So I'm having issues with my wrx in the way of oil pressure. My motor is a brand new ej22 with 1500 miles on it... The pressure is supposed to sit at 14-12 psi at an idle. For the most part thats where mine sits. But when I'm doing some sporty driving, it drops to like 10 psi. But the oil has to be nice and hot.. I feel as though the oil is breaking down prematurely I changed it like1000 miles ago and I used 5w30 and was informed that was a little thin.. Any ideas? Or do I even have a problem at all?
