I recognize that BMW's LL17FE+ oil standard is not one that every manufacturer is trying to meet, and that it presumably requires some fancy footwork in the lab to conform, but I am nonetheless shocked and appalled to see Pentosin's offering selling for $26 a quart on Amazon. I was already squeezed by paying between $50 and $60 for five quarts of Liqui-Moly. Will we ever see this standard met by Quaker State at less than $35 for five quarts? Will we ever be able to have a decent discussion about whose LL17FE+ offering is best, or are we destined to by as cheaply as we can, or defy BMW's guidance for their most ubiquitous new engines and simply go for a cheaper 0W20 oil.
