Before throwing any kind of food on the grill, make sure to oil the grates to prevent sticking.
This is false. Per Cnet:
Actually, it’s OK to oil the grates if they’re below the smoke point, Blonder says, but if you wait until after that, the oil “cracks, smokes, and caramelizes almost instantly,” which can negatively affect the taste of the meat and even make sticking worse. To be safe, oil the meat, which is cold and will therefore keep it from burning and cracking.
