2015 silverado oil pressure

Tylerboy · February 25, 2018

is it normal for the oil pressure guage to jump from 40 psi to 45 psi while normal driving?

Colossus · February 25, 2018

yes.

2 stage oil pump. Just wait till it pegs out at 80 when you really put your foot in it.

Wait till you put a scan tool on it and find that 40 psi = 25 psi and 80 psi = 50 psi. Did they think no one would ever check?

What would you normal oil pressure read if cruising at 75 mph? Mine only reads about 30 to 32.

Mine hovers just under 40 at a steady cruise at that speed. Is it accurate? Close enough to keep from blowing it up.

this is why they almost never put these in cars anymore.

people see the needle move and freak out.

Yeah, lots of new cars just have the gauge sit in the middle. Time to bring back idiot lights. Any oil pressure at all is good. The truck will warn you if it gets low. Let it do its thing.

Edit:

I remember my jeep had a idiot light but in gauge form. When started the gauge would move to the middle. And then it would never change. And your engine oil pressure does change as it heats up and depending on engine speed. I guess Jeep was looking for a way to make the vehicle seem more fancy than it was.

Ford has done it for ages with their oil pressure gauges. It's not a pressure transducer.... just a switch. You either have or you don't have lol. GM's gauges actually work and follow what the transducer sends for feedback. My 17's dash gauge reads exactly what the scanner picks up for oil pressure so it's not bad. They can be miles out though too lol.
