Additional Notes
- All four configurations listed for the Buick Lucerne (USA / CAN) share the same brake fluid specification: the hydraulic brake system reservoir is to be filled between the minimum and maximum marks, rather than to a fixed volume figure.
- A "between min and max" specification is typical for brake fluid reservoirs, where the acceptable level is defined by physical markers on the reservoir body rather than a precise measured capacity.
- The 3.9 FlexFuel V6 variant carries a model year range of 2011 only, while the 3.9 V6 and 4.6 V8 configurations span 2008-2011, reflecting differences in when each engine was offered across the Lucerne lineup.
- The 4.6 V8 appears under two separate row entries: one covering 2008-2011 and another limited to 2011, both sharing identical brake fluid level specifications for the hydraulic brake system under normal use conditions.
- All configurations are designated under normal use conditions, meaning no separate severe-use interval or alternative specification is listed for the brake fluid system across any of the four Lucerne variants.
