Differential fluid capacity & service interval

Lexus RZ (EU) differential fluid capacity is 3,1 liters. Service intervals include checking every 45000 km/36 months or 60000 km/48 months, and changing every 90000 km/72 months. The data covers 2 configurations.

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

Additional Notes

  • The Lexus RZ 450e AWD rear electric drive differential carries a service fill capacity of 3.1 liters, a figure that reflects a partial drain-and-refill rather than a complete fluid evacuation, which would typically yield a higher total system volume.
  • Under normal use conditions, the rear differential fluid on the RZ 450e AWD is subject to a check interval of 48 months or 60,000 km, with no separate change interval specified for that use condition.
  • Under severe use conditions, the same 3.1-liter service fill capacity applies, but the maintenance schedule splits into two distinct actions: a fluid check at 36 months or 45,000 km, followed by a fluid change at 72 months or 90,000 km.
  • The check interval under severe use, at 36 months or 45,000 km, arrives earlier than the 48-month or 60,000 km check interval assigned to normal use, reflecting the additional stress placed on the fluid under more demanding operating conditions.
  • The severe-use change interval of 72 months or 90,000 km establishes a hard replacement point that has no equivalent in the normal-use schedule, where only a check interval is listed.
