Abstract
A tool for use when changing the oil filter of an engine and refilling or putting oil into the engine. The tool is generally funnel shaped, having an internal surface which frictionally engages the oil filter after its seal has been broken. The tool has an extended portion of a greater diameter than the filter to catch any oil which escapes as the filter is removed. The escaping oil is channeled to the outlet portion of the funnel, to which a plastic tubing may be positioned to remove the escaping oil. The tool may then be used as a funnel to fill the engine and complete the oil changing process.
