I have a couple of questions about Castrol TWS and Castrol Edge Professional 10W-60.
I have a bottle of BMW branded TWS, dated 17.1.05. It was in the trunk of my 2002 M3 from when I purchased it. Is this oil still usable or is it better to put it on the shelf?
Also, I'm wondering if anyone has a blackstone test report that confirms if the "recommended for BMW" non-BMW branded Castrol Edge Professional 10W-60 is the same as the BMW branded Castrol Edge Professional 10W-60.
