Hey guys whats going on.

My 03 Cobra is right around 60,000 miles and I'm currently running Mobil One Synthetic 5w30. The car doesn't have any Valve Train Noise but a very light Tick (Most likely the deaded head tick). You can't hear it until you bury your ear right near the drivers side head.

Cars been running very Strong for the Last 18,000 Miles. Not pulley'd yet but will be slipping on a 2.8" next month

But just out of curiosity, would you guys recommend going back to the 5w20 grade? Will thinner help circulate it better?

or should I just stick the 5w30. I don't know what the prior owner (Ages ago) use to put in but I know when I bought the car I just went straight to Mobil One 5w30

:shrug:
