Purpose and Specifications

LIQUI MOLY 1415 Fully Synthetic Gear Oil (GL5) SAE 75W-90 is a premium full synthetic transmission oil designed for manual transmissions, differentials, and axle drives. This 20-liter drum delivers maximum wear protection and smooth gear shifting by reducing friction between moving parts, even under extreme loads and temperatures from -40°C cold starts to over 150°C operating heat.

It ensures reliable lubrication that quiets noisy gears, prevents overheating, and extends transmission life with outstanding aging resistance for longer change intervals up to 100,000 km or 5 years, depending on vehicle specs.

When to Use / Replace?

• Use in high-load manual transmissions, hypoid gears, and differentials requiring API GL5 specs for vehicles like Audi, VW, Ford, and many others.
• Replace every 60,000-100,000 km or 3-5 years to maintain smooth operation and avoid costly repairs from wear or contamination.
• Ideal for harsh conditions like towing, racing, or extreme weather where standard oils break down quickly.
