High oil pressure?
Anyway, I put in about 5.5 quarts of Mobil 1 5w30. At idle the car is fine, running just over 40psi. Before I even reach 6k on the tach, the pressure is nearly 80psi. My pressure has never gone this high when winding out the gears. Why would this oil change cause the pressure to rise so much? Also, is high pressure bad for the engine or do our cars have some sort of blowoff valve if the pressure gets too high?
