Lamborghini R4

Power steering fluid capacity & service interval

Lamborghini R4 uses power steering fluid with a capacity of 71 liters. Service intervals include checking every 300 hours and changing every 1200 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The Lamborghini R4 power steering fluid shares a combined reservoir with the transaxle and hydraulic system, meaning the 71-liter capacity figure reflects the total shared fluid volume across all three systems rather than a dedicated power steering reservoir alone.
  • All four configurations of the R4 covered in the 2005-2009 range, the R4.85, R4.95, R4.105, and R4.110, carry an identical 71-liter capacity for the transaxle/hydraulic/power steering system.
  • A 71-liter combined system capacity is a substantial volume, consistent with large agricultural or industrial machinery where hydraulic demand from implements, steering, and drivetrain components is served by a single shared sump.
  • The fluid check interval is set at 300 hours under normal use conditions, which in operational terms means periodic inspection well before a full drain cycle is due.
  • The change interval is specified at 1200 hours or 12 months under normal use conditions, whichever comes first, applying a dual threshold that accounts for both time-based fluid degradation and accumulated operating hours.
  • The 1200-hour change interval means a machine operating at high annual hours could reach the hour-based threshold well before the 12-month calendar mark, while a lightly used machine would reach the annual threshold first.
  • The uniform specifications across the R4.85, R4.95, R4.105, and R4.110 variants indicate no differentiation in fluid capacity or service intervals based on engine output within the 2005-2009 model range.
