Purpose and Specifications

RAVENOL MZG 80W-90 GL-4 is a premium mineral gear oil designed for manual transmissions, differentials, and steering gears in passenger cars, trucks, agricultural machinery, and classic vehicles. This 4-liter pack delivers tough wear protection and stays reliable from cold starts down to -20°C to high-heat operation up to 150°C, ensuring smooth shifting and long gear life under heavy loads.

It meets key specs like API GL-4, ZF TE-ML 02B/16A/17A/19A, MB 235.1/235.14, and MAN 341 E1/Z1, making it perfect for vehicles needing EP (extreme pressure) transmission oil without damaging yellow metals like brass synchros.

• Builds strong, clinging oil films that resist pressure and prevent metal-on-metal wear
• Excels in oxidation stability to avoid sludge buildup over time
• Flows easily in cold weather for quick protection on startup
• Prevents foaming and releases air fast for consistent lubrication
• Safe on seals and metals, no corrosion or leaks

When to Use / Replace?

Use RAVENOL MZG 80W-90 in any manual gearbox, axle, or steering system matching its approvals - ideal for older cars, farm equipment, and trucks in mixed climates. Replace every 40,000-60,000 km or 2-3 years, or sooner if towing heavy loads, off-roading, or driving in extreme temps. Shelf life is 5 years unopened when stored cool and dry.
