so you are running Mobil 1 ? if your car is still using oil after the PVC change it might not hurt to try a different oil. i used to run mobil 1 in everything Ive ever owned....... till i bought a subie.I have never had a problem with Mobil 1.
You say this, but you also say you are having an oil consumption problem...........I have never had a problem with Mobil 1.
