is this correct? i have autometer guage for my oil, and when warming up its around 65psi. when hot its around 15psi. when driving it goes up to 50psi, well certain rpms and all, but it does climb with rpms. i just got my s70 turbo on, and full 3in exhaust/SV, and stainless oil/water lines. im running mobil 1 full synthetic 10w/30, is this too light of oil? or is 15psi warm ok? it just seems like thats low. but i seen on here chrysler calls for no less than 4psi. am i ok? or.... not?
