A combination oil filter and key comprising:
- an oil filter having a casing and a top that both surround a vertical axis;
- at least two tabs rigidly affixed to said casing, each of said tabs having a hole and a tab top, wherein each of said holes surround respective axes that are generally parallel to said vertical axis;
- a key having a handle with at least two posts that are generally parallel to one another and adapted to be received within a respective one of said holes, said handle including a plurality of serrations on a top thereof and a plurality of finger grooves on a bottom thereof, a bridge spaced apart from said handle, wherein said posts are connected together by said bridge and said handle, said handle having a grip space bounded by said bridge and said posts and said handle so that said grip space is adapted to accept the fingers of a human hand and is further adapted so that the palm of the human hand can rest on and contact a plurality of serrations on the handle top;
- and
- wherein said tabs are positioned opposite each other on said casing and said tabs are aligned so that said top of the casing and each of said tab tops are in the same plane.
