Oil Pressure Issues, Incompetent Dealers

Have you gone into the gauge cluster and at different stages of driving checked under the "Oil Pressure" reading that says "low", "normal", etc? Also, have you checked the oil level on the dipstick? I've been reading far too many stories of dealerships overfilling the oil in particular. Another option would be to hook up the car to a mechanical oil pressure gauge if you don't trust your car's electronic readings.

Similar thing happened to me and dealer says it normal

90PSI is normal?

I would believe that if not for the past 10K miles it was running 55/65 PSI

I'm assuming you have a PP model by the way you describe the gauges. If both the oil pressure gauge and vacuum gauge are acting up strangely at the same time, I'd 1st suspect some kind of electrical gauge control problem. If the vacuum gauge was actually reading correctly, the engine wouldn't be running very well at all based on the gauge readings.

But definitely have it checked out by the dealer ASAP to make sure it's not a mechanical cause.

What weight oil are you running?

My cold start up pressure is 90psi, too. I have 9k miles on my car. I run Pennzoil Ultimate Platinum 0W-40.

After 15 minutes, idle pressure is 30psi. When I ran 5W-20, warm idle was 20psi.

Any 'whine' sound is not normal. Hopefully nothing major once it gets back in.

Same thing here my oil pressure is usually pegged at 100 when engine is cold. Once warm usually stays around 80 overall much higher oil pressure than any other car I've owned. But haven't had any issues with engine (10,300 miles) but I'm currently getting a new transmission installed.

A manual pressure check with a mechanical guage is pretty easy on these cars and would give you a quick answer if it's electrical or base engine issue.

The oil PSI gauge has ALWAYS sat between 60/65 at normal revs.

Oh yea disregard my last comment about it being normal. After about 20 minutes my psi is 25 -35 or so.

You said the car had been idling for ~20 min. If it was just idling, then the oil temperature still isn't to full operating temperature (~200 deg F). Need to go drive it some to get the oil to full temp. Check the oil temperature gauge in the information display to see if it's in the center of the green zone, which is around 210 deg F.

From what I say on the video, it looks like the gauges are responding in the correct direction when you give some revs.

You had mentioned the vacuum gauge was pegged all the way to the right when you first noticed this going on. I don't see that behavior in the video.

The 2nd thing i notice is the VAC guage is either pegged left or right except at idle. I give a little gas and it pegs to the right, let off the gas it pegs to the left.

^^^ There is no way the vacuum gauge is reading correct vacuum in that video. Only time the vacuum would be close to zero is at wide open throttle. You were just cracking the throttle open. Pointing towards an electrical control issue with the gauges IMO.

PP have the digital gauges to compare with the physical gauges?
