If you can, cut the pad out do that then lay plastic down before using the claw. Easier to remove the pad with the Baby oil then to try and suck it back up and through. I would mix up some extreme clean, powerstrike,powermaxx etc (somethign designed to eat oil) and satuarate the area then water calw it while using your solution line to flush the carpet while using the claw. After your done extracting you should put down some Stain Blotter, Diatomaceous earth which will help pull any oil that was left behind.
Good luck and be sure and take pictures and post them
