I have new full oil, and the light has come on solid. What are the possibilities or tests I should make? Is it ok to drive it?
thanks

Welcome to Allpar. Is the engine noisy like tapping or clicking? I would not run it or drive it until you can perform an oil pressure test with a mechanical gauge.

Unscrew the oil pressure sender and install the gauge for the test.
Is this a GM 3.1L?
It is possibly a defective sender, but you want to make sure first.

Double check the oil filter itself, especially if the light didn't come on until after the oil change.

The 2.8 and 3.4, IIRC.

Did you do the oil change yourself? Since I haven't worked on one of those in a while, is it possible the sender wire is caught somewhere and grounded? Other than the intake gasket leaks on the earlier ones, I don't recall many problems with these. My son has a 1994 Buick Regal with one and it has well over 200K on it.

The 3.4 in the 90's to early 2000's were notorious for gasket leaks you can't see letting anti-freeze into the oil and totally ruining the engine.

I wonder if the original poster is ever coming back?

Maybe very busy with the holiday and family? The northeast is also very cold with blizzards and travelers advisories this long weekend. I somehow, really want to get outside and rinse the road salt off the cars. :eek:

Could be the wrong grade oil, too thin, maybe.
