Additional Notes
- The Subaru Outback BT (EU) differential fluid specifications cover two engine variants: the 2.4T, with a starting year of 2022, and the 2.5i, with a starting year of 2021.
- Both variants carry two separate differential fluid entries each: one for the differential fed from the CVT and one for the rear differential, meaning each engine configuration requires independent fluid servicing at two locations.
- The front differential (from CVT) on the 2.4T holds 1.15-1.25 liters, expressed as a range rather than a fixed value, which is typical for fill procedures where fluid level is confirmed by overflow rather than a precise measured quantity.
- The 2.5i front differential (from CVT) has a slightly higher capacity range of 1.2-1.3 liters compared to the 2.4T's 1.15-1.25 liters, indicating a measurable difference between the two engine variants at this location.
- Both the 2.4T and 2.5i share an identical rear differential capacity of 0.8 liters, a fixed single value rather than a range, which generally reflects a more straightforward drain-and-fill procedure with a defined sump volume.
- All four differential fluid entries across both variants are rated for normal use conditions, and under those conditions the specified change interval is 60,000 km or 48 months, whichever comes first.
- A check interval of 30,000 km or 24 months is specified for all four entries, placing a fluid inspection at the halfway point of each full change cycle under normal use conditions.
