I dont know what oil bmw uses, but are you guys saying that you are using a different type of oil than what BMW uses at the dealership?

since I purchased my 4.8is in i think june, i did the oil change once at a german independent shop so im not sure what oil they use. my truck doesnt currently has the blue smoke issue however, but since its talked about on here so much, i wonder if its just a matter of time before it starts to blue smoke.
