What's y'all's oil pressure readings on 5.7 vortec?

[Kyle97GMC]

Yeah I do I like hearing my straight pipes from stops. But I have never seen it really go past 45????

 

[Kyle97GMC]

I just checked it out on my way home and at about 4200 rpm it just went past 40 psi... Should this worry me

What does your read when it's cold? When driving mines between 40-45...I'd be worried if you have much less then 20 at idle

 

[Kyle97GMC]

Its about 20 when idle and when driving it never gets passed about 45 no matter the rpm. it is pretty cold here at night right now and thats what it did last night

It really just depends on how the engine is maintained. Mine has run Mobil 1 in the engine since it had 22 miles, and I can tell. Generally, when cold...

50-60 idle, 70-80 while driving.

When hot...

35-50 when around idle speed, and usually 60-65 going down the road.

mine runs about 40 when idle and when driving runs about 60

Well my grandfather was original owner of my truck he always serviced the truck regularly 3,000 miles and drive it on mostly highway, also I have ran valvoline full synthetic since I bought it, I run it 5k miles, and never add a drop, that's with living in mountains and towing as well it's stays nice and clean looking on the stick as well. 202,0000 miles now I have gave it hell tho.

 

[Kyle97GMC]

Yeah im a little worried now. I maintain it good but I have put it through hell and back

Is it a little low, ya maybe. It could be you're pressure sensor or gauge going bad though. You could try a mechanical gauge just to double check the factory one.

Imo if the engine runs good an isn't making any noise then I wouldn't worry a whole lot. I would be a little easier on it though.....

i peg 80 in mine while driving cold. When warmed up about 70 driving. idle 20ish.
