I've been ignoring the problem and using a lack of an oil filter wrench as an excuse to put if off. I'd ordered one but it never came. Just followed up on it. Turns out the place I ordered from forgot to send it and with a reminder are now sending it. So I'll do the oil change as soon as it arrives.

You recommended using a grip cloth instead but I couldn't figure out what the hell that was no matter how much I googled.
