Shell Rotella Synthetic 5-40 in all engines I use synthetic in.

I have heard that Shell Rotella oil has a higher zinc content that is better for the engines. I heard this from a pro engine builder near where I live. Is this true?

According to all the info I have read, yes.
Of course they could change the formula tonight and that would be out the window, but as far as I know it's still a great break in and flat tappet oil.
