Best Oil for our N55 Turbo Motors?
I'm sure this is an old subject, but I'm new to this (turbo) engine platform and was wondering what everyone else is using for the "Life Blood" of their engine? I strongly feel engine oil is just that, the "Life Blood" of your motor. I've read a lot of different things about addatives in various different engine oils being good and or bad for the turbo. I'm sure BMW oil is good enough, but there's Always something better. I've been thinking Motul or Liqui Moly, possibly even Red Line. Any input and advice would be greatly appreciated. Thanks in advance...
