Additional Notes
- The Opel Commodore C power steering system carries a capacity of 1 liter across both the 2.5 E and 2.5 S variants, spanning the 1977-1982 model years.
- A 1-liter capacity is characteristic of a relatively compact power steering reservoir, consistent with the rack-and-pinion or recirculating-ball hydraulic assist systems common to passenger cars of the late 1970s and early 1980s.
- Both the 2.5 E and 2.5 S share an identical 1-liter power steering fluid capacity, indicating no variation between the two trim levels in terms of hydraulic system volume.
- The specifications are listed under normal use conditions for both variants, meaning the capacity figure of 1 liter applies to standard operating environments rather than severe-duty or first-change scenarios.
