I realize that different oil weights and different filters will change the oil pressure. I have not changed my oil weight, but I did change my filter. My question is this: what (on average) pressure should the oil be at when starting up/idling after warmed/running on the highway? With the new filter I have on, I'm running about 107psi on startup, and roughly 87 psi going down the highway at 65mph. My old filter (Fram) had me about 93 psi on startup and about 82 psi at 65mph.
Just a little info: 02 wrx, stage 2, about 15psi at full
I have the Q-horsepower full synthetic oil, 5w30
