Can you give me engine size?
(I know the feeling, still snowing here in New England as well!)
Yes- the 5.3L is the most common engine size.
Ok- there are a couple of things that can cause this:
As long as you are not hearing any unusual engine noises (ticking, knocking, etc) then a faulty Oil Pressure sensor can "peg out" the gauge if the internal resistance has failed. This is a fairly common fail item, and cheap and easy enough to replace.
The other thing can cause this is a faulty gauge. If this is the case- the Instrument Panel is under Extended Warranty. If the vehicle has less than 70,000 miles, the updated panel and labor are Free. If the vehicle has over 70,000 miles, the updated panel is Free, however the cost of labor (about an hour) will be your responsibility.
I'd look into the pressure sensor first, then the instrument panel.
If over 70,000 miles the paenl is Free, but you must pay for labor. It will not be listed as a recall, it is an "Extended Warranty". You can bring the "owner's letter" that i sent above, and here is the official GM warranty service bulletin:
