Mazda Grand Familia/818 (EU)

Power steering fluid capacity & service interval

Mazda Grand Familia/818 (EU) power steering fluid capacity is 0,25 liter. Service intervals consist of 20000 km or 12 months. Data covers 2 configurations.

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

TypeSpecifications
Grand Familia 818 1300, STC (1973-1978)
  • Use: Normal
  • Capacity 0,25 liter
  • Check 20000 km/ 12 months
Grand Familia 818 1600, SN4 (1973-1978)
  • Use: Normal
  • Capacity 0,25 liter
  • Check 20000 km/ 12 months

Additional Notes

  • Both the 1300 STC and 1600 SN4 engine configurations share an identical power steering fluid capacity of 0.25 liter, which is a notably small volume consistent with a steering box design rather than a rack-and-pinion system with a remote reservoir.
  • The Mazda Grand Familia/818 (EU) uses a steering box arrangement across both engine variants, a mechanical configuration common in vehicles of the early-to-mid 1970s that typically holds less fluid than later rack-and-pinion power steering systems.
  • The specified check interval for power steering fluid is 20,000 km or 12 months, whichever comes first, applied under normal use conditions for both the 1300 STC and 1600 SN4 variants across the 1973-1978 production span.
  • The 0.25 liter figure represents a service-level capacity reference rather than a full overhaul fill, as steering box checks at defined intervals are concerned with maintaining correct fluid level rather than complete fluid replacement.
  • No variation exists between the 1300 STC and 1600 SN4 in terms of power steering fluid capacity or check interval, meaning the steering box specification appears to be shared hardware independent of engine displacement.
