Mercedes-Benz G-Class, W465 (EU)

Automatic transmission fluid capacity & service interval

Mercedes-Benz G-Class, W465 (EU) uses automatic transmission fluid with a capacity of 10-11 liters. The service interval is 120000 km. The data covers 2 configurations.

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

Additional Notes

  • Both the G 450 d (465.310) and G 500 (465.210) share an automatic transmission fluid dry fill capacity of 10-11 liters. A dry fill figure represents the total fluid volume required when filling a completely drained or rebuilt transmission, as opposed to a partial drain-and-fill service, which typically displaces a smaller portion of the total fluid volume.
  • The 10-11 liter range listed for the dry fill capacity reflects a tolerance band rather than a fixed value, accounting for minor variation during the fill procedure or differences in how completely the transmission has been drained before refilling.
  • Under normal use conditions, the Mercedes-Benz G-Class W465 (EU) automatic transmission fluid change interval is set at 120,000 km for both the G 450 d and G 500 variants. Normal use conditions generally refer to standard on-road driving without the sustained high-load or high-temperature cycles that would otherwise qualify as severe service.
  • The 120,000 km change interval is consistent across both the diesel G 450 d and the petrol G 500, despite the two variants using different engine types. Diesel powertrains can introduce combustion byproducts into drivetrain fluids at different rates than petrol engines, making the shared interval a notable point of alignment between the two configurations.
