Default Oil pressure guage to zero for a moment ONCE

So I get off the highway today and I'm stopped at a light the oil pressure needle goes to the red zone for about 1 second and goes back up check gauges came on and went out.

It doesn't do this again driving 100 miles today it has NEVER done it before.

I read a lot of the old posts about this has anyone had it intermittently?

I'm afraid I did have WAL-MART change the oil!!! It'* got whatever crappy filter they slapped on there.

Well...


first off the oil pressure should be lower at a dead stop... and it is not uncommon for older cars to have their oil pressure gauge drop to zero while stopped...

in my opinion, and with my expirience there is no need to worry about the filter or anything like that...

and i also wouldnt worry too much about wal-mart screwin with you... but just change the oil yourself next time... gives you a great feel for your car and a sense of accomplishment...

but it is nothing to worry about...



correct me if im wrong pontiac gods

I would just check the oil level on the dipstick while your car is off and sitting on a level surface. Like mentioned its normal for the oil pressure to read lower at stops or at a warm idle but in the red is dangerous. Maybe it'* just a faulty ground for your oil pressure sensor that caused that. Please let us know if it happens again.

Did you see your engine RPM when that happened? The engine may have had a low rpm hiccup. It happened to me once a couple of years back.

There may have been some rpm hiccups going on the car idles at only 800rpm.

It seems to be running extremely well, hasn't done it again.

I checked the oil level it'* perfect.

The question I have now is, should I get rid of this car? It'* running perfectly with the help of the club!

I could get a good price for it at this point.

How hard did you stop for the light?

If you jammed on the binders, it'* not uncommon for all the oil to run away from everything for a split second, because all the oils way up in the front of the pan.

I did that in my 95 SSEi quite a few times.
