[Tigers] Best Dino Oil for 260/289/302?

[Thomas Witt]

Rotella WAS purported to have higher zinc content. I'm starting to hear that 
is not the case anymore, but can't confirm.

  I used that and GM - E.O.S. (engine oil supplement) on a 318 I broke in 
recently. I also heard rumors that it is also no longer available. All I can 
say is the cheap flat tappet cam (SSI brand from PAW - I think Chinese) 
still has lobes.
