What's the best device to assist in changing the gear oil?

Well, I just cut a hole in the side of a new jug of Cat Litter, lay it
under the plug, take it out, and let it drain into the litter.You can
manouever the jug out after the plugs back in, with no oil spilled.

Sure you do, dumbass. And you recycle it where?
