Background: I own a Yamaha XJ6n. This is the first time I'm removing the filter. The last guy who owned this must have screwed it on reaaaal tight.
My oil filter is refusing to come off. This should be an easy removal, but it really isn't. I've bought an oil filter removal tool (something that fits around the oil filter that your wrench can slot into, same as the guy in this video here: https://www.youtube.com/watch?v=Wv6gd7E5o2A) and it's actually slipping off the filter rather than the oil filter loosening. Any ideas? Is penetrating fluid okay to use? It wouldn't contaminate anything?
EDIT: I've already tried the screwdriver & hand-unscrewing route to no avail... this thing is really stuck!
Screw it. It was a £5 removal tool. My sanity is worth marginally more than that. I'll let you guys know what happens, thanks to everyone who took the time to answer thus far.
FINAL EDIT: Managed to get it off by jbwelding the socket to it. Even then - had to try 3 attempts: the first 2 times the epoxy cracked and went first! Mad. I think it was the screwdriver-in-the-side that deformed oil filer enough for the socket not to function properly. A heads up, there. I'll give a "accepted answer" to the guy with the most votes currently...
