Additional Notes

  • The INFINITI EX/J50 differential specifications cover two distinct engine variants across the model range: the EX35 (2008-2010) and the EX 3.7 (2012-2013), with front differential data appearing exclusively in AWD configurations.
  • The front differential capacity is 0.65 liter across all AWD configurations, while the rear differential holds 1.4 liters in every listed configuration, making the rear unit more than twice the fluid volume of the front.
  • The rear differential capacity of 1.4 liters is consistent across both the AWD and rear-wheel-drive variants of the EX 3.7 (2012-2013), as well as across all EX35 configurations from 2008-2010.
  • EX35 AWD and rear-wheel-drive models from 2008-2010 carry a check interval of 15000 miles or 12 months for both front and rear differentials, with no fluid change interval listed for normal use conditions.
  • The EX 3.7 (2012-2013) models show a reduced normal-use check interval of 10000 miles or 12 months compared to the 15000-mile interval specified for the earlier EX35 models, while the mileage threshold drops by a third between the two generations.
  • Under severe use conditions, the EX 3.7 (2012-2013) adds a fluid change interval of 20000 miles or 24 months to both front and rear differentials, a requirement absent from the normal use rows where only a check interval is specified.
  • The severe-use check interval for the EX 3.7 (2012-2013) remains at 10000 miles or 12 months, identical to the normal-use check interval, meaning the distinction between normal and severe use for this model affects the change schedule rather than the inspection frequency.
  • No severe-use rows appear for any EX35 configuration from 2008-2010, meaning fluid change intervals under demanding operating conditions are only specified for the 2012-2013 model year range within these specifications.
