Well, the dealership had tightened it so tight that my normal socket wrench could not break it. So then I got out my rubber hammer and started trying to knock the wrench in the open position which did not work and then tried hitting it with a small maul. I the got out my torque wrench which is about 18" long thinking it would break it with the added leverage. Still no luck. I even tried a 1 1/2" three foot long PVC pipe to try to break it and it just started to round out the inside of the filter socket. So, finally out of desperation I got out my impact wrench that I use on lug nuts and finally, with that, I got it to loosen! THAT is why I do all my own work if possible!
You should never use a torque wrench to try and loosen a nut, bolt, etc., especially one that's stuck. It could ruin the wrench.
