Additional Notes

  • The INFINITI EX, J50 (EU) automatic transmission fluid capacity differs between engine variants, with the EX30D requiring 10 liters and the EX37 requiring 9.2 liters.
  • The 10-liter figure for the EX30D reflects a full transmission fill volume, which is typical of a complete fluid exchange or overhaul rather than a partial service top-up.
  • The EX37 holds 9.2 liters across both its 2008-2010 and 2010-2013 model year ranges, indicating no change in transmission fluid capacity between those periods.
  • The EX30D from 2010-2011 carries a check interval of 15,000 km or 12 months under normal use conditions, while the 2011-2013 range extends that interval to 20,000 km under the same conditions.
  • The shift from a 15,000 km to a 20,000 km check interval for the EX30D between the 2010-2011 and 2011-2013 specifications represents a 33% increase in the distance-based service period.
  • The EX37 maintains a consistent 15,000 km or 12 months check interval under normal use across both its 2008-2010 and 2010-2013 configurations, with no revision to the interval during that span.
  • All four rows carry a normal use condition designation, meaning none of the listed intervals account for severe driving cycles such as frequent towing, extreme temperatures, or stop-and-go urban operation.
