Opel Ascona A

Manual transmission fluid capacity & service interval

The Opel Ascona A requires manual transmission fluid with a capacity ranging from 0.6 liter to 1.1 liter depending on the configuration. Four configurations are covered in the data.

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

TypeSpecifications
Ascona 1.2 S (1972-1975)
  • Use: Normal
  • Capacity 0,6 liter
  • Code: 4/1
Ascona 1.6 (1970-1975)
  • Use: Normal
  • Capacity 1,1 liter
  • Code: 4/1
Ascona 1.6 S (1970-1975)
  • Use: Normal
  • Capacity 1,1 liter
  • Code: 4/1
Ascona 1.9 S (1970-1975)
  • Use: Normal
  • Capacity 1,1 liter
  • Code: 4/1

Additional Notes

  • The Opel Ascona A manual transmission fluid capacity splits into two distinct values across the model range: 0.6 liter for the 1.2 S and 1.1 liter for the 1.6, 1.6 S, and 1.9 S variants.
  • A manual transmission fluid capacity of 0.6 liter, as specified for the 1.2 S (1972-1975), is a relatively modest fill volume, consistent with a compact gearbox unit paired to a smaller displacement engine.
  • The 1.1 liter capacity shared by the 1.6, 1.6 S, and 1.9 S reflects a physically larger gearbox housing, which accommodates the greater torque output of the higher-displacement engines in those configurations.
  • All four configurations carry a normal use condition designation, meaning the stated capacities apply to standard operating conditions rather than severe-duty or first-change scenarios.
  • The 1.2 S entered the Ascona A lineup in 1972, while the 1.6, 1.6 S, and 1.9 S were available from 1970, giving the latter three a longer production span within the 1970-1975 model range.
  • No service interval mileage or time figure is listed for any of the four configurations, so the specifications are limited strictly to fluid capacity values under normal use conditions.
