The oil filter wrench is basically a firm metal strap with a pivoting adjustment hinge and a handle. It's very easy to use, just slip it over the oil filter and pull the handle to loosen it. Once you have it loose, you can use your hand to unscrew it all the way.
*Many oil filter wrenches will only grip the filter to turn in one direction. If yours doesn't seem to be working, flip it over so the handle pulls in the opposite direction.
