I've used full synthetic 5W20 in my 5.7L "C" for about 18 oil changes over 65K miles, and will be doing yet another on Black Friday to prepare for winter. Zero issues with DTC p0520.

It ain't the oil, it's the switch.

I recently got the code 0520, so I replaced the switch. It was indeed a pita. My question is, the check engine light continues to burn and now my mds doesn't engage. Any thoughts? Before changing the sensor it was reading 99 psi. Now, it's 56-57 cruising at about 60mph.

Thanks,
Denny
