I did my first oil change recently and stumbled across a way to hold the filter while I prefilled it. The plastic container from a large (16 oz. ) container of marshmallow Fluff is about the perfect size to hold the filter and catch any drips. Standing the filter in the container let me do other stuff while the filter soaked up the oil.
By the way - the recipe on the back of the container makes great fudge!
