I am unable to get my oil filter off ! It is a Baldwin and was installed apprx 2k miles ago. I've used a rubber strap type wrench and a standard metal band-style oil filter wrench--and they dented the side of the filter instead of turning it. It just won't budge. Since the filter is smooth, I can't use one of those end wrenches which allows the use of a ratchet handle. Any suggestions re: other wrenches/ techniques for getting this sucker off ? I'm concerned about the filter totally collapsing if I keep trying with my wrenches . It's very cold where I am--would heating it up a bit with a small electric heater help? What do think about those pump-plier type filter wrenches?
