oil type?

What type of oil do most of you run in your wolvy, Im about to change it for the first time since ive had it.The temps where I live the next few months will get between the 70's and 90 degrees farenheit somedays with high humidity in central North carolina over the summer especially.

I run Castrol 4 Stroke motorcyle oil, 10w-40. I used to run mobile 10w-40, but I found that my machine shifts better with the motorcycle oil when it gets to opterating temp.

I'm trying to get some feedback regarding synthetic oil.

I've always run Honda HP4 in my bikes. Tried other stuff, but that seems to work the best for me.
