Purpose and Specifications

LIQUI MOLY 4434 GL4+ 75W90 1L is a fully synthetic high-performance gear oil designed for manual transmissions, transaxles, and axle drives. Its 75W-90 viscosity flows smoothly in cold starts down to -40°C and stays thick under extreme heat up to 150°C, ensuring reliable protection in all weather conditions.

This oil meets API GL4 and GL5 standards, plus approvals like VW 501 50 (G50), Ford ESD-M2C 175-A, and ZF TE-ML 08, making it ideal for vehicles from Audi, VW, Ford, and more. Key benefits include reduced transmission noise, easier gear shifts, outstanding wear resistance, excellent corrosion protection, and long-lasting performance that prevents breakdowns even under high loads.

• Reduces gearshift effort for smoother driving
• Quiets noisy transmissions
• Protects seals and components from wear
• Handles high-pressure conditions without thinning out

When to Use / Replace?

Use this oil in high-load manual transmissions requiring GL4+ or GL5 specs, especially in modern transaxles and hypoid gears. Perfect for daily drivers, performance cars, or heavy towing. Replace every 60,000 km or 3 years under normal conditions, or sooner at 30,000 km if towing frequently or in severe climates. Shelf life is 5 years unopened.

Frequently Asked Questions

Is this safe for my VW or Audi manual transmission? Yes, it meets VW 501 50 (G50) and is recommended for VW Group vehicles, providing exact friction for smooth shifts without damaging synchros.

Can I mix it with my old gear oil? Yes, it's miscible with mineral-based residues, but for best results, drain fully and refill with fresh oil.

What if my transmission runs hot? Its wide viscosity range offers superior protection up to 150°C, reducing wear during heavy use or track days.
