I had no idea that SM oils had reduced zinc or did i know that zinc was an anit-wear ingredient in oil, until I started reading this board. So naturally, yet something new to worry about (or not).
So, putting aside the issue of zinc and its role in engine wear and not to debate it (in this thread anyway), do I have flat tappet cam motors in the following?
1993 Nissan Sentra 1.6 DOHC
2005 Nissan Fronter 4.0 DOHC
