i'm a fan of the single time full fluid exchange using the cooler lines.
I'm part of the incremental 2 qt drain crowd. At my maintenance schedule this comes every 10K miles. If done on schedule, the incremental method is passable as the additive package isn't depleted. If one is driving the 30K miles on the fluid then do as PD mentions.
