- ENGINEERED FOR MAXIMUM GEAR PROTECTION – STARFIRE 75W-140 synthetic gear oil is built to endure extreme heat, pressure, and torque in heavy-duty differentials, axles, and transmissions for lasting reliability.
- EXTREME-PRESSURE PERFORMANCE YOU CAN TRUST – Enhanced with high-performance anti-wear agents, this gear oil reduces metal contact and prevents scoring in hypoid gears and high-load commercial fleet systems.
- LONG-TERM RUST & CORROSION DEFENSE – Advanced oxidation and rust inhibitors form a protective barrier on metal surfaces, guarding against moisture damage in severe work environments and wet conditions.
- THERMAL & VISCOSITY STABILITY UNDER LOAD – Maintains stable viscosity at high temperatures and resists foaming for smooth, quiet operation—supporting optimal power transfer under heavy-duty workloads.
- MEETS KEY INDUSTRY & OEM SPECIFICATIONS – Exceeds GL-5 and MT-1 specs and is compatible with MIL-PRF-2105E/D, Mack GO-J/GO-H, PG-2 Limited Slip, and Volvo i-Shift gear systems used in demanding applications.
