If this were advertised as a self draining oil pan, I would have rated it 5 stars!  We're not talking about a leak that is just a few drips, this thing leaks so much that it could empty itself in an hour.  I bought this at Wally World and returned it for a refund while it was still filled with oil leaking out of the small cap.  Just like everyone else has stated, it's garbage and not worth the used oil you dump in it.
