The sending unit could be bad. Does it sound normal? Maybe the filter you put on failed somehow and is blocking oil. That would be a easy thing to replace first.

Change the filter and pour out the oil from the filter to check for metal shavings. If the oil looks normal it could be a bad sending unit or a bad gauge. I had the fuel gauge on my 97 Taurus sho go bad.

You need to find out if there is oil pressure or not first. This is the problem with the stock gauge, it doesn't tell you anything other than if you have 6+ psi or not. It is literally an on/off switch.

However, if your pump has failed and there is no pressure, no you can't use the car like that. You'll blow up your motor running it with no oil pressure.

Replace the sending unit and see what it does. That is a cheap/easy troubleshooting step. Best practice is to have an aftermarket gauge though... the stock cluster stuff is called "idiot gauges" or "idiot lights" for a reason. They are not accurate at all really.

I see this happen on cars in the winter that have used thick oil.
What oil did you use, where do you live?
If you restart the car 20 minutes after you have driven it, does the light stay off since the oil is warmed up and moving?
Does the car still run fine?

What grade oil did you put in ???????????????

I have heard of this problem when people try to use 20W-50 in these engines.
I hope you used 5W-20 like the book say's.

I would think as long as the pressure goes up you will be fine.

Oil pressure usually drops down at idle anyway. As long as it goes up when the engine accelerates and stays up while driving I don't think you have a problem.
If the car overheats, Then you have a problem but I don't think this is going to happen.

I'm pretty sure you should be using 5W-30 in your car. 10W-30 is slowing down the initial pressure when you start it up. It won't really hurt anything but you need to go back to the five weight as soon as you can.

I live in Florida where it stays hot and use 5W-20 year around.

Yes

When it is hot out you will see the pressure drop at idle, then when you rev it up a little the pressure will go up. My 2012 does the same thing.
If the needle on the Gage goes all the way down you may need to replace the sending unit. They are cheap and easy to change. I'm sure your is not dropping all the way down just at idle.

If you really have no oil pressure your engine would be making a hell of a racket. If its not, then id put a new oil sending unit in cant be more than 20$ and if that didn't fix it get a manual one and hook it up to see if your gauge is bad and if all that fails then id drain the oil through a paint filter and see if there is any metal shavings. If not then go buy the cheapest oil run some engine oil cleaner through it for a couple days drain the oil and fill it up again with the cheap stuff and if that doesn't fix it then id do oil pump

A manual oil pressure gauge that is. You can get them at many auto part stores for cheap. I know we sell them at autozone for around 25$

This happened to me. My gauge went up and down constantly. It was the gauge itself malfunctioning. There was oil pressure and I replaced the sending unit twice.

Eventually the whole gauge cluster stopped working and I had to replace it. Now the oil pressure gauge moves all the way over to the right. It's weird.

No problem there

Just wipe off the oil.
Screw in the new sender.
Hook up the wire
Wipe around the sender if any oil
DONE.

Ronnie

PS: I had a 1998 Corvette and the oil sending unit was under the intake manifold. It was a freakin nightmare to replace when it went bad. One of GM's better ideas DUH!!!!!
