The risk with “wet engines” that burn a quart every 2k is carbon build up leading to pre-detonation and possible engine damage.

Our 2001 X5 4.8i consumed something like 1qt/2k. Unless we drove her pretty hard, she would develop a stutter at high RPM. The dealer offered to pull/clean the heads (at my expense). But he also suggested that I could “blow it out” with some spirited high rev runs in the country. I opted for the latter

At the time I was regularly hauling a utility trailer of stuff to the cabin I was building. So on these runs I’d drop her down to sport and hold her into a lower gear as I accelerated up hill with a fully loaded trailer. After blowing her out in 2nd, I’d work my way up the gears on the next hill untill she didn’t stutter in 5th at 6,000 rpm. Of course, blowing her out in 5th required a close watch for cars with those special logos/lights.
