Liqui Moly Gear Oil

Liqui Moly Gear Oil: German Engineering for Every Transmission

Liqui Moly has built a global reputation on precision lubrication, and their gear oil lineup is one of the clearest expressions of that philosophy. Developed and manufactured in Germany, these transmission fluids are engineered to meet — and often exceed — the stringent requirements set by the world's most demanding automakers, from BMW and Mercedes-Benz to Volkswagen, Volvo, and ZF.

A Range Built for Real-World Demands

What sets Liqui Moly apart in the gear oil category is the sheer breadth of coverage combined with application-specific chemistry. Rather than offering a handful of catch-all products, Liqui Moly engineers distinct formulations for each transmission type:

• High Performance Gear Oil GL4+ (75W-90): A fully synthetic manual transmission fluid delivering outstanding wear protection. It offers high shear stability combined with correct friction behavior, and its outstanding resistance to viscosity breakdown provides superior shift performance in all operating conditions.
• High Performance Gear Oil GL3+ (75W-80): Based on synthetic technology with extremely high performance reserves, it produces precise friction characteristics, offers outstanding resistance to aging, and exceeds the high test requirements of well-known vehicle manufacturers.
• Fully Synthetic Hypoid Gear Oil GL4/5 (75W-90): Ideally suited for high performance applications even under extreme loads and operating conditions. It ensures maximum wear protection and promotes precise functionality over a wide temperature range, enabling longer oil change intervals.
• Fully Synthetic Hypoid Gear Oil GL5 LS (75W-140): Developed for use in final drives with or without wet clutch-based differentials (Limited Slip), with stable viscosity and multifunctional EP additives that guarantee maximum wear protection even under extreme operating conditions.
• Dual Clutch Gear Oil 8100: A fully synthetic gear oil developed specifically to meet a variety of OE manufacturers' Dual Clutch Transmission (DCT) specifications, with latest additive technology ensuring superior clutch control, best shift performance, and outstanding wear protection.

The MoS2 Advantage

A distinguishing thread running through much of Liqui Moly's gear oil philosophy is the use of molybdenum disulfide (MoS2) chemistry. Their Gear-Oil Additive contains highly concentrated MoS2 to reduce wear in manual and differential transmissions, axle drives, and mechanical steering systems, while MoS2 reduces temperature peaks and ensures quieter running. This same friction-reduction science informs the additive packages across their broader gear oil range.

OEM-Level Approvals You Can Trust

Liqui Moly gear oils carry a comprehensive roster of OEM approvals. Products in their lineup meet API GL4/GL5/MT-1 standards and carry approvals from BMW, Mercedes-Benz (MB 235.8/235.11), MIL-PRF 2105 E, SAE J 2360, Volvo 97312, and multiple ZF TE-ML specifications. This level of OEM certification means technicians and enthusiasts can select a Liqui Moly gear oil with confidence that it meets the exact tolerances their drivetrain was designed for.

Why Gear Oil Quality Matters

Gear oils are special lubricants used exclusively in vehicle transmissions, playing a decisive role in durability and trouble-free functioning. The gear oil reduces friction between moving parts of the transmission, minimizing wear and extending the service life of components. Choosing a precision-formulated product like those in the Liqui Moly lineup is one of the most cost-effective ways to protect a transmission investment over the long haul.

Whether you're maintaining a daily driver, servicing a performance vehicle with a ZF transaxle, or rebuilding a classic with a manual gearbox, Liqui Moly's gear oil range offers a purpose-built solution.
