ABSTRACT:
The sharp end of this tool, fitted with an ordinary oil filter socket is centered against the bottom of an installed vehicular oil filter. Using an ordinary socket wrench attached to the other end of this tool, as a handle, the sharp end is pushed through the thin sheetmetal housing and interior partition of the oil filter. Once this tool has punctured the two sheetmetal surfaces, friction between: the tool and the two sheetmetal surfaces; and the ordinary oil filter socket and the exterior of the oil filter, holds the tool suspended from the oil filter. Once punctured, the oil filter drains through the hollow interior of this tool to the low end, where the flow is checked by a simple valve. To drain the oil filter and the tool, the valve is simply opened and the contents flow into a suitable container. After the flow has stopped: the valve is closed (to avoid drips); an ordinary socket wrench reattached to the tool; and the oil filter is removed in the customary fashion, less oil streaming down your arm.
