What grade oil to use for my Vortech for oil change.

I'm going full synthetic of course.
I just need to know what weight to use.
Normally the G35s take 5w 30.
I was told 10w 30 Synthetic for FI engines.
Just wanted to reconfirm because my oil change is due today.

By the way, I'm from Boston, MA. (I guess temperature has some things to do with what weight oil to use as well...)

I would recommend 10w30 for the warmer months and go back to 5w30 when it stays cold.
