oil filter to remove it

To remove a stuck filter, use a band-type wrench that you've lined with coarse-grit adhesive-back sandpaper (top photo). Or spray adhesive on the back of conventional sandpaper. Better yet, buy a filter wrench with coarse grit welded to the inside of the band (bottom photo).

The general rule for changing out an oil filter is after you hand tighten it, take the oil wrench and give it a quarter turn to tighten it. This way, you can ensure it's not over tightened. If the O-ring is broken, this can cause the filter not to have a proper seal; and cause oil to eventually leak.

it's perfectly safe to use either type of filter with either type of oil. However, if you practice extended drain intervals using synthetic oil, a conventional oil filter may not offer the required service life, meaning you'll have to change it in the middle of the oil drain interval, which is inconvenient.

Over tightening the oil filter can either strip the threading, or break the O-ring. If the O-ring is broken, this can cause the filter not to have a proper seal; and cause oil to eventually leak.
