Purpose and Specifications

WOLF EXTENDTECH 80W90 LS GL 5 is a heavy-duty transmission oil designed for manual transmissions, hypoid differentials, and limited-slip axles in trucks, cars, and heavy equipment. This 20L drum delivers robust protection against shock loading, gear wear, and high torque, keeping gears smooth under heavy loads and high speeds.

Key specs include API GL5 rating for extreme pressure protection, MIL-L-2105 C/D compliance for military-grade durability, and 80W-90 viscosity that flows well in cold starts down to -15°C while staying thick at operating temps up to 120°C for reliable film strength.

• Protects against rust, corrosion, and foaming for cleaner, longer-lasting gears
• Smooths shifts and reduces noise in limited-slip systems
• Ideal for towing, hauling, and high-stress driving

When to Use / Replace?

Use in heavy-duty axles, final drives, and manual transmissions calling for GL-5 oils, especially older designs or limited-slip setups. Perfect for operations from cold winters to hot summers, handling low-speed/high-torque like off-road or heavy loads.

Replace every 50,000-100,000 km or 24-36 months under normal conditions; sooner (30,000 km) for severe duty like towing or dusty roads. Shelf life is 3-5 years unopened in cool, dry storage.

FAQ

Q: Is this safe for limited-slip differentials? A: Yes, the LS formula prevents chatter, noise, and vibration while providing absolute lubrication under shock loads.

Q: Can I use it in cold climates? A: Absolutely, the 80W rating ensures quick flow at low temps like -15°C, reducing startup wear.

Q: What vehicles fit this oil? A: Suits passenger cars, trucks, commercial vehicles, and classics with hypoid gears or manual transmissions needing GL-5.
