Apparatus for changing oil in an engine that has a main oil pump for circulating oil through an oil filter attached to a filter head of the engine. The apparatus preferably includes an adapter ring that has at least one passage for receiving oil from the filter head and at least one auxiliary port that communicates with at least one passage. The invention includes a coupler for attaching the adapter ring to the filter head such that a fluid-tight seal is achieved between the adapter ring and the filter head. The coupler permits the adapter ring to be selectively indexable relative to the filter head about a first axis. The coupler further enables the oil filter to be removably attached thereto such that a fluid-tight seal is achieved between the oil filter and the adapter ring. A coupling assembly is attached to each auxiliary port for selectively blocking the port and permitting the port to be opened upon attachment of a first conduit thereto. Various conduit arrangements may be attached to the auxiliary ports to facilitate rapid changing of engine oil. Sensors may also be attached to the auxiliary ports for monitoring conditions within the engine.
