Toyota RAV4, XA50 (USA / CAN)
Differential fluid capacity & service interval
Toyota RAV4, XA50 (USA / CAN) differential fluid capacity ranges from 0,5 to 1,7 liters. Service intervals include checks at 15000 miles/18 months or 30000 miles/36 months, and changes at 30000 miles/36 months or 60000 miles/72 months. The data covers 12 configurations.

Additional Notes
- The Toyota RAV4 XA50 2.5 4WD rear differential holds 0.5 to 0.53 liter of fluid. A capacity in this range is typical of a compact rear differential unit, where the housing volume is small and the fill tolerance is narrow.
- The 2.5 4WD hybrid rear differential, which also houses the rear electric motor, holds 1.7 liters — more than three times the capacity of the non-hybrid rear differential. The larger volume accommodates the combined lubrication demands of both the differential gearing and the integrated electric motor assembly.
- Under normal use conditions, the 2.5 4WD rear differential calls for a fluid check at 15,000 miles or 18 months. A check interval, rather than a change interval, means the fluid level and condition are inspected but replacement is not automatically required at that point.
- Under severe use conditions, the 2.5 4WD rear differential requires a fluid change at 30,000 miles or 36 months. Severe use classifications typically cover operating environments such as frequent towing, off-road driving, or repeated short trips that accelerate fluid degradation.
- The hybrid and plug-in hybrid rear differential and electric motor unit carries a normal-use check interval of 30,000 miles or 36 months — double the mileage interval of the non-hybrid rear differential under the same use condition.
- Under severe conditions, the hybrid and plug-in hybrid rear differential and electric motor unit has a change interval of 60,000 miles or 72 months, which is also double the corresponding interval for the non-hybrid 2.5 4WD rear differential under severe use.
- The RAV4 Prime Plug-in Hybrid shares the same 1.7-liter rear differential and electric motor fluid capacity and the same check and change intervals as the RAV4 2.5 4WD hybrid across both normal and severe use conditions.
- Across all configurations, the time-based component of each interval runs parallel to the mileage component, meaning whichever threshold — distance or elapsed time — is reached first would govern the service action.
