I was thinking, would that (at least on the long run) cause oil slugging, low flow and accumulation of carbon deposit?
First, the CVT in the Nissan V6's is quite good and they do last. Keeping it at one RPM on the highway will concentrate the wear in one location on the pulleys. Not a bad idea to vary speed and RPM.
2000 RPM is plenty high to circulate oil. Try standing next to the engine (really) when it's operating at 2000 RPM in neutral, you'll see what I mean.
