Purpose and Specifications

LIQUI MOLY 1414 is a fully synthetic gear oil (SAE 75W-90, API GL5) designed for high-load manual transmissions, auxiliary drives, transaxle systems, and hypoid axle gears without limited-slip differentials. This 1-liter boxed oil delivers maximum wear protection and smooth gear shifting by maintaining perfect lubrication across extreme temperatures from -40°C to over 150°C.

It excels in harsh conditions like towing, off-road driving, or heavy loads, reducing noise, vibration, and gearshift effort while preventing corrosion and keeping gears clean. Outstanding aging resistance means it stays effective longer than conventional oils.

When to Use / Replace?

• Use it in: High-performance manual gearboxes, differentials, and transaxles per manufacturer specs (check API GL5, MIL-L 2105 C/D compatibility).
• Replace every 60,000-100,000 km or 3-5 years under normal driving; sooner (30,000-50,000 km) for severe use like racing, towing, or extreme temps.
• Shelf life: Up to 5 years unopened in cool, dry storage.
