You are not paying attention. Mobil 1 0w-40 is excellent stuff, stick with it. On the other hand, avoid Lucas oil Stabilizer like the plague. If you are changing every 5K, it almost doesn't matter what you are using. Don't worry. Don't sweat LL-01 vs LL-04. I still like Castrol 0W-30 fwiw. Best advice is pick one of the approved oils (there are only 4 choices, see previous post), or the BMW 5W-30 and then stick with it, be consistent.
