Can anyone here share what their typical oil pressure readings are. Mine run about 30 psi and have even seen it as low as about 26. Is this normal? Seems kinda low to me..
Thank you, lots of new stuff to get used to.Yes, that is perfectly normal. My 2014 5.7L Silverado (same engine architecture) runs in the same range. It's the difference in oil galleys and sensor pickup point that makes it so different than what you are used to.
A lot of these do that including mine, I have a feeling they all do it but a lot of people dont have the track dash on and watch the oil pressure gauge when warming up. The oil pressure just jumps around (not RPM related) before it warms up all the way. Not sure why exactly but my guess its the ECM self testing the electronic oil pressure control to make sure it works before its warmed fully.I have another issue - oil pressure fluctuation, Z-51, Dry Sump:
When the car is warming up, after driving a mile or two, I get a momentary rise in oil pressure of up to 15 psi AFTER shifting into the next higher gear. I might go to 2000-2500 rpm in first (at normal acceleration levels, in other traffic), then I shift into second, and right after the clutch engages the oil pressure surges from a few pounds to perhaps over 15 psi (as high as 60 psi a few times) and then drops back down to normal, which is between 35-45 psi at normal lower engine RPM's. Same with the next upshift. It barely does it, if at all, after ten or fifteen miles of driving.
It will do this after driving 15 miles (oil temp rising, maybe at 150-160 degrees), if I park to buy a few items in a store, then come back out and start up again.
The oil level is normal, so the oil shouldn't foam.
The voltage barely fluctuates, if at all, while shifting. Some slight voltage fluctuation is usually present.
I have not been able to make this happen by playing with the throttle, but I haven't tried that hard.
Anyone else have this problem? Or know why this happens?
