Finol Gear Oil LS 80W-90 20L – Limited-Slip Differential Gear Oil | DGEA09

Finol Gear Oil LS 80W-90 is a mineral-based extreme pressure gear lubricant specially formulated for limited-slip differentials and compatible driveline systems. Designed for applications requiring API GL-5 LS performance, it provides protection for heavily loaded gears while supporting smooth operation of limited-slip differential clutch assemblies.

With an SAE 80W-90 viscosity grade, this gear oil is suitable for demanding axle and differential applications across automotive, commercial vehicle, agricultural and construction equipment. Its specialised friction characteristics help reduce differential chatter and support consistent clutch performance when the lubricant is used in the correct application.

Supplied in a 20-litre container, Finol Gear Oil LS 80W-90 is a practical option for workshops, fleet operators and agricultural or construction machinery maintenance.

Key Features and Benefits

• API GL-5 LS performance: Intended for limited-slip gear systems requiring this performance level.

• Extreme pressure protection: Helps protect heavily loaded gears against wear.

• Friction-modifying properties: Support smooth operation of compatible differential clutch packs.

• Helps reduce chatter: Formulated to help minimise noise and judder associated with limited-slip differential operation.

• High-temperature stability: Supports reliable lubrication under demanding operating conditions.

• Component protection: Helps protect gears and differential components during service.

• Versatile applications: Suitable for compatible automotive, agricultural and off-highway equipment.

Applications

Finol Gear Oil LS 80W-90 is designed for driveline systems requiring a limited-slip API GL-5 lubricant, including:

• Limited-slip differentials.

• Differential and final-drive systems.

• Agricultural tractors and machinery.

• Construction and off-highway equipment.

• Cars and vans with compatible limited-slip differentials.

• Trucks, buses and commercial vehicles where specified.

• Heavily loaded axle and gear systems requiring the appropriate LS lubricant.

Important compatibility note: Limited-slip differentials can require specific friction characteristics. Do not assume this oil is suitable for every axle or differential. Check the equipment manufacturer's handbook for the required viscosity, LS performance level and any additional manufacturer-specific requirements.
