Additional Notes

  • Across all 650i Convertible and M6 Convertible configurations in the BMW 6 Series Convertible F12 (USA), the manual transmission service fill capacity is 1.6 liters. A service fill represents the amount of fluid added during a routine drain-and-refill procedure, as opposed to a full overhaul fill that accounts for every internal cavity.
  • An additional 0.6 liter is specified separately for the oil cooler across all six configurations. The oil cooler circuit holds fluid independently of the main transmission sump, so the two figures address distinct portions of the system rather than overlapping volumes.
  • The 650i Convertible rows covering 2011-2012, 2012-2015, and 2015-2018 carry no fluid change interval in the specifications. The M6 Convertible rows do carry explicit change intervals, reflecting a difference between the two model lines within the same F12 platform.
  • The BMW M6 Convertible for 2012-2013 carries a manual transmission fluid change interval of 45,000 miles under normal use conditions. Normal use, in the context of service intervals, generally refers to operation within standard temperature ranges and load cycles as defined by the manufacturer.
  • Starting with the 2013-2015 M6 Convertible, the change interval increases to 50,000 miles under normal use, a figure that also applies to the 2015-2018 M6 Convertible. The 2012-2013 interval of 45,000 miles is therefore specific only to that earlier configuration.
  • The capacity figures of 1.6 liters (service fill) and 0.6 liter (oil cooler) remain identical across all three M6 Convertible year ranges despite the shift in change interval between 2012-2013 and 2013-2015, indicating the volume specifications were not revised alongside the interval adjustment.
