What do you mean by more mainstream oils? You don't know what type of oil I use. which is BTW castrol 20-50. Is that not mainstream?
And what do you mean by "masking some problem"? What is being masked by using BMW recommended oil? I don't understand your statements or your logic.
Please help me out here. I guess you are suggesting in some way or form through your statement that you use synthetic so I must also do so? Is that what you are getting at?
