Hello,
Just registered here after finding this topic in a web search.
I see that this topic is rather old, but it is the exact thing I am am having a discussion about with other people.
Bottom line question is this:
Does this oil, QS 10/30 Defy actually qualify as being zinc efficient for daily use in my 1966, totally stock, not driven hard, hot rod?
Thank you
