I need a Favor ASAP...

You should be at 30-32 at idle and running around 40-42 at cruising speed. I did a similar build to yours but more extreme and I have the Aeroforce Interceptor gauges installed as well and my 4 pack gauges seem to be accurate with the Interceptors.

Maybe try another dealer? Worth a shot,I'd tell them the situation and what the other dealer said and see if they agree that it isn't an issue...can't hurt to ask. But the text above from GM does say it could temporarily stick open...so if you temporarily lost all oil pressure it could be hard to duplicate.....

I had already decided to take it to another dealer as you stated. Maybe I'll have better luck next time.

Not sure how close you are but maybe try Hendrick in Cary...haven't dealt with the service dept but sales dept was TOP NOTCH! They seem very performance oriented...which can't hurt.

Find the oil pressure sensor remove it and install a mechanical gauge. I can't tell you how many times people have brought in cars with "low oil pressure" on a gauge but has proper oil pressure on a mechanical gauge. IIFC the 4 pack gauges is just plug and play so it is reading off something in the ECU so it can be reading incorrectly even though you have proper pressure. Hook it up to a mechanical gauge before condemning your oil pump.

I know what you mean...alot of modern gauges read a set value between x value and x value...for instance many stock oil pressure guages will read "normal" until the pressure is down to just a few PSI..I call these idiot gauges..The guages on the 4 pack is not "idiot" guages...they reads real time from the sensors...just as good as a mech guage. That is not to say he couldn't have a bad guage or sending unit though..
Now the coolant temp guage in the cluster..that is an idiot guage...

The dealership actually did hook up a mechanical gauge and it confirmed the readings on the 4-pack gauge.

Here are my thoughts. If it was really that low, I would be getting a check oil light at 20psi or lower). Mine is reading around 17 at idle on the 4-pack gauge. I am guessing that it is inherently unaccurate anyway.

This does concern me, but I think I need to get it plugged into HP tuners or something similar and have a real readout given ASAP.

Thanks for the help, and I would appreciate any thoughts you folks would have.

This thread is freaking me out. I read this post the other day, and didn't think much of it untill I was sitting at a drive thru the other day and glanced at my gauges. At Idle I was sitting at around 17 (slightly above the tick mark between zero and 30). So how low is too low, and what is normal for a fully warmed up to temp engine at idle? (LS3)

Are these cold pressures you guys are reading? I dont even know if they change much from cold to hot, I have never paid that much attention. Does it sound like I have a problem like the TSB someone posted in this thread? I can see my service department being like the one who told the guy that everything is normal since I am not getting a low pressure light come on.

A general "Rule of Thumb" for oil pressure is 10 psi per 1000 rpm. So at 3000 RPM = 30 PSI. Seems low but I've seen engines running these low pressures and do fine. Back when I drove trucks, idle oil pressures were under 10 psi.

I agree,depends also on how the engine is set up...as in the above case where the dealer told him it was "in spec"...it probably is..but I think there is more concern with "abnormal" pressures(ie pressures lower than the majority are seeing) due to the bulletin. Guys with less oil pressure than the majority have reported are wondering if the relief valve is sticking partially open and if/when it will stick open enough to cause an issue...it would suck to cause damage or be stuck on the side of the road due to an issue that could easily be prevented. But honestly I wouldn't sweat it too much as long as you have plenty of warranty left...if the dealer denies there is a problem you might just have to wait until it is undeniable.
I think mine idles around 30 warmed up,but i'll double check today.

Sorry I can't help, I don't have the aux guages on my 1SS. However, if you need a stock 1SS to compare numbers with, let me know. I live fairly close to you.

Ok checked mine on the way home....oil temp a little below 200* leaning over looking straight on at the guage it idles about a needle width below 30. At 2000 about a needle or 2 widths below the line between 30 and 70.

Ok. Thanks. Maybe it isn't as big of a deal then, it just worried me when I saw my pressure, then went back and read this thread again where someone had posted that TSB. There may not be that big of a difference in our actual pressures. I read once that your oil pressure increases as your oil gets dirtier leading up to a change. Not sure how new your oil is but I just changed mine about 200 miles ago.

As someone else mentioned I would also question the accuracy of the 4 pack oil pressure guage and sensor that it is connected to. It isn't exactly meant to be a precision instrument.
