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:

Then Now
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.

Robert

The oil pressure also varies 30 ish to 90+ ish depending on rpm, throttle, crankcase vent/vac, oil age etc...

"synthetic" from a oil change place is not really synthetic.

Just look at amsoil OE versus signature series. Both say synthetic on the label, one says 100% synthetic..!! What the! Oh, and one is 5$/qt, the other 10. Don't get me wrong, they're both good oil, but one is better.
