Purpose and Specifications

WOLF VITALTECH 75W90 GL 5 1L is a full synthetic transmission oil designed for smooth, reliable performance in gearboxes, transfer cases, and differentials of trucks, 4x4 vehicles, and heavy-duty applications. Its special formula delivers very smooth gear shifting without vibration, even in synchronized gearboxes and heavily loaded differentials under extreme conditions.

This budget-class oil excels in practical benefits: superior anti-wear protection shields critical gears and bearings from damage during high-speed shock loads or low-speed high-torque work, while excellent thermal stability keeps it performing from -40°C cold starts up to 200°C operating temps. Selected additives reduce oil breakdown for longer gear life and extended drain intervals up to 100,000 km or 24 months in normal use.

• Smooth shifting: No clunking or vibration in syncro boxes
• Tough protection: Handles heavy loads and extreme temps
• Long life: Stays effective longer, cutting maintenance costs
• Wide approvals: Meets ZF TE-ML 02B/05B/07A/08/12B/12L/12N/16F/17B/19C/21B, MAN 341 Z2/M342 M3, SCANIA STO 1:0, API GL4/GL5/MT-1, MIL-PRF-2105E

When to Use / Replace?

Use this oil in mechanical transmissions of trucks, 4WDs, and off-road vehicles needing GL-5 protection for hypoid gears. Ideal for daily drivers facing towing, hauling, or harsh weather. Replace every 80,000-120,000 km or 18-24 months, or sooner if operating in dusty/mining conditions or temps over 150°C regularly. Shelf life is 5 years unopened when stored cool and dry.

FAQ

Q: Will it harm my synchro gearbox?
A: No, its excellent frictional properties ensure smooth shifting without damage to synchros, approved for ZF specs.

Q: What temps does it handle?
A: Flows easily at -40°C for cold starts and stays thick up to 200°C for hot towing or off-roading.

Q: How often change for trucks?
A: Every 100,000 km or 24 months under normal loads; check level monthly for heavy use.
