I always clean the gasket surface, then dip my finger in the cap from a new jug of oil and wipe it around the gasket surface. tighten until the gasket makes contact, then hand tighten 3/4 turn. They always come off easy with a filter base tool, or a filter band wrench. Only twice have I needed the filter pliers, and only a couple times have I had to use a chisel. One of those on my brand new 85 C20, the other was the above pictured Baldwin from my Alison trans.
