I see. I'm using an oil drain pan I got from Wal-Mart years ago and it's still working just fine. Being as I'm something of a klutz, I do appreciate the fact that the chance of spills is greatly reduced as the used oil is contained inside the sealed Wal-Mart drain pan and I can take it right to the Recycling Center and empty it without first having to transfer the oil into another container. At this very moment I can visualize that process ending quite badly.
So, I think I'll stick with the plywood and the Wal-Mart drain pan but I do appreciate the information, BikerKapa. Thanks.
