Additional Notes
- The front differential on the WRX 2.0T, sourced from the CVT unit, holds between 1.3 and 1.5 liters, a notably larger capacity than the rear differential on the same engine, which ranges from 0.8 to 1 liter.
- The rear differential on the Subaru WRX STI 2.5T (2014-2019) carries a fixed capacity of exactly 1 liter, whereas the WRX 2.0T rear differential is specified with a range of 0.8 to 1 liter, reflecting a tolerance window rather than a single target fill volume.
- A capacity expressed as a range, such as 0.8-1 liter or 1.3-1.5 liters, typically indicates an acceptable service fill window rather than a precise overhaul measurement, allowing for minor variation during a drain-and-refill procedure.
- Across all three differential entries for the 2014-2019 model range, the check interval is set at 30,000 km or 24 months under normal use conditions, whichever comes first.
- The fluid change interval for all listed differentials under normal use is 60,000 km or 48 months, meaning a full fluid replacement is due at twice the frequency of a fluid level inspection.
- The WRX 2.0T carries two separate differential fluid specifications, one for the CVT-sourced front differential and one for the rear, while the WRX STI 2.5T lists only a rear differential entry under the same model years.
