Problem is dealers will hire anyone with a body and movement(I have had to "train" these so called humans)
I actually change the oil at operating temp like you're supposed to, also drain the filter BEFORE draining the pan so the 1/4 qt in the filter goes down and drain the front sump(I see people not do this, what a shame)
After it drains(I wait till it's just long interval droplets), I fill it with about 7.5 - 8 qts and re-check, and add about 1/2 - 3/4 of the bottle. Always come up about 3/4 of the way on the iDrive or OBC.
I also leave a brand new full qt to my customers in the trunk in case they want to top off at a later time. I actually love my job as BMW Tech and do it with pride, just wish more people took their job's as serious as I do.
