I tend to use coconut oil as my pareve cooking fat. But if cooking a meat meal, I dream of using duck fat... one day... for every day coconut oil works quite well and heats without becoming rancid.

My dietician told me to use grapeseed oil to saute stuff, not olive oil. I haven't tried coconut oil yet, though it seems to be all the rage now.
