Additional Notes
- The Subaru WRX STI 2.5T carries a power steering fluid capacity of 0.7 liter, a figure that applies to both the 2014-2018 and 2018-2021 model year spans covered in the specifications.
- A 0.7 liter capacity is characteristic of a service fill volume, reflecting the amount of fluid held within the reservoir and lines of a hydraulic power steering system rather than a larger overhaul quantity.
- The use condition recorded for both model year ranges is normal, meaning the 0.7 liter capacity figure is associated with standard operating conditions rather than a severe-use or first-change-only scenario.
- The 2018 model year appears in both row entries, placing it at the boundary between the two listed configurations, which indicates a production or specification transition point within that year.
