oil filters and oil pressure increase ?

I haven't heard of such a thing, I would just put thicker oil in it... Something with -40 or -50 viscosity rating (like a 15W-40 or 20W-50). Just don't use it in the winter time.
Thats what I will have to try..Thanks... I did not see how the filter could change the pressure. But thought I would ask... I fell for it.
