I use olive oil for just about everything. I keep a small can in my car and one in my kitchen. When I use the one in the kitchen I bring in the one from the car and buy a new can for the car. I'm no expert on the different kinds of oils but seems to me that olive oil keeps better and doesnt get rancid. In my BOB I have a stainless steel flask for olive oil that I fill before each trip out. It holds just enough.
