Renault 6 (EU)

Manual transmission fluid capacity & service interval

Renault 6 (EU) manual transmission fluid capacity ranges from 1,15 to 1,8 liters. Service intervals include 15000 km or 12 months, and 500 hours. The data covers 6 configurations.

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

Additional Notes

  • The Renault 6 (EU) transaxle is a combined gearbox and differential unit, meaning the manual transmission fluid capacity listed covers the entire transaxle assembly rather than a standalone gearbox.
  • The R 1180 (0.8) transaxle holds 1.15 liters of fluid under normal service conditions, which is a notably smaller capacity than the 1.8-liter figure shared by both the R 1183 (1.0) and R 1181 (1.1) variants.
  • The 0.8-liter R 1180 and the 1.0-liter R 1183 share the same model year span of 1968-1980, yet the difference in transaxle fluid capacity between the two — 1.15 liters versus 1.8 liters — reflects a physically larger transmission unit in the higher-displacement variant.
  • The R 1181 (1.1) transaxle capacity of 1.8 liters matches the R 1183 (1.0) exactly, indicating both variants use a transaxle of equivalent fluid volume despite the difference in engine displacement.
  • Normal service intervals across all three variants are set at 15,000 km or 12 months, whichever comes first, applying a dual trigger that accounts for both mileage accumulation and calendar time.
  • An initial service interval of 500 hours is specified separately for all three variants. A 500-hour interval is a time-based measure rather than a distance-based one, and in automotive contexts of this era was sometimes used to define a break-in fluid change period for new or rebuilt components.
  • The 1.15-liter capacity of the R 1180 transaxle applies equally under both normal and initial service conditions, as does the 1.8-liter figure for the R 1183 and R 1181, meaning the fluid volume does not differ between the two service types for any of the three variants.
