  • Patent number: 6945362
    Abstract: An apparatus for capturing oil dripping from the bottom of a vehicle. The apparatus includes a pan that is preferably made of a rigid material such as aluminum or hard plastic. Positioned within the pan is a pad that includes an absorbent layer, which readily absorbs oil, and a barrier layer, through which oil is unlikely to pass. The absorbent layer of the pad faces engine components that could potentially leak oil. The barrier layer faces the pan. The pad is also configured to be positioned within the pan so as to be easily replaceable once the pad becomes saturated with oil.

  • Patent number: 5711402
    Abstract: An apparatus for capturing oil dripping from the bottom of a vehicle. The apparatus includes a pan that is preferably made of a rigid material such as aluminum or hard plastic. Positioned within the pan is a pad that includes absorbent material such as bentonite clay or diatomaceous earth. The pad is segmented into various pockets so that the material remains dispersed over the surface of the pad. The outer skin of the pad is made of a mesh material that allows oil dripping onto the pad to soak through the mesh material into the absorbent material in the pad. The pad is also configured to be positioned within the pan so as to be easily replaceable.
