Oil filter rant. Why do people crank them down.

I drive hard and have had them back off so I tighten them a little tighter too. I have a nice big pair of channel locks that I have yet to find one that they won't take off.

Come on Brad, now what fun would that be if it came off easy..... I've lost fillings in my teeth grunting trying to unscrewing filters. I have a nice selection of filter wrenches down the street if you ever need one.

I tighten them a bit more than spec too because I've had a few leaks. If there was a simple way of locking them from turning I might be more inclined to leave them looser. It's always amazed me that in many forms of racing it's a requirement to lock wire drain plugs, and take all sorts of other precautions to stop fluid leaks ... yet you can just spin a filter on.

Somewhat related...
When I bought my GT, some grease monkey had put the oil drain plug on with an impact wrench. It was so tight I had to dremel it off. Needless to say, the threads were slightly compromised. I installed a Fumoto valve and now an oil change is so easy.

I hand tighten all mine. I'm no gorilla, but after cranking on them with both hands, they aren't going anywhere on their own. I usually can't get them off by hand a year later. I have no problem if someone wants to put an extra quarter turn with a wrench, as long as they don't require a screwdriver to get off.
The oil drain plug has a torque spec of 37 ft lbs, so it can be somewhat hard to remove with a standard wrench or ratchet.

I tighten them more than they claim you need to. I've had several filters (guaranteed on a Chevy) get loose and leak a couple of thousand miles after installing. I finally asked a head Porsche Training Tech how tight they wanted the filters. He told me that the tell the "little techs" to tighten them as tight as they can get them, by hand. He looked at me and said that I might not want to tighten them quite that tight...but certainly tighter than the "accepted" 3/4 of a turn after the gasket touches.
if you are putting them on with a filter wrench, then maybe you are making a mistake. People used to pay me good money to get them off, and some were beyond interesting.

I guess I have been lucky, never had one back out or leak, and I sure do not get them really tight 3/4 to a full turn.
I do really clean the mating surface though.

A little oil on the seal and tighten by hand always works for me. Still usually requires an oil filter wrench to get off, but just barely.
I remember doing the screw driver and hammer trick on my buddy’s boat. The screw driver just spun around and cut the filter in half. This was after we tried a strap wrench which just collapsed the can. We eventually destroyed/removed the entire filter can using tin snips and needle nose pliers. From there we cut some notches in the flange and used big center punch and hammer to finally spin the remainder off.
We should consider ourselfs lucky the oil filters are out in the open and not buried inside some dirty cramped bilge.
