INFINITI M, Y51 (EU)

Differential fluid capacity & service interval

INFINITI M, Y51 (EU) differential fluid capacity ranges from 1,15 to 1,4 liters. Service intervals include checks at 15000 km or 12 months and 20000 km or 12 months, with changes at 30000 km or 24 months. The data covers 12 configurations.

Additional Notes

  • The rear differential fluid capacity for the INFINITI M Y51 (EU) splits into two distinct values depending on the engine variant. The M30d and M35h share a 1.15-liter capacity, while the M37 requires a larger 1.4-liter fill. A higher capacity figure in a rear differential generally reflects a larger housing or a more robust gear set designed to handle greater torque loads.
  • The 1.15-liter capacity applies uniformly across all M30d production spans (2010-2011 and 2011-2014) and all M35h spans (2011-2012 and 2012-2014), with no variation between the earlier and later sub-ranges for either variant.
  • The M37 retains the same 1.4-liter rear differential capacity across both its 2010-2012 and 2012-2014 sub-ranges, indicating no housing or unit change between those periods despite the split in specification entries.
  • Under normal use conditions, the M30d (2011-2014) carries a fluid check interval of 20,000 km or 12 months. The earlier M30d (2010-2011) under normal use specifies a shorter 15,000 km or 12-month check interval, reflecting a tighter schedule for the earlier production span.
  • Under severe use conditions, the M30d (2010-2011) and M30d (2011-2014) both specify a fluid check at 15,000 km or 12 months and a fluid change at 30,000 km or 24 months. The change interval is absent from the normal-use rows, meaning a mandatory fluid replacement is only scheduled when severe conditions apply.
  • The M35h and M37 variants specify a 15,000 km or 12-month check interval under normal use across all their respective sub-ranges. This is shorter than the 20,000 km normal-use check interval seen on the later M30d (2011-2014), placing the diesel variant on a more relaxed inspection schedule in its later production span.
  • Severe-use conditions for the M35h (2011-2012 and 2012-2014) and M37 (2010-2012 and 2012-2014) all include a fluid change at 30,000 km or 24 months, consistent with the severe-use pattern across the full M Y51 (EU) range. Severe use typically encompasses conditions such as frequent towing, off-road driving, or repeated short-distance trips that accelerate fluid degradation.
  • The M35h is a hybrid petrol-electric variant, yet its rear differential fluid capacity and service intervals align with the M30d diesel rather than the larger M37 petrol. Both the M35h and M30d share the 1.15-liter rear differential fill, suggesting a common rear differential unit between those two variants.
