Additional Notes

  • All four configurations listed cover differential fluid for units sourced from automatic transmissions, meaning the differential is integrated within the automatic transaxle assembly rather than being a standalone unit.
  • The Renault 25, B29 (EU) 2.7 V6 Injection (1984-1988) carries a notably higher differential fluid capacity of 1.6 liters compared to the other three configurations, which fall in the 0.8-0.85 liter range.
  • The 2.8 V6 Injection (1988-1992) holds 0.85 liters despite sharing the V6 engine family with the earlier 2.7 V6 Injection, indicating a different differential housing or transaxle design between the two generations.
  • The 2.0 TS, GTS (1989-1992) and the 2.8 V6 Injection (1988-1992) share an identical capacity of 0.85 liters, while the 2.2 TX, GTX (1987-1992) sits slightly lower at 0.8 liters.
  • A uniform service interval of 60,000 km or 36 months applies across all four configurations under normal use conditions, meaning the interval is tied to whichever threshold is reached first.
  • The 36-month time limit alongside the 60,000 km mileage threshold means lower-mileage vehicles driven infrequently would still require a fluid change within three years under normal use.
  • The 2.0 TS, GTS entered the specification range starting in 1989, making it the latest introduction among the four configurations, while the 2.7 V6 Injection traces back to 1984 as the earliest.
