Additional Notes
- The Proton Inspira carries a power steering fluid capacity of 1 liter across both the 1.8 and 2.0 engine variants for the 2011-2019 model years.
- A 1-liter capacity is characteristic of a compact hydraulic power steering reservoir, reflecting a system sized for a mid-range sedan rather than a larger vehicle platform.
- Both the 1.8 and 2.0 variants share the P3-90A transmission designation, and both return the same 1-liter power steering fluid capacity, indicating no variation between engine displacements in fluid volume requirements.
- The capacity figure of 1 liter applies under normal use conditions for both configurations, meaning standard operating environments without the elevated demands associated with severe-duty classifications.
