Iso Grifo
Brake fluid capacity & service interval
Iso Grifo brake fluid capacity is 0,7 liter. Service intervals include checking at 60000 km and changing at 100000 km or 60 months. The data covers 3 configurations.

Additional Notes
- The Iso Grifo brake fluid capacity is listed at 0.7 liter across the GL300, GL340, and GL350 variants, reflecting the total volume of the combined hydraulic brake and clutch system rather than the brake circuit alone.
- A shared hydraulic circuit serving both braking and clutch actuation is a design arrangement common to several European grand touring cars of the 1960s and 1970s, meaning a single fluid reservoir and line network handles both functions simultaneously.
- The GL300, GL340, and GL350 all carry identical capacity, check, and change intervals, indicating no differentiation in brake fluid service requirements across the three Grifo Lusso variants despite their differing engine designations.
- The check interval is set at 60,000 km under normal use conditions, which represents a mid-cycle inspection point intended to verify fluid condition and system integrity before the full change interval is reached.
- The change interval is specified at 100,000 km or 60 months, whichever comes first. The 60-month threshold, equivalent to five years, reflects the hygroscopic nature of brake fluid, which absorbs moisture over time and degrades regardless of distance driven.
- A time-based limit of 60 months alongside a distance-based limit of 100,000 km means that low-mileage vehicles are still subject to a mandatory fluid change on a calendar basis, as moisture absorption occurs independently of vehicle use.
