Additional Notes
- The power steering fluid specification for the Buick Lucerne across all listed configurations is expressed as a reservoir level range rather than a discrete fill volume, meaning service involves verifying the fluid sits between the marked minimum and maximum points on the reservoir.
- All four configurations carry a normal use condition designation, which ties the min-to-max level specification to standard operating circumstances rather than severe or first-change scenarios.
- The 3.9 FlexFuel V6, available in 2011, shares an identical power steering fluid level specification with the standard 3.9 V6 that spans 2008-2011, reflecting no differentiation between the two engine variants for this system.
- The 4.6 V8 appears under both a 2008-2011 range entry and a standalone 2011 entry, yet both reference the same min-to-max level specification under normal use, consistent with the V6 configurations.
