Liqui Moly Fully Synthetic Hypoid Gear Oil (GL4/5) 75W-90 - 1L

Liqui Moly Fully Synthetic Hypoid Gear Oil (GL4/5) 75W-90 - 1L

The Universal Performance Standard for German and European Drivetrains

Give your vehicle the precision protection it deserves with Liqui Moly SKU: 22090. This fully synthetic gear oil is specifically formulated to bridge the gap between high-pressure protection and synchronizer compatibility. Its unique GL4/GL5 dual-rating makes it incredibly versatile, providing the Extreme Pressure (EP) protection needed for rear-axle hypoid gears while remaining gentle enough for the yellow metals (brass/bronze) found in manual gearboxes. Whether you’re maintaining a high-mileage daily driver or a tuned track machine, this fluid offers superior thermal stability and aging resistance for extended service intervals.

What’s Included in the Box:

- (1) 1 Liter (1.05 Quart) Bottle: Features a built-in extendable pour spout for easy, mess-free filling in tight spaces.

The Liqui Moly Advantage

- Dual GL4/GL5 Specification: A "universal" lubricant that simplifies maintenance by being safe for both manual gearboxes and high-stress differentials.

- Superior Cold Flow: Ensures immediate lubrication and reduces "notchy" shifting during cold starts, maintaining a buttery feel even in sub-zero temperatures.

- High-Pressure Stability: Forms a robust protective film that prevents metal-to-metal contact and gear pitting under extreme loads and high torque.

- Noise & Vibration Reduction: High-quality synthetic base stocks and additives help dampen drivetrain hum and mechanical vibration.

- Extended Service Life: Exceptional oxidation resistance keeps the fluid from thinning or breaking down, ensuring consistent protection over tens of thousands of miles.

Precision Tip: Because this is a TDL (Total Drive Line) oil, it is ideal for vehicles like the BMW 3-Series or VW Golf where the owner wants one high-quality fluid for both the transmission and the differential. However, if your vehicle is equipped with a plate-type Limited Slip Differential (LSD), you may need to add a friction modifier or use Liqui Moly’s dedicated "LS" fluid to prevent differential chatter during tight turns.
