I own a 1991 Volvo 240 with 197k miles. I decided to change the oil today (a chore that i've been putting off for a while). I got as far as the part where you put the new oil filter on. The motor mounts on my car are quite worn, and the old oil filter rubbed when I removed it. The new filter absolutly refuses to go on. I managed to strip the threads on the new filter with my futile attempts to install it. I should also point out that the old filter is a Fram, and the new filter is an OEM Mann. When you hold the filters up to each other, it appears that the Mann is slightly larger. I'm aware that the motor mounts will have to be changed, but I was wondering if there was a way to get the filter on without changing them right now, as we are about to take the car on a road trip to Big Bend national park within the next few days. Any advice is appriciated.
