Additional Notes

  • All six Alfa Romeo 90 variants listed across the 1984-1987 production span share an identical manual transaxle fluid capacity of 2.85 liters. A transaxle combines the transmission and final drive into a single housing, and a unified capacity figure across such a range of engine configurations points to a common transaxle unit used throughout the 90 lineup.
  • The 2.85-liter figure applies to a service fill, meaning the quantity of fluid required during a routine drain-and-refill procedure on an assembled unit. Service fill volumes are typically lower than overhaul capacities, which account for fluid retained in passages and components during a full disassembly.
  • Under normal use conditions, the specified check interval is 20,000 km. A fluid level check at this interval does not involve a full drain; rather, the level is inspected and topped up if necessary, serving as a routine monitoring step between full changes.
  • The fluid change interval under normal use conditions is set at 40,000 km or 24 months, whichever comes first. The dual-trigger structure means time elapsed can mandate a change even when the distance threshold has not been reached, which is relevant for vehicles driven infrequently.
  • The 90 2.0 V6 Iniezione covers a narrower production window of 1986-1987, compared to the 1984-1987 span of most other variants, yet carries the same transaxle fluid capacity and service intervals as the rest of the range.
  • The 90 2.4 TD is the sole diesel variant among the listed configurations. Despite the differing mechanical demands of a turbocharged diesel engine relative to the petrol units in the lineup, the transaxle fluid capacity and service schedule remain identical across all variants at 2.85 liters, 20,000 km checks, and 40,000 km or 24-month changes.
  • The 90 2.5 V6 Iniezione Quadrifoglio Oro, the range-topping trim designation among the listed variants, shares the same transaxle specifications as the base 1.8-liter model. The Quadrifoglio Oro designation historically indicated a higher equipment level rather than a mechanically distinct drivetrain in this context.
