What motor oil do you suggest?

Hey All! Once Again I seek advice.... What oil do you run in your motor? I am kinda interested in the 15-40 Delvac oil. For what reason do you run a diesel oil in a gas motor? Only thing I can think of is the Zinc content. I'm in Florida, so startup in not a problem. Just need something that's err... cushioning 360/904 Street/Strip Combo. Thanks for the thought's :thumbup:
