Fiat X1/9 (EU)

Manual transmission fluid capacity & service interval

Fiat X1/9 (EU) manual transmission fluid capacity is 3 liters. Service intervals include checking at 10000 km and changing at 30000 km. The data covers 2 configurations.

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

TypeSpecifications
X1/9 1500 (1978-1981)
  • Use: Normal
  • Capacity 3 liter
  • Check 10000 km
  • Change 30000 km

X1/9 1300 (1972-1978)
  • Use: Normal
  • Capacity 3 liter
  • Check 10000 km
  • Change 30000 km
  • Code: 4/1

Additional Notes

  • Both the X1/9 1300 and X1/9 1500 share an identical manual transmission fluid capacity of 3 liters, which reflects a service fill figure for the transaxle unit rather than a full overhaul or dry-fill measurement.
  • A transaxle combines the transmission and final drive into a single housing, meaning the 3-liter capacity covers the fluid needs of both functions within one integrated assembly.
  • The Fiat X1/9 (EU) specifies a fluid check interval of 10,000 km under normal use conditions, which is a shorter interval than the full change, serving as a periodic top-up or level verification point between full services.
  • The full fluid change interval is set at 30,000 km under normal use conditions, applying equally to both the 1300 and 1500 engine variants across the 1972-1981 production span.
  • The 1300 variant, covering model years 1972-1978, and the 1500 variant, covering 1978-1981, carry no variation in transaxle fluid capacity or service intervals despite differing engine displacements.
