Purpose and Specifications

LIQUI MOLY Hypoid Gear Oil (GL4/5) TDL SAE 75W-90 is a fully synthetic transmission fluid designed for manual, auxiliary, and differential transmissions in commercial and passenger vehicles. This universal oil meets API GL4, GL5, and MT-1 performance standards, making it compatible with a wide range of transmission types.

Key Performance Benefits:

• Reduces frictional losses and improves fuel economy
• Ensures smooth gear engagement and optimal shifting performance
• Provides outstanding viscosity stability across temperature ranges
• Increases overall lubricating effect for extended component life
• Protects against wear and corrosion in high-pressure environments

Viscosity Grade: SAE 75W-90 means the oil flows easily in cold conditions (75W rating) while maintaining protective thickness at high operating temperatures (90 rating). This makes it suitable for year-round use in most climates.

When to Use / Replace?

Replace transmission fluid every 80,000 to 160,000 kilometers or every 2 to 4 years, depending on your vehicle manufacturer's recommendations and driving conditions. Check your owner's manual for specific intervals. This oil is ideal for vehicles requiring GL4/GL5 specifications, including ZF, DAF, Eaton, MAN, and Scania transmissions.

Operating Temperature Range: Suitable for use in temperatures from approximately -30°C to +90°C, making it effective in both cold winter starts and hot summer driving.

Container Size: 500 ml bottle for convenient topping up or small transmission services.

Frequently Asked Questions

Q: Can I use this oil in both manual and automatic transmissions?
A: This product is formulated for manual, auxiliary, and differential transmissions. Always verify your vehicle's transmission type and manufacturer specifications before use, as automatic transmissions often require different fluid formulations.

Q: How do I know if my transmission needs this oil?
A: Check your vehicle's owner's manual for the required API specification (GL4, GL5, or MT-1) and viscosity grade (75W-90). If your manual lists any of the approved manufacturers (ZF TE-ML 02B, 08, 16B, 17B, 19B, DAF, Eaton, MAN, or Scania), this oil is compatible.

Q: What makes synthetic oil better than conventional?
A: Fully synthetic oils like this one provide superior viscosity stability, better protection at extreme temperatures, longer service intervals, and improved fuel economy compared to conventional mineral oils. They also resist breakdown and aging better over time.
