1. An oil filter socket wrench with built-in oil spillage cup for loosening and removing a spin-on engine oil filter and for containing oil spillage comprising:

  • a circular base having an upper surface and a lower surface;

    a first substantially cylindrical member having an upper portion, a lower portion, an inner surface, and an outer surface;

    said upper surface of said circular base affixed to said lower portion of said first substantially cylindrical member;

    a second substantially cylindrical member having a substantially larger diameter than said first substantially cylindrical member and having an upper portion, a lower portion, an inner surface, and an outer surface;

    an intermediate member securing the upper portion of the outer surface of said first substantially cylindrical member to the lower portion of the inner surface of said second substantially cylindrical member, wherein said first and said second substantially cylindrical members are concentric;

    said circular base, said first and said second substantially cylindrical members, and said intermediate member forming a unified integral cup impermeable to engine oil for the purpose of containing oil spillage;

    angled facets positioned about the inner surface of the lower portion of said first substantially cylindrical member for the purpose of engaging corresponding angled facets of an oil filter, wherein torque applied to the socket wrench is transmitted to an oil filter for the purpose of loosening and removing an oil filter;

    protuberances positioned about the inner surface of said second substantially cylindrical member and extending radially inward to terminate in loose contact with an oil filter positioned within said socket wrench, wherein said protuberances are capable of providing alignment of said socket wrench about an oil filter;

    a gap between the inner surface of said second substantially cylindrical member and an oil filter when the socket wrench is positioned about an oil filter, wherein said gap is of sufficient volume to contain oil spillage associated with loosening and removing an oil filter.
