Proton Inspira

Brake fluid capacity & service interval

Proton Inspira uses brake fluid with a capacity range between min and max. Service intervals include checks at 20000 km or 12 months and changes at 40000 km or 24 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Inspira 1.8, P3-90A (2011-2019)
  • Use: Normal
  • Between min and max.
  • Check 20000 km/ 12 months
  • Change 40000 km/ 24 months
Inspira 2.0, P3-90A (2011-2019)
  • Use: Normal
  • Between min and max.
  • Check 20000 km/ 12 months
  • Change 40000 km/ 24 months

Additional Notes

  • The Proton Inspira brake fluid level is maintained between the minimum and maximum reservoir marks rather than expressed as a fixed volume, which is standard practice for hydraulic brake systems where fluid is not consumed but displaced within a closed circuit.
  • Both the 1.8 and 2.0 engine variants of the Inspira, under the P3-90A platform spanning 2011-2019, share identical brake fluid service intervals, with a check interval of every 20,000 km or 12 months and a change interval of every 40,000 km or 24 months.
  • The check interval of 20,000 km or 12 months applies under normal use conditions, meaning the fluid level inspection falls due at whichever threshold, distance or time, is reached first.
  • The change interval of 40,000 km or 24 months under normal use conditions means the fluid is fully replaced on a fixed cycle, which accounts for brake fluid's hygroscopic nature and its gradual absorption of moisture over time regardless of mileage.
  • The 1.8 and 2.0 Inspira variants carry the same P3-90A platform designation across 2011-2019, and the uniformity of brake fluid specifications across both engine displacements reflects a shared hydraulic brake system architecture between the two configurations.
