what i do is to empty the one bottle, and then start another one; THEN
i take the last-used bottle and save it ... and put the next-emptied
bottle on top of it to drain. so bottle-1 becomes the drain-into for
bottle-2, bottle-3,and so on. that lets me drain about as much out of
most of the bottles as i can.

i've seen a really neat thing that i keep threatening to get ... ;)

it's a small rack that allows five or six oil bottles to be up-ended
and drain into another bottle.
so every oil change, you drain ALL the oil out of the bottles you just
used, into another bottle.
eventually, you re-use the drained oil (in the collection bottle).
waste not, want not. :)

i thought i'd seen it at www.griots.com but can't find it on their web
page now.
doing google for "oil bottle drain", i found one at
http://www.bob2000.com/  for $10.99 plus shipping.

a clever creative person could make something up like that for
themselves. ;)
maybe out of some leftover pvc piping?
