Olive oil has a very low smoke point and burns easily, but I've seen tons of BBQ gurus advocate seasoning steaks (along with other meats) with olive oil, salt and pepper. If you're applying crazy high-heat to those steaks, the oil is going to burn. It won't taste good, and it won't be good for you. Oils like Avocado or Macadamia Nut have a much higher smoke point and seem like a far better choice, so why do so many people who seem so knowledgeable insist on using olive oil? Genuinely curious.
