What oil to use?

[gnats]

Hi Y'all. I'm trying to decide what weight motor oil to use in my 03 Cobra. The manual says 5W-20, but I want to switch to full synthetic. I can't seem to find 5-20 synthetic. What weight do you use? I live in north Florida, where the temperature does reach the mid to high 20's in the "winter". Any help would be appreciated.

I live in Orlando and use German Castrol 0W30.

It doesn't get cold enough to worry about it.
