Purpose and Specifications

LIQUI MOLY 3072 Transmission Oil SAE 75W-140 is a high-performance gear oil designed for manual transmissions, differentials, and hypoid axles in passenger cars and trucks. This fully synthetic formula delivers a tough lubricating film that cuts wear by up to 35% during high loads, ensures smooth shifting even in cold starts down to -40°C, and stays thick under extreme heat up to 150°C.

It provides top corrosion protection, reduces noise for quieter operation, and supports extended drain intervals up to 100,000 km or 5 years, depending on vehicle specs. Perfect for high-load hypoid gears in BMWs, Japanese vehicles, and transaxle systems.

When to Use / Replace?

• Change every 60,000-100,000 km or 4-5 years for everyday driving to prevent sludge buildup and maintain peak performance.
• Replace sooner if towing heavy loads, racing, or driving in harsh conditions like extreme temps or dusty roads.
• Ideal for vehicles with limited-slip differentials; check fluid level and color during oil changes - dark or burnt smell means immediate service.
