OK I have seen this thing before, but I cant find it now. I will try my best to describe what it is. After pouring oil into the engine there is still a fair ammount of oil still in the quart container, so what you do is screw the "empty" quart upside down into a collector. 4 of the emptys are connected upside down into the device and the 5th is under all of them and collects all the left over oil. If I do find out what I am talking about I will post a link, but if you can figure out what the heck I am talking about PLEASE let me know, and hook me up with a link or what-have-you. Thanks
