But I didn't change the o-rings last time I did an oil change. I'll make sure to do that.

The last time I saw an STP Oil Filter it was made in India (it was the same as the Indian mad Purolator oil filter). I cut one apart and they are poorly made. I would acquire a better filter.
I have never had mine apart but down there where the 2 O-rings are there is a spring-loaded valve. One of our members said that he had a low oil pressure issue, and he dissembled the valve and fond some of the cotton filter media that is in the top portion of the oil filters stuck in the valve.
