There are literally full pages of 'oil threads' here...some reading via Search Tab will glaze the eyes and make your hair hurt.
Red Line makes good stuff by most accounts, (I use their trans stuff in my manual trans boxes), but I don't think the RL oil will reduce your oil usage.
Our '01 3.0 5 spd experiences similar consumption, esp on long fast highway trips, and has since about 'new'. Fwiw, your consumption is within BMW specs, even when it was brand new...10 years later it is not uncommon.
Change if you like, (I went to M1 0W-40 a few years ago which reduced consumption slightly), but I just don't think you will see a real difference.
