ABSTRACT:
An oil drain plug wrench adapter is disclosed comprising a disk having a disk upper surface and a disk lower surface, a square aperture sized to fit a standard socket wrench male drive extending through said disk and centrally located on said disk, and a pair of post holders extending perpendicularly from said disk lower surface, said post holders having post holder bores spaced apart relative to each other and sized so as to allow the posts of a standard two post oil drain plug to fit into them. In operation, a socket wrench male drive is inserted into the square aperture, the posts are inserted into the post holder bores and the oil drain plug is turned using the socket wrench. If necessary, an extender having an extender female end and an extender male end may be interposed between the socket wrench and the oil drain plug wrench adapter by inserting the socket wrench male drive into the extender female end and the extender male end into the square aperture.
