Hi Everyone!
I just ran into an issue with my 07 LT. Out of the blue, my oil pressure reading dropped to 0 and I got the 'Low Oil Pressure' and 'Stop Engine' messages. I got scared and pulled over; checked the oil level and it was just a touch below halfway on the cross-hatched area of the dipstick. No leaks anywhere.
I start it back up and the gauge jumps back to 40ish psi like normal. A little while later it does it again, gauge drops back to 0. I listen and there is no valve clatter, no loss of power. No indication of any problem other than the oil pressure gauge. The next day it dropped to 0 again while I was in a drive-thru. That is when I noticed it would drop to 0 at idle (about 600 rpm). If I ran it to about 900-1000 rpm, the pressure would jump right back up to normal. Let it go back down to idle and it drops to 0, blip the throttle and right back up to normal.
I have driven several vehicles with low or no oil pressure and I know some of the readily identifiable symptoms. I am experiencing nothing like I would expect if there was no oil pressure. Is this a sending unit or a gauge issue? Could my oil pressure possibly be as low as the gauge indicates? It has me a little worried.
I look forward to hearing any thoughts, ideas, suggestions, or input. Thank you all for the time and have a great night! Stay safe!

PS: There is a large truck driving by in the beginning. That is not my TB!
