So the other day I noticed that my oil pressure has risen a bit. It is winter time here but im in Northern Arizona, and the nights at most get to perhaps in the mid 20's. Now, when I get into my car at night, and its the coldest it is now reading 70 to even 80. After it heats up for a while it then drops back down to the normal operating range 40-60ish. The thing that scares me is this, LAST year it did not do this, now this year it does... So can someone please help me out! Thanks!!
