Hi, I cannot for the life of me figure out what the small O-ring is for in the oil filter (cartridge style) I purchased.

The large o-ring is obvious.

Attached picture of small o-ring (Also what is the plastic piece for? Throw it in the garbage?)

My guesses: the plastic piece is for some other car. The small o-ring goes somewhere inside, slides down the cylinder with holes in it in the cartridge, or goes in the engine side in a groove?

The cartridge has a bolt in the bottom that you can remove without removing the housing. You pull that bolt off, then shove the top part of that plastic thing into the bolt's place, hard, and the oil is ejected from the filter housing through that spout of the bottom. The O ring goes around the bolt.

If you don't push it in straight enough and with enough force, the oil will go everywhere and your coworker will laugh at you.

My cartridge does not seem to have that bolt, are there more than one style of cartridge?

Also, why would I have a coworker - takes two, to do an oil change
(One woman, bent over, and myself.. that is)

It's the metal part in the middle with the square drive indent.
