oil filters and oil pressure increase ?

Haha. I'm not sure honestly my gauge has three dashes a 0 a 40 and a 90! Usually when idling cold it will be right at 40 when its warm it will be right to the left of 40 while driving it's quite a bit to the right of 40. So I'm guess like 30 to 32 during idle and 50 to 55 during driving. That is in a magnum 318 with 260k miles.

Those factory oil pressure gauges on the Magnum vehicles aren't very accurate, confirm with a mechanical oil pressure gauge what the "real" pressure is if you really want to be sure. I think you should be OK though, unless you're getting <10psi at idle you're solid. BTW if you really have 30 psi at hot idle that's damn good for an engine with 260k miles!
