I stand by what I said.  I've changed a $h1T load of filters too and I maybe have seen two loose in my lifetime.  And one of those times was on a 4 wheeler which wasn't mine and the gasket from the old filter was still on the base.  Using a wrench would not have helped in that case.  Maybe try this.  Grab and turn the filter with BOTH hands.  Sounds like you need to get better help because after I change filters I at least run whatever it is for a few minutes to make sure nothing leaks.
