Re: 2012 5.7 L Oil Pressure with Mobile 1
Istarted this thread about 26 months ago, my GC now has 26777 miles, about 1kper month.
SoI thought I’d recheck my oil pressure, and it’s essentially identical to the 1kmiles readings:
idle: 34 psi 34 psi
freeway: 52psi 52 psi
oil temp: 200F 203 F
coolant: 210F 212 F
Outside: 68 F 69 F
The oil was changed at dealer with synthetic, about 3k miles ago. Not sure what kind of synthetic, maybe Pennzoil.
