BMW 3 series, F30 / F31 / F80 (USA)

Differential fluid capacity & service interval

BMW 3 series, F30 / F31 / F80 (USA) models utilize differential fluid with a capacity of 1 liter. Service intervals require a change every 50000 miles. The data covers 2 configurations.

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

TypeSpecifications
  • M3 (2015-2019)
  • Rear, with differential lock
  • Use: Normal
  • Capacity 1 liter
  • Change 50000 miles
  • M3 (2014-2015)
  • Rear, with differential lock
  • Use: Normal
  • Capacity 1 liter
  • Change 50000 miles

Additional Notes

  • The BMW M3 (F80) rear differential with differential lock carries a fluid capacity of 1 liter, which is a relatively modest fill volume consistent with a sealed limited-slip or electronically controlled locking differential unit rather than a larger open axle housing.
  • The 50,000-mile change interval applies under normal use conditions for both the 2014-2015 and 2015-2019 M3 configurations, meaning standard driving without the elevated thermal and mechanical stress associated with severe use classifications.
  • The 2014-2015 and 2015-2019 M3 rear differential specifications share identical capacity and interval values at 1 liter and 50,000 miles respectively, indicating no change in fluid service requirements across those two overlapping production groupings.
