When I was an auto parts store manager in the early 80's through the mid 90's various companies would actually come and teach us about how to use their products. Things like what oil viscosities meant, how to properly gap spark plugs, how to gap and install piston rings, how automotive and HD brake systems worked all kinds of cool stuff.
As was previously stated, unless specifically instructed, oil filters should only be turned 1/2 to 3/4 turn and you should coat the mounting gasket with fresh oil, (they used to say to use your finger, but not so much anymore) and to wipe the mounting surface clean with a towel.
One of the guys who worked on heavy equipment told me to keep an oil filter from coming off without having to over tork it was to coat the mounting gasket with lithium grease. He said it locked it on tight, but being greased made it easy to remove. He knew I was going to try it.
I tried it for the hell of it the next time I changed my oil and it did just that. FFS I had to cut the filter off and use a chisel to remove the base. I told him that I tried it and almost couldn't get the filter off. He just laughed his ass off. Apparently it allows the filter to be overtightened without making it seem too tight, having a higher film strength than motor oil, which compressed the gasket more locking the damn thing on.
That son a a bitch is probably still laughing at me now, if somebody else hasn't killed him.
Also, you have to watch the filters with the nut welded on. They are notorious for not working well. Actually had a friend with a K&N filter pop the nut off and it made a little hole in the filter housing. Best advice is to use a cup style filter wrench that fits the filter you're changing TO REMOVE the filter, never to install it.
