ABSTRACT:
Method for removing an oil filter from an engine when the filter is to be replaced or removed and apparatus for assisting such oil filter removal. An air valve is positioned on the casing of the oil filter and air is injected into the volume of the oil filter surrounding the internal filter. The air displaces oil in the oil filter. This reduces the quantity of oil in the oil filter and, after the air chuck and compressed air line are removed from the air valve, allows the oil filter to be removed without dripping oil on the floor of the garage or on the operator performing the servicing of the oil filter.
