Mercedes-Benz G-Class, W463B (USA / CAN)

Differential fluid capacity & service interval

Mercedes-Benz G-Class, W463B (USA / CAN) uses differential fluid with a capacity range of 1,4 to 1,8 liters. Service intervals occur every 50000 miles or 48 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The front differential on both the G 550 (463.261) and G 63 AMG (463.277) holds 1.4 liters of fluid, while the rear differential on each variant holds 1.8 liters, reflecting the larger housing and gear set typical of a rear axle unit carrying primary drive load.
  • The 0.4-liter difference between front and rear differential capacities is consistent across both the G 550 and G 63 AMG configurations for 2019-2024, indicating a shared axle architecture between the two variants despite their differing powertrains.
  • All four differential positions across both variants share an identical service interval of 50,000 miles or 48 months under normal use conditions, meaning whichever threshold arrives first would trigger a fluid change.
  • The 48-month time limit paired with the 50,000-mile mileage threshold means lower-mileage vehicles driven infrequently are still subject to a fluid change within four years under the normal use condition specified for all listed configurations.
  • The Mercedes-Benz G-Class W463B carries separate front and rear differential fluid capacities rather than a combined axle fill figure, so service requires two distinct fill operations with differing volumes at each axle.
