  1. The reduction in zinc is why many oil blenders are now relying on moly, titanium, and boron to provide the necessary anti friction and extreme pressure protection that was traditionally provided by zinc.

While zinc is interesting, with modern oils, I have grown more fond of those that have generous amounts of moly and boron in them.
