining the shear stability of synthetic base stocks with high-quality conventional oils, it provides an enhanced level of thermal stability and load-carrying capacity. It is the ideal choice for fleets requiring a step up in protection for high-load differentials without moving to a full-synthetic cost structure.

PRODUCT RESOURCES 

PERFORMANCE

  • Blended to provide superior low-temperature fluidity for immediate start-up protection.

  • Maintains stable viscosity under high-heat operation to ensure consistent gear shielding.

  • Optimized friction characteristics for quiet, vibration-free operation in modern drivetrains.

PROTECTION

  • Semi-synthetic film strength prevents metal-to-metal contact during high-torque events.

  • Advanced extreme-pressure additives protect against gear scuffing and surface pitting.

  • Superior resistance to rust and corrosion, even in high-moisture coastal environments.

UPTIME

  • Improved thermal stability resists the formation of sludge and carbon deposits.

  • Protects critical seals and bearings from heat-related failure, reducing leak-related repairs.

  • Extends the life of the lubricant and the hardware compared to standard conventional oils.

FEATURES & BENEFITS

  • Semi-synthetic blend provides a durable barrier against gear tooth pitting.

  • Enhanced low-temperature flow compared to standard conventional gear oils.

  • Superior thermal stability resists the formation of high-heat carbon deposits.

  • Protects critical axle seals from hardening to prevent long-term leaks.

  • Provides excellent load-carrying capacity for frequently loaded service trucks.

APPLICATIONS

Used in manual transmissions and differentials for trucks, buses, and off-road equipment operating under heavy or frequent loads.

MAMMOTH TECHNICAL TIP:

Syngear SS is the perfect upgrade for fleets seeing high oil temperatures. It offers better heat dissipation than conventional oil, saving seals from hardening and leaking.
