NAPA has oil wrenches that actually fit the bottom of the filter and you use a 1/2 inch bar, it is better to use and extension to reach the filter tool that way you will not peel your knuckles the tool fits the filter snug they are like a shallow bowl, when installing the filter use a little oil to lubricate the filter's gasket and make sure that the old gasket is off with the filter, once the filter is hand tight turn no more that a 1/4 of a turn to tighten either by hand or better with the tool, do not turn more than 1/2 turn.
