Purpose and Specifications

This LIQUI MOLY 4433 GL4+ 75W90 0.5L is a fully synthetic transmission oil designed for manual transmissions, transaxles, and final drives. It delivers smooth gear shifts, reduces noise and vibration, and provides excellent wear protection even under heavy loads. The 75W90 viscosity flows easily in cold starts down to -40°C and stays stable up to 200°C, ensuring reliable performance in extreme temperatures. Combining GL4 and GL5 properties, it meets specs like API GL4+, Ford ESD-M2C 175-A, VW 501 50, and ZF TE-ML 08, making it ideal for vehicles from Audi, VW, Ford, and more.

• Smooth, precise shifting without stiffness
• Reduces transmission noise and friction
• High thermal stability for towing or racing
• Long-lasting protection against wear and corrosion
• Compatible with seals and mixable with old mineral oil

When to Use / Replace?

Use this oil in high-load manual gearboxes experiencing stiff shifts, noise, or during routine maintenance. Replace every 60,000 to 100,000 km or 3-5 years, depending on driving conditions—sooner for severe use like off-road or heavy towing. Shelf life is 5 years unopened when stored cool and dry. Perfect for cold winters or hot summers, keeping gears lubricated from -40°C to over 100°C operating temps.

FAQ

Q: Is this safe for my synchros?
A: Yes, its GL4+ formula provides the right friction for smooth synchro engagement without the aggressiveness of full GL5 oils.

Q: Can I use it in hypoid differentials?
A: Absolutely, it offers high-pressure protection for hypoid gears in final drives under extreme loads.

Q: How much for a full change?
A: This 0.5L bottle tops off most transmissions; buy multiples for 1-2L fills common in passenger cars.
