I've been running 10w30 dino oil in my Miata (located in Southern California)
and will be installing a BEGI I turbo system from DA in the next few weeks.

I'm sticking with dino oil (don't want to experience the leaking seal problem 
some have had switching to synthetic with an "experienced" engine) - but 
what weight oil should I be running with the new turbo?  Continue using 10w30, or
move to 10w40 or 20w50?
