Faulty oil pressure gauge?

ABN45 · Jan 8, 2025

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?

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

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?
