What should I mix my Biosyn with.......BMW M62

[chefwong]

I've got 6 qts of the Biosyn 5W40 left.
Sump calls for 8.5 qts

BMW M62 in typical Northeast weather zone - oil will probably be run from late march to late november.

What's a good OTC oil you would dump with this oil....
I have plenty of GC lying around but totally open to suggestions to any other oil that is OTC avaiable..

GC or Mobil 0w-40.

Since you already have GC I'd just run that.

Does this mean you did not like the biosyn enough to buy it again?
