This may be an old subject, but new to me! I've read all the supposed horror stories about changing the filter element in the cannister-type oil filter assembly. Is it really that tough?? Do I simply need to buy a removal device to unscrew the filter cap, then simply remove and replace the element? Or are there some other devices I need, some other procedures to take. I haven't found any good web sites that deal with oil filter changes. Anyone, please comment. Thanks.
