Just had a warranty oil change on my 440 with a B58. Document says that they used LL-01 and 0W-30. My understand is that they were supposed to use LL-14 and 0W-20. Verified this with another dealer. I live in the northeast, should I be concerned? If so should I demand a fill and flush ASAP

EDIT: when the technician fills the oil, do they use BMW 1qt containers or bulk oil? Trying to see if there is a way to tell which oil they used
