Purpose and Specifications

RAVENOL LS 90 GL-5 1L is a high-performance hypoid gear oil designed for differentials with limited slip (LSD) and manual transmissions. It delivers smooth power transfer, excellent wear protection, and reliable lubrication under heavy loads and high temperatures up to 150°C.

This synthetic-blend formula meets tough standards like API GL-5, MIL-L-2105 D, ZF TE-ML 05C, 12C, 16E, and 21C, ensuring compatibility with ZF axles, GM differentials, and hypoid gears in cars, trucks, and historic motorsport vehicles. Its SAE 90 viscosity stays thick at hot operating temps for lasting protection while flowing well down to -20°C for easy cold starts.

• Prevents chatter in limited slip differentials for quiet, smooth operation
• Resists rust, corrosion, and foaming to keep gears clean
• Extends gear life with superior extreme pressure additives

When to Use / Replace?

Use RAVENOL LS 90 GL-5 in limited slip differentials, rear axles, transfer cases, and manual transmissions calling for GL-5 LS oils. Ideal for high-stress driving like towing, racing, or off-road where gears face extreme pressure.

Replace every 50,000-80,000 km or 3-5 years under normal conditions, or sooner (30,000 km) for severe use like track days or heavy hauling. Shelf life is 5 years unopened in cool, dry storage.
