Re: Mobil 1 and MDS

cylinder 1 deactivation/intake valve control circuit/open
P-3425 - Powertrain
1 cylinder 4 deactivation/intake valve control circuit/open
cylinder 6 deactivation/intake valve control circuit/open
cylinder 7 deactivation/intake valve control circuit/open
02 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
Could this be caused by this oil? I put 7qts in and it's right on the money. I'm thinking about draining it and switching to Pennzoil ultra since it's Standard MS-6395 and Mobil 1 isn't before taking it in. I've never dealt with MDS so I'm checking to see if anyone knows if this is a sign of it malfunctioning.
I'd read the DipStick threads to be sure. There is some issue with dipsticks being wrong length. But that might only apply to 5.7's that had the oil pan changed to fix the smoking problem.
