Since I started doing core, I've been using olive oil for everything. I have sesame oil for recipes, but outside of that, olive has always been the answer.
I was reviewing my WW book this morning and saw that lots of different kinds of oils were core.
I don't know a lot about different oils -- or when you would use one over the other.
Does anyone use different types of core oils? What's good and when do you use it?

I don't know much about oils, but maybe I'll experiment with some of these that you all have mentioned. I love olive oil though, especially for veggies.
