Overview
This genuine OEM ZF 0671.090.533 GEARBOX OIL is a high-viscosity lubricant specifically engineered for the internal gear train and shaft assemblies within ZF WG100, WG130, and WG131 transmissions. It serves as the primary hydraulic and lubricating fluid, reducing friction between meshing gears and dissipating heat from the differential and bearing surfaces. The SKU 0671.090.533 is formulated to meet ZF’s exacting shear stability and thermal resistance standards, ensuring consistent film strength under heavy load. This oil circulates through the gearbox housing, directly contacting components like the 2093109003: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to prevent metal-on-metal contact.
Symptoms of Failure
- Gear Slipping Under Load: Worn or degraded oil loses its film strength, causing the 2093209096: DIFFERENTIAL to momentarily lose torque transfer during acceleration.
- Persistent Oil Leaks from Seals: Thermal breakdown of the 0671.090.533 oil increases internal pressure, forcing fluid past shaft seals and leaving puddles under the transmission housing.
- Whining or Grinding Noise: Contaminated or low-viscosity oil fails to cushion the 2093309073: DIFF.HOUSING, producing audible metallic chatter during gear engagement.
- Overheating Transmission: Oxidized oil cannot effectively transfer heat, leading to elevated operating temperatures and potential damage to the gear train.

Frequently Asked Questions
Q: Can I use this oil in a ZF WG180 transmission?
A: Yes, the 0671.090.533 oil is compatible with WG180 models that require SAE 80W-90 viscosity, but always cross-reference your transmission’s original fill specification.
Q: How often should I replace the gearbox oil?
A: ZF recommends changing the 0671.090.533 oil every 1,000 operating hours or 12 months, whichever comes first, to maintain peak lubrication of the differential and bearings.
Q: What happens if I mix this oil with a different viscosity?
A: Mixing viscosities can degrade film strength and cause premature wear on the taper roller bearing and differential gears. Always use the genuine 0671.090.533 fluid.
