Hello guys, I have a question here is my truck 2003 Tacoma V6. Now my question is what oil would you recommend me. Currently I'm using RP 5w30 as motor oil. I was thinking to switching to pennzoil ultra. My truck valvetrain noise was louder with Mobil 1 with RP I have no noise. Anyone used pennzoil ultra on Tacoma can give me feedback on Pennzoil Ultra. Thanks in advance.
