Purpose and Specifications

Castrol Transmax Universal LL 80W-90 is a premium semi-synthetic gear oil designed for heavy-duty manual transmissions and axles in trucks, buses, and commercial vehicles. This 20-liter canister provides smooth shifting, excellent wear protection, and reliable performance in tough conditions, meeting top specs like MAN 341 Z2, ZF TE-ML 02B/05A/12L/12M/16C, MB 235.0, and Scania STO 1:0/1:1G.

It flows easily in cold starts down to -30°C for quick protection and stays thick up to 150°C to shield gears under heavy loads and high heat. API GL-4/GL-5 ratings ensure extreme pressure protection, reducing metal-on-metal wear for longer transmission life.

When to Use / Replace?

Use this oil in approved commercial vehicles for everyday hauling, off-road work, or long-haul trucking. Ideal for synchronized and non-synchronized gearboxes needing versatile, high-performance lubrication.

• Replace every 60,000-100,000 km or 24-36 months under normal use; cut to 40,000 km in severe duty like towing or dusty roads.
• Check levels monthly; top up if low to prevent dry shifts.
• Shelf life: 5 years sealed in cool, dry storage.
