Purpose and Specifications

WOLF EXTENDTECH 80W90 GL 5 5L is a tough mineral-based transmission oil built for heavy-duty gearboxes and hypoid axles. It handles high speeds, shock loads, and high torque at low speeds while keeping gears shifting smoothly and lasting longer.

Key practical benefits:

• Flows easily down to -33°C for reliable cold starts in winter.
• Stays stable up to 210°C flash point to protect during hot towing or hauling.
• Extreme pressure formula cuts wear, extending gear life up to 100,000 km or 3 years under normal use.
• Meets ZF TE-ML 05A/07A/12E/16B/16C/17B/19B, API GL-5, MIL-L-2105 C/D, MAN 342 M-1/M-2 specs for trucks, tractors, and passenger cars.

Shelf life: 5 years unopened in cool, dry storage.

When to Use / Replace?

Use in manual gearboxes, differentials, and transaxles on cars, trucks, and farm equipment facing tough conditions like off-road or heavy loads. Perfect for hypoid gears and spiral bevel setups.

Replace every 60,000-100,000 km or 2-3 years, or sooner if towing frequently, hearing gear noise, or after water exposure. Check level monthly.

FAQ

Is this oil good for limited-slip differentials?
This standard GL-5 version excels in standard hypoid axles; for limited-slip, choose the LS variant.

Can I use it in my ZF transmission?
Yes, it meets multiple ZF TE-ML specs for smooth operation in ZF gearboxes.

What if my temps drop below freezing?
Protects down to -33°C pour point and flows at -26°C, preventing cold-start damage.
