Mazda Luce/Legato/929(L) (EU)

Power steering fluid capacity & service interval

Mazda Luce/Legato/929(L) (EU) uses power steering fluid with a capacity of 0,25 liter. Service intervals include checks at 18000 km or 20000 km/12 months. The data covers 6 configurations.

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

Additional Notes

  • All six configurations listed carry a steering box rather than a rack-and-pinion arrangement. A steering box holds fluid within a sealed recirculating-ball or worm-and-sector housing, which is why the capacity across every entry is a modest 0.25 liter.
  • The 0.25-liter figure represents the fluid volume held inside the steering box housing itself. This is a service fill capacity, not a reservoir top-up volume, reflecting the compact, self-contained nature of steering box designs common to vehicles of this era.
  • The Mazda Luce/Legato/929L 1500 (SUA, 1966-1972) and 1800 (SVA, 1968-1973) share identical specifications: 0.25-liter capacity and an 18,000 km check interval under normal use conditions.
  • The 18,000 km check interval applied to the LA2/3 generation (1973-1977 for the 1800 and 1975-1977 for the 2000) is a distance-only trigger, with no time-based component specified alongside it.
  • With the introduction of the LA4/5 generation in 1977, both the 1800 and 2000 variants moved to a dual-condition check interval of 20,000 km or 12 months, whichever occurs first. Adding a time-based limit alongside the distance figure accounts for vehicles that accumulate low annual mileage, where fluid degradation over time becomes the governing factor rather than use alone.
  • The capacity remained unchanged at 0.25 liter across the LA4/5 generation despite the revised check interval, indicating the steering box design retained the same fluid volume while the service schedule was updated independently.
  • The 1800 and 2000 engine variants within the same LA2/3 generation (1973-1977 and 1975-1977 respectively) share the same 0.25-liter capacity and 18,000 km check interval, showing no differentiation in steering system specifications between the two displacements in that body generation.
