At one time we had three BMW vehicles with the M54 engine. All were driven by the same drivers, on the same roads, in the same ambient temperatures. All were purchased new and broken in the same way. All used the same oil. The E53 consistently used more oil, over several years of concurrent comparison. The only difference was that it was a heavier vehicle. The engine was working harder. (Which incidentally meant that it warmed up faster). In terms of oil consumption, I don't think CCV design had anything to do with it.
