Purpose and Specifications

Keep your truck, bus, or heavy-duty vehicle's manual transmission and differentials running smooth with Mobilube 1 SHC 75W-90 transmission oil (part 142803). This full synthetic gear oil excels in extreme conditions, flowing easily at cold starts down to -40°C for quick shifts and staying thick at high temps up to 150°C to prevent wear.

Approved for major brands like Scania STO 2:0 A FS, MAN 341 Typ Z2/E3/GA1, ZF TE-ML 02B/05A/07A/08/12L/12N/16F/17B/19C/21A, Mack GO-J, and more, it cuts friction for better fuel economy and lasts up to 500,000 km or 5 years in normal fleet use before needing replacement.

• 1-liter bottle perfect for precise top-ups or full drains.
• Protects gears from rust, sludge, and scoring in tough off-road or towing jobs.

When to Use / Replace?

Use this premium synthetic oil in manual gearboxes and axles on commercial vehicles like Scania, MAN, ZF-equipped trucks, or even cars such as VW Golf, Audi A4, Ford Fiesta needing GL-4/GL-5 specs. Ideal for high-load hauling where standard oils break down fast.

Replace every 200,000-500,000 km (or 2-5 years) based on your service manual, or sooner if shifting gets noisy, fluid darkens, or you notice metal shavings. Drain and refill during routine maintenance to extend gear life by 2-3x over mineral oils.
