Additional Notes

  • The rear differential capacity across all Subaru BRZ configurations from 2012 onward is 1.15 liters, a figure consistent with a service fill rather than a full overhaul, as overhaul capacities typically account for additional volume in disassembled components.
  • The 2.0-liter BRZ from 2012-2017 carries a change interval of 30,000 km or 48 months under normal use conditions, meaning whichever threshold arrives first triggers the service requirement.
  • Both the standard rear differential and the limited slip differential variant on the 2012-2017 BRZ 2.0 share the same 1.15-liter capacity and the same 30,000 km / 48-month change interval, despite the limited slip unit containing additional friction components that differentiate fluid compatibility requirements.
  • The 2017-2019 BRZ 2.0 retains the 1.15-liter capacity and 30,000 km change interval but no longer carries the 48-month time-based threshold, making mileage the sole governing criterion for that generation.
  • The same interval structure applies to both the standard and limited slip rear differential variants on the 2017-2019 BRZ 2.0, with both specifying only the 30,000 km distance marker and no accompanying time limit.
  • The BRZ 2.4 from 2023 onward introduces an inspection step not present in earlier generations, with a fluid check interval of 15,000 km or 12 months preceding the full change interval of 30,000 km or 48 months under normal use conditions.
  • The 2.4-liter BRZ limited slip differential maintains the same 1.15-liter capacity as the 2.0-liter variants, indicating no volumetric change in the rear differential housing between the two engine generations.
