you drain the oil right into the container you use to take it to the recycling center. Heckuva deal if you ask me!

Where are these "tests"? Who did them? Why we don't ever get to see them? Are they locked in a secret vault somewhere? Or is this topsider mythology?
To the second point - many bottomsiding drain pans have a big screw on lid - designed to be taken directly to the recyle center.
I've gone back to bottomsiding - it now seems easier to me, and cleaner. Topsiding has all these tubes covered with and filled with oil. What a mess. And that's when it works well. Sometimes it doesn't work at all. On the question of which methods get more oil out I'm withholding judgement until the tests are released from the secret vault.
