Yep, the lazy man's oil changer.
bought it from good ole Ken at bimmertools, never ever used the damn thing, its just been sitting here.
now its for sale, $50.

Mine has a small crack in the gauge, that i just saw when taking a picture of it, i guess it cracked during shipment. other than that, its perfect.

here it is on the site.
