Purpose and Specifications

RAVENOL SGO 80W-140 1L is a full synthetic gear oil designed for heavy-duty hypoid gearboxes, axles, transfer cases, and manual transmissions in cars, trucks, and agricultural machinery. It delivers a tough lubricating film that protects gears from wear even under extreme loads and high-pressure conditions, staying effective from cold starts at -12°C up to hot operating temps over 100°C.

Key specs include API GL-5 and MT-1 ratings for superior extreme pressure protection, plus approvals like Mack GO-J, MIL-L-2105D, SAE J2360, SCANIA STO 1:0, and multiple ZF TE-ML standards (05A, 07A, 12E, 16C, 16D, 21A). This means smooth shifting, rust prevention, and long-lasting performance without foaming or corrosion.

• Flows easily in cold weather for quick protection on startup
• Maintains thickness at high temps to prevent metal-on-metal contact
• Reduces wear in hypoid gears under severe stress like towing or off-road use

When to Use / Replace?

Use RAVENOL SGO 80W-140 in highly loaded hypoid gearboxes where manufacturers specify this viscosity and GL-5 specs. Ideal for passenger cars, trucks, and farm equipment facing heavy loads or extreme conditions.

Replace every 100,000-150,000 km or 3-5 years in standard use, or up to 800,000 km in approved Mack long-haul applications with proper filters. Check levels monthly and top up if low. Shelf life is 5 years unopened when stored cool and dry.

FAQ

Is this oil suitable for my truck's differential? Yes, its Mack GO-J and ZF approvals make it perfect for heavy-duty axles and differentials under high loads.

Can I mix it with other gear oils? Best to fully drain old oil first for maximum protection, but it's compatible with most GL-5 oils without flushing.

What temps does it handle? Excels from -12°C cold starts to over 100°C hot running, keeping gears protected year-round.
