Purpose and Specifications

RAVENOL LS 90 GL-5 4L is a high-performance mineral-based transmission oil designed for hypoid gears, differentials, and manual transmissions in vehicles and heavy machinery. It meets tough standards like API GL-5, MIL-L-2105 D, ZF TE-ML 05C, 12C, 16E, and 21C, ensuring reliable protection under extreme loads.

This oil delivers excellent wear protection with EP additives that form a tough lubricating film, even in high-stress hypoid gears and limited-slip differentials. It handles operating temperatures from -20°C to 150°C without breaking down, prevents corrosion, and offers superior limited-slip performance to avoid chatter and slippage. The 90 viscosity provides steady flow in cold starts and thick protection when hot, extending gear life in trucks, cars, and off-road equipment.

• Prolongs oil change intervals up to 100,000 km or 24 months per manufacturer guidelines
• Shelf life of 5 years when stored cool and dry
• 4-liter container perfect for complete transmission or differential fills

When to Use / Replace?

Use RAVENOL LS 90 GL-5 in manual transmissions, axle drives, transfer cases, and locking differentials calling for GL-5 specs, especially in high-load conditions like towing, off-roading, or commercial vehicles. Ideal when switching from seasonal oils—no flushing needed, mixes well with similar brands.

Replace every 60,000-100,000 km or 12-24 months, or sooner if you notice gear noise, slipping, or leaks. Check levels monthly for heavy use; change immediately after water contamination or overheating beyond 150°C.
