Opel Rekord

Additional Notes

• The Opel Rekord 1.9 from 1966-1971 carries a 5.6-liter capacity figure with no refill designation, indicating a total dry or overhaul fill rather than a routine service top-up quantity. All other configurations across the 1966-1977 range list 2.5 liters marked as a refill capacity, which represents the amount returned to the transmission during a fluid drain service rather than the full system volume.
• The shift from a total fill figure to a 2.5-liter refill figure between the Rekord 1.9 (1966-1971) and the Rekord 1.9 (1972-1977) suggests a change in how the specification was recorded across the two generation periods, even though the engine displacement remained the same.
• The 1.7 and 1.7 S variants from 1966-1971 share identical automatic transmission fluid specifications, including the 2.5-liter refill capacity, the 10,000 km or 6-month check interval, and the 40,000 km or 24-month change interval.
• The Rekord 1.7 S specification carries forward unchanged from the 1966-1971 period into the 1972-1977 period, with the same 2.5-liter refill capacity and the same check and change intervals applying across both generation spans.
• The Rekord 2.1 D from 1972-1977, the only diesel-engined configuration in the listed data, shares the same 2.5-liter refill capacity and service intervals as the petrol-engined variants of the same period.
• All six configurations share a check interval of 10,000 km or 6 months, whichever comes first, under normal use conditions. The time-based component of the interval means a vehicle covering low annual mileage would still require a fluid check within six months regardless of distance traveled.
• The change interval of 40,000 km or 24 months applies uniformly across all listed configurations under normal use conditions. The 24-month time limit means the fluid would require replacement within two years even if the distance threshold had not been reached.
