oil pressure/gauge cluster
 

I just purchased a 09 z71 crew 1500. Inoticed check front passenger tire alrm wason for air, calibrate compass & and wiper fluid. I did all of the above and the alarms are still on. Well today I was driving home and after I passed someone on the road I noticed my oil pressure dropped and alarm read stopengine oil pressurelow. So I immediately pulled over and shut engine off. Checked the oil and it was fine. Go back in and drove it 2 more miles home. It started around 40 but slowly fell to 10 or so. ive heard that the gauge clusters go out pretty regularly or could this be a more serious issue. Im having it towed monday bk to the dealership to have them look at it. I hopeitsjust thecluster.
