Opel Combo B

Manual transmission fluid capacity & service interval

Opel Combo B manual transmission fluid capacity is 1,6 liters. Service intervals occur every 24 months or 30000 km. The data covers 6 configurations.

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

Additional Notes

  • All six Opel Combo B configurations listed across the 1993-2001 model range share an identical manual transaxle fluid capacity of 1.6 liters. In the context of manual transmission servicing, a transaxle combines the gearbox and differential into a single housing, and the 1.6-liter figure represents the service fill volume for that combined unit.
  • The 1.6-liter capacity applies uniformly across petrol and diesel variants, including the 1.2i, 1.4, 1.4i, 1.4i 16V, and both production periods of the 1.7 D. No variation in fluid volume exists between engine types within the Combo B range as specified.
  • The 1.7 D diesel engine appears in two distinct production periods: 1993-1996 and 1996-2001. Both periods carry the same 1.6-liter transaxle capacity and the same check interval, indicating no mechanical revision to the transmission unit between those periods affected fluid volume requirements.
  • The 1.4i 16V variant, produced from 1994-2000, represents the highest-output petrol configuration in the listed range. Despite the added complexity of a 16-valve cylinder head, the manual transaxle fluid capacity remains at 1.6 liters, consistent with all other Combo B variants.
  • The specified check interval for all Combo B manual transaxle entries is 24 months or 30,000 km, whichever comes first, under normal use conditions. A time-based interval of 24 months runs alongside the distance-based threshold, meaning low-mileage vehicles still reach a service point on the calendar schedule alone.
  • The 30,000 km distance threshold in the check interval is relatively frequent by general manual transmission standards, where many manufacturers specify longer drain intervals. A check interval, as opposed to a change interval, typically involves inspecting the fluid level and condition rather than a mandatory full drain and refill.
  • The normal use condition designation applies to all six rows without any severe-use alternative listed. In transmission service contexts, severe use typically covers conditions such as frequent towing, stop-and-go urban driving, or operation in extreme temperatures, none of which alter the specified interval in the Combo B data as presented.
