80W-90 Gear Oil (High Performance GL-5 and LS)

Greyhound 80W-90 Gear Oil range includes high-performance extreme pressure (EP) lubricants formulated from premium mineral base oils and advanced additive technology. Available in both GL-5 and GL-5 LS (Limited Slip) formulations, these oils provide excellent thermal stability, oxidation resistance, and protection against wear, shock loading, and deposit formation, helping to extend both lubricant and component life under demanding operating conditions.

The oil forms a durable protective film, making it suitable for use in manual transmissions, differentials, final drives, and other heavy-duty applications across passenger vehicles, commercial fleets, and construction equipment.

• GL-4 – Moderate EP performance for certain manual gearboxes and synchronised transmissions where compatibility with yellow metals (such as brass/bronze components) is required.
• GL-5 – High EP performance for hypoid gears, axles, and standard differentials operating under heavy load and shock conditions. Not typically recommended for applications requiring yellow metal compatibility unless specified.
• GL-5 LS (Limited Slip) – Includes friction modifiers to prevent clutch chatter and ensure smooth, controlled operation in limited-slip differentials.

Use GL-5 for standard applications requiring maximum load protection, GL-5 LS where limited-slip performance is specified, and GL-4 only where required by the equipment manufacturer.
