Purpose and Specifications

RAVENOL SGO 80W-140 4L is a full synthetic transmission oil designed for heavily loaded hypoid gearboxes, axles, differentials, and manual transmissions in trucks, heavy machinery, and high-performance vehicles. It delivers a tough, pressure-resistant film that shields gears from wear even under extreme loads and temperatures from -30°C to +150°C.

This oil meets top specs like API GL-5, Mack GO-J, ZF TE-ML 05A/07A/12E/16C/16D/21A, and SCANIA STO 1:0, ensuring smooth shifting, no foaming, and rust protection. The 80W-140 viscosity flows easily in cold starts yet stays thick for hot towing or off-road abuse, extending gear life in demanding conditions.

When to Use / Replace?

Use RAVENOL SGO 80W-140 in hypoid axles, transfer cases, and heavy-duty manuals where manufacturers specify GL-5 oils. Perfect for long-haul trucks, construction equipment, or motorsport differentials handling high torque.

• Replace every 100,000-500,000 km (or 60,000-300,000 miles) in on-road long-haul apps, or sooner (every 50,000 km) for off-highway, towing, or city stop-go driving.
• Check levels monthly; change if fluid darkens or smells burnt.
• Shelf life: 5 years unopened in cool, dry storage.
