So today I picked up an STP Extended Performance oil filter not my usual but I did not feel like going to another store looking for my usual Fram Ultra. I noticed the STP has an "O" ring to seal to the engine compared to the Fram that has more of a flat washer type seal. Does it matter? And would you trust the STP "O" ring in real cold environments?
 
I don't think it will be a problem, as it will squash when you tighten it down.
 
Some manufacturers just use different types of seals, nothing unusual here as long as you grabbed the filter that was specified for your application.


On a side note I wouldn't support those Korean made filters with their high price and shoddy machine work. I have posted picture of one cut open and there are burrs where the adbv meets the tapping plate
 
Many of the OEM filters use an o-ring also. The only thing I never liked about using them was that the filter would bottom out on the block and make metal to metal contact. Never had one leak though.

I never liked the can bottoming out on the engine block seat either, especially when it's aluminum. I stopped using filters with that type of base gasket for that reason.

Denso oil filters have a torque-stop feature which lets the filter bottom out on the block. Oil seal deformation is exact without guessing. No over tightening and no leakage.

Yes, at the expense of chewing up the aluminum filter seat on the engine. I've never had a base gasket seal, regardless of the design of the gasket.
 
Camprunner - there is a turning spec for each filter. If you lube the gasket or o-ring with oil and tighten to the turning spec, the filter should not leak. I do not remember ever having one leak when properly tightened.

The turning spec is usually somewhere on the filter or at least on the box the filter comes in.

The turning spec is the amount you turn the filter after the gasket comes in contact with the filter seat.
