Default Oil pressure increase for no reason

does anybody have any idea why my oil might increase for no reason. I use 5W30 mobile 1 fully syn. 2001 T/A with stock internals and about half way through oil changes. My pressure is about 40 at idle and 60 at wot, but now its closer to 60 at idle and around 70 - 75 at wot. Any idea's?

never complained about having good oil pressure. I have an almost 80k mile TA and have consistant 60 at idle and higher at WOT, very happy to say the least.

I use the mobil 1 15000 oil, and filter, changed about 4k ago.

The sending unit could be bad too.
