Giant Channel locks, Giant screwdriver driven through filter, Air chisel on filter base. In that order!

dammmmm....
I had a fuel filter that was stuck on so bad it was destroying the mount. I ended up taking the whole mount off the engine so I could stick it in a vice. drove a 2' long screwdriver through it and breaker bar'd that F'r...

Your lucky. I had a couple oil filters (not mine) I’ve hade to take a chisel to the base at the pad. Always put oil on the rubber seal😎

If you know a medic or a nurse, the blue rubber tourniquets wrapped around it then either hands or a filter wrench. The rubber makes a nonslip surface.

Those chain wrenches that are on vice grips are the solution. Cheap at harbor freight and will get them right off. I've final gotten smarter and never put a filter ON with a wrench. Just my hands

Hammer and chisel, in lip on base of filter.

I haven't used a wrench to put a filter on.....EVER!!! And I always put oil on the gasket. I don't know why this thing was stuck....but it was stuck like a MoFo!!!!

Sometimes I can't get my hand on a filter good enough to trust tightening it by hand so I have to snug it a bit with a filter wrench. A bit too tight is infinitely better than having it come loose!

Heat it up
 

I have a heat gun that is supper hot. I’m sure that would loosened up the oil filter. On my aircraft I use dow 40 in a green tube. It is a clear silicone used on the rubber gasket.

try cracking them loose before you drain the oil. not enough to leak just loose... then warm and drain...
