The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| X1/9 1500 (1978-1981) |
|
| X1/9 1300 (1972-1978) |

Additional Notes
- Both the X1/9 1300 and X1/9 1500 share an identical brake fluid capacity of 0.44 liter, which reflects the total volume held within the hydraulic brake system rather than a full overhaul drain-and-fill quantity.
- The 500 km check interval applies to normal use conditions across both engine variants, placing brake fluid inspection among the more frequent service tasks on the maintenance schedule.
- A 500 km check interval for brake fluid is notably short by general automotive standards, which typically place brake fluid inspection at several thousand kilometers, suggesting the hydraulic system on the Fiat X1/9 (EU) warranted close monitoring at early service intervals.
- The capacity figure of 0.44 liter remains consistent across the 1972-1978 and 1978-1981 model year spans, indicating no change in hydraulic system volume between the 1300 and 1500 engine configurations.
