Alfa Romeo Spider, 115 (EU)

Differential fluid capacity & service interval

Alfa Romeo Spider, 115 (EU) models require differential fluid with a capacity of 1,4 liters. Service intervals include checking at 20000 km and changing at 40000 km or 24 months. The data covers 7 configurations.

Additional Notes

  • A uniform rear differential capacity of 1.4 liters applies across all Alfa Romeo Spider 115 configurations covered in these specifications, spanning both the 1.6 and 2.0 engine variants as well as the Quadrifoglio Verde trim, for the full 1983-1993 period.
  • The 1.4-liter figure represents a service fill capacity, meaning the volume of fluid required when refilling the differential during routine maintenance rather than a full overhaul or dry-build quantity.
  • A check interval of 20,000 km is specified across all configurations, indicating the mileage point at which fluid level and condition are to be inspected without necessarily performing a full drain and refill.
  • The change interval is set at 40,000 km or 24 months, whichever comes first, applying uniformly under normal use conditions to every variant listed, including the 1.6, 2.0, and 2.0 Quadrifoglio Verde.
  • The dual-trigger change interval of 40,000 km or 24 months reflects that time-based degradation of differential fluid is treated as equally relevant as mileage accumulation under normal operating conditions.
  • All intervals and capacities in these specifications are designated for normal use conditions, meaning they are not adjusted for severe-duty operation such as towing, track use, or extreme climates.
  • The Alfa Romeo Spider 2.0 (1983-1989) appears with two distinct rear differential entries: one for the standard open differential and one for the limited-slip differential. Both share the same 1.4-liter capacity and identical check and change intervals, though limited-slip differentials typically require a fluid formulation compatible with friction modifier requirements to prevent chatter.
  • No specification variation exists between the 1983-1989 and 1990-1993 model year groupings for any given engine variant, as capacity, check interval, and change interval remain at 1.4 liters, 20,000 km, and 40,000 km/24 months respectively across both periods.
