Default Oil gauge dancing?

I was driving yesterday and noticed my oil gauge was sort of jittering around while I was stopped at idle. Almost like it couldn't decide between 38 psi to 42 psi.
Could this be the oil pressure sending unit dying on me?
I did a recent oil change to a lighter oil, but I doubt that is related.
Any help is appreciated!

Could be the pressure release spring for the oiling system. You could throw a mechanical gauge on it to double check but if you still have pressure and it rises with RPM I would let it eat. Mine did that for a little but but stopped and has been fine. Just see if it goes away with time but if it gets worse it could be the oil pump. Just keep a close eye on it.

try checking ur oil sensor it usually is sitting above where the oil filter is its a black piece that is connecting to wires that controls ur gauge in the car i was changing my oil filter and my hand slipped and hit the sensor and broke it on accident which caused my gauge not to work at all and i went to autozone and got one for like 30 bux try it if it doesnt work return in

FireChickenws6: Thanks for the reply and yeah the psi goes back to normal when accelerating (increases).

camarolover209: I'm pretty sure your sensor is in a different spot because you have the 3.8, but if not, that could be a very real possibility. My filter was being feisty .

Mine does the same thing.. I made a thread with video about it and the consensus was that it was fine.

The LS1 has the sensor behind the intake on the drivers side, different from the V6.

Ya sounds like your sending unit will be going out soon. Not really an un-common problem.

What kind of filter are you running? This happends on a lot of cars if your running a crappy filter such as a Fram. It was doing it on my 3.8 bird then i found out how shitty frams are and went to a delco filter and went away completely.

Alright thanks everybody! I will just wait it out, if all of sudden I'm at 0psi I know it's time to replace the sending unit.

To the guy who mentioned the 3.8 bird, I'm running the Amsoil Ea032...so I don't really think that applies .
