Iso Grifo

Power steering fluid capacity & service interval

Iso Grifo power steering fluid capacity is 0,3 liter. Service intervals consist of a check every 5000 km. The data covers 3 configurations.

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

Additional Notes

  • The Iso Grifo Lusso GL300, GL340, and GL350 all share an identical power steering fluid capacity of 0.3 liter, which is a notably small volume consistent with a steering box unit rather than a rack-and-pinion or full hydraulic pump reservoir system.
  • The steering box note applies uniformly across the GL300, GL340, and GL350 variants spanning 1963-1974, indicating a recirculating ball or worm-type steering box as the common steering mechanism across all three configurations.
  • A 0.3 liter capacity in a steering box context typically represents the fluid held within the box housing itself, rather than a separate remote reservoir, which explains the relatively low volume compared to modern power steering systems.
  • The specified check interval of 5000 km applies under normal use conditions across all three Grifo Lusso variants, meaning the fluid level in the steering box is to be inspected at each 5000 km service point rather than replaced on a fixed drain-and-fill schedule.
  • No variation in capacity or check interval exists between the GL300, GL340, and GL350 designations, suggesting the steering box assembly was a shared component across all three engine or trim configurations within the 1963-1974 production span.
