Additional Notes

  • The Opel Combo A 1.3 (1986-1989), 1.6 (1986-1990), 1.6 D (1986-1989), and 1.6i (1991-1993) all share a manual transaxle fluid capacity of 2.1 liters, indicating a consistent gearbox unit across those engine variants.
  • The 1.4i (1991-1993) carries a notably lower manual transaxle capacity of 1.7 liters, the smallest among all Combo A variants listed, which reflects a physically smaller transaxle assembly suited to that engine.
  • The 1.7 D (1989-1993) stands apart with a manual transaxle capacity of 3.1 liters, the largest figure across all Combo A configurations listed. A higher fluid volume in a diesel-powered variant typically corresponds to a heavier-duty gearbox designed to handle greater torque loads.
  • All six Combo A variants share an identical fluid check interval of 15,000 km or 12 months under normal use conditions, whichever comes first. The time-based limit of 12 months ensures fluid condition is assessed even in low-mileage applications where the distance threshold may not be reached within a year.
  • The specifications cover manual transaxle units throughout, meaning the gearbox and final drive share a common fluid reservoir. A transaxle arrangement combines the transmission and differential into a single housing, so the listed capacities account for both functions together.
  • The 1.6 D (1986-1989) is the only diesel variant among the earlier production years, yet its 2.1-liter transaxle capacity matches the petrol-engined 1.3 and 1.6 of the same period, suggesting a shared gearbox platform across those early models regardless of fuel type.
