Faulty oil pressure gauge?

[ABN45]

So i have no check engine lights on and the oil pressure seems fine. With regular drive it's under half, but when I get on the gas it goes past half. All seems fine while driving. Doesn't bog down.

first pic is under half with regular driving, 2nd is getting on the gas.

Could it be a faulty gauge?

2012 GMC YUKON SLT/5.3
147 thousand miles.

Thanks yall

looks normal. when the engine is cold I get 40 psi while driving...once warm I get around 35 psi just cruising at slow speeds.. when accelerating it does suppose to increase according to the rpm


Also check your oil level make sure its good. There is also a pickup tube o-ring that can leak and cause the engine to have a hard time sucking oil thru the pickup tube. but usually when this happen youll get really low oil pressure and the oil pressure increases as the engine warms up

What gives you the impression that the gauge is faulty? That's normal behavior and the values are fine. You could use a scanner and view the oil pressure in live data to compare it to the gauge.

Yea, there are some members here that would be glad to have that oil pressure reading on the same year truck.

I'm asking could it be faulty gauges, not they are.

But the concensus seems to be with the replies I have got that there within spec or even better for an older vehicle.

Looks normal to me. It's going to vary with changes in temperature and RPM.

A few days ago I got a Ford Edge as a rental (Ecoboost engine, I suppose?). The only thing it showed on the cluster was speed and fuel level! I was like, "that's it?!" Lot's of other tech stuff tho, LOL.

I did discover that if you put it into "sport" mode, it enabled the tachometer. I then proceeded to pass cars like a mad man

Ya you would put it in sport mode and abuse it, I like it,haha

Oil pressure rises with RPM.. So Totally Normal and within spec.
Drive On !! You've got it better than a lot folks

What do you mean better? I'm curious now.

I'm curious. what were you expecting the oil pressure gauge to display?

No expectations really. I was guessing it might be like my 15 Silverado 2500HD gauge display, no fluctuating, proper oil pressure .

 

[j91z28d1]

your 2015 just sits in on spot on the gauge?


that's instering.

Some owners drive around all day with less oil pressure than you have.

 

[j91z28d1]

so anyone else ever put a scanner on a LT? I know they have a variable displacement pump but I can't imagine they run the same oil pressure at all rpm.

are the new gauges just fancy looking lights or are they actually able to hold high oil pressure at idle? I'm guessing not, cause that would be highly inefficient fuel mileage wise.

but then again the new LT seems to get worse milage in the suv's than the old ls's even with direct injection and 10 speeds.

Lots of people on the forum have had oil pressure issues. Whether it's
from oil pump Oring issues, cam bearings, DOD issues , leaking VLOM's
ETC ETC
Your oil "issue" is NOT an issue at all.... It's working exactly as designed...
SO for having a 10+ year vehicle you are fortunate to have a good one/ one that
has been taken care of.

Ahh ok. I gotcha on why I'm lucky now. Hell i even have a warranty the dealership thru in.

I was reading tho that the 2012 engine/tranny were a good year to have. Just what I read was all.

It does yes. Pressure is always good. No issues.

Use a live data scanner and read the voltages and use this as a scale:

The 2012 probably has a PID that reads oil pressure in psi.

My 2014 does !!! (thru a scanner/hpt/etc)
