My BMW agent recommended to just keep it under about 3000 rpm for the first 1500 miles or so. with the 8 speed auto, I can still go about 100-110 mph on the autobahn and keep it at about 2900 rpm. my warm up period is always on the country roads, so it's naturally slower and easier. I also try to avoid small hops, but sometimes I can't avoid driving around post here...
