Additional Notes
- Across all four configurations in the Buick Regal E2XX lineup for 2017-2020, the brake fluid capacity specification is expressed as a reservoir fill range rather than a fixed volume, with the accepted level falling between the minimum and maximum marks on the reservoir.
- The 60-month change interval applies uniformly under normal use conditions to the 2.0L Turbo FWD, 2.0L Turbo AWD, TourX 2.0L Turbo AWD, and GS 3.6L V6 AWD configurations.
- A 60-month interval means brake fluid is scheduled for replacement every five years, which reflects the hygroscopic nature of brake fluid and its tendency to absorb moisture over time, lowering its boiling point.
- The Regal GS 3.6L V6 AWD shares the same 60-month normal-use interval as the four-cylinder turbocharged variants, indicating no differentiation in brake fluid service scheduling between the V6 and 2.0L Turbo powertrains.
- The reservoir-based fill specification, rather than a precise fluid volume, is consistent with hydraulic brake system servicing, where the reservoir level is the practical reference point during maintenance rather than a measured quantity.
- The TourX 2.0L Turbo AWD, despite being a wagon body style variant, carries the same hydraulic brake system service interval of 60 months under normal use as the sedan-based Regal configurations.
