I used to use only olive oil when cooking but now I use other oils, too. My new favourite is sesame oil, it has a bit of a burned taste that goes really well with wok dishes. Avocado oil is great for Mexican food and truffel oil goes well with anything, really. Just remember to use it as a spice, a little goes a long way.
I keep my oil bottles in an old measure. This way I don't need to worry about oil marks on the table.
