Oil Filter Alert - FYI

Oil Filter Alert - FYI
Just bought a set of Mazda tech bulletins from early 80s and an interesting factoid popped up:
Anyone using the OEM mazda filter is warned NOT to drain the existing filter by punching a hole in the TOP CENTER of the filter, prior to removal!!
Apparently the relief valve (diverts oil in case filter gets plugged) is a DISK right under the center top and can be (not always) knocked loose to fall into the oil channel if top of filter punched with (eg) screwdriver.
It IS OK to punch top SIDES of filter tho - sez the Bulletin - just not dead center.
Thought I'd pass that on...

I only stabed a filter once to try and get the ****** off. I never had any issues with messes with the 7 as I did with the rest of my cars that had a filter on the bottom. I just crack it but don't remove it drop the oil from the engine and then pull the filter. I don't have a mazda filter though.
Is it a mazda filter only thing?
