I have little grip anymore. I always use a cup adapter and a 3/8 socket, I tighten util gasket touches, then go 1/2 turn. My BMW motorcycle the filter is in a recess, and MUST be tightened with a wrench. I often use M1-102 fitlers, and never a drop of leak. I reuse crush washers too. at well over 100K and I know of those over 300K on these filters so something works.
