5 or 10w30 in the summer?

I use 10w30 year-round in Miami.

LOL...you guys in Miami don't have to put up with b**l freezing weather in January but you do have the super warm in July/August. (Man, I miss Florida)
I found 10w Mobil 1 still works great all year up here in the freezing North too.
Have used it for years in all my Isuzus, with no problems at all.
