Additional Notes

  • The Buick Regal Epsilon II (USA / CAN) manual transaxle holds 2.2 liters of fluid across both available engine configurations for 2011-2012.
  • A transaxle combines the transmission and drive axle into a single unit, and a 2.2-liter fill capacity is consistent with a compact front-wheel-drive manual transaxle design.
  • The 2.2-liter capacity listed for both configurations represents a service fill level, meaning the amount of fluid required during a standard drain-and-refill procedure rather than a full overhaul.
  • The 164 kW 2.0L VVT Turbo variant covers model years 2011-2012, while the higher-output 201 kW GS variant is specific to 2012 only, yet both share the identical 2.2-liter transaxle fluid capacity.
  • Both rows carry a normal use condition, meaning the 2.2-liter capacity figure applies under standard operating circumstances rather than severe-duty or first-change-only scenarios.
