Liqui Moly 20042 Gear Oil - Center, Front Differential, Rear or Rear Differential

Liqui Moly 20042 Gear Oil for High-Load Differentials

Liqui Moly Fully Synthetic Hypoid Gear Oil (GL5) LS SAE 75W-140 is formulated for rear differentials and final drives that see heavy load, high heat, and demanding driving conditions. It is a strong choice for limited-slip applications and performance-oriented drivetrains where stable viscosity and wear protection matter.

Key Features

• Fully synthetic hypoid gear oil with GL-5 performance
• LS formulation for wet clutch-based limited-slip differentials
• Stable viscosity for consistent protection under extreme operating conditions
• Multi-functional EP additive package for wear control
• Suitable for hi-load transmissions and differentials in race and track use
• 1 liter plastic can

Product Details

This Liqui Moly gear oil is built for final drives and differentials that need dependable lubrication under stress. The SAE 75W-140 viscosity grade supports high-temperature operation, while the limited-slip additive package helps maintain proper differential function where wet clutch-based LSD hardware is used. Part number 20042 is listed for a wide range of rear differential and front differential applications across performance cars, SUVs, and trucks, including Mercedes-Benz AMG models, Jeep Wrangler, Toyota GR Corolla, and Ford Super Duty platforms.

Liqui Moly’s Fully Synthetic Hypoid Gear Oil (GL5) LS SAE 75W-140 is also referenced for vehicles such as Cadillac CT4 and CT5 rear differentials, Dodge Durango rear differential service, and Subaru WRX and BRZ rear differential applications. If you are searching for a fitment-based solution such as “75W-140 rear differential oil for Jeep Wrangler” or “GL-5 limited slip gear oil for Mercedes-Benz AMG rear differential,” this product matches those service needs where the vehicle listing calls for this specification.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Gear wear in high-load differentials
• Heat-related viscosity breakdown during aggressive driving
• Noise or chatter in limited-slip differential service when the correct LS fluid is required
• Lubrication demands in towing, track use, and performance driving
• Rear differential service on vehicles calling for SAE 75W-140 GL-5 gear oil

Installation Notes and Tips

Verify the vehicle service specification before filling, especially on applications that call for limited-slip gear oil, front differential service, or year-round use. Drain the old fluid completely, inspect the housing for contamination, and refill to the manufacturer’s specified level. Use the exact viscosity and specification listed for the vehicle, since some fitments in the catalog note temperature range or differential type.

Quality Assurance

Liqui Moly develops this gear oil to meet the high requirements of well-known vehicle manufacturers and to provide dependable protection in demanding drivetrain service. Part number 20042 is a technical lubricant choice for drivers and technicians who need GL-5 hypoid gear oil with LS capability.
