Question Oil Pressure

I have a 2019 GT3 and the oil pressure runs above the red line. At about 4000rpm indicates 67 psi with normal oil temp. Any body else see the oil pressure above the red line.

Not as far as i remember (not driving it anymore). as far as i remember it was on the high side but never up to the red zone

Normal to be between 4 and 5 Bar on the analog gauge. 67 psi is only 4.6 Bar (normal). If it was truly above red zone, it would have to be over 73 psi.

If you are seeing 67 psi on the digital gauge while the analog gauge is over 5 Bar, then you have a gauge problem.

Here is the gauge in bottom left (no red zone, but stops at 5 Bar (73 psi):



The oil temp and pressure gauges are normal in picture above at idle - pressure increases with rpm until it should stop somewhat below 5 Bar on the analog gauge.

Maybe you were confused and thought the analog gauge was PSI (divided by 10)? Top of gauge is sometimes thought to mean 50 psi, but it means 5 Bar (73 psi)

I had the same concern - from what I remember somebody wrote previously that the digital gauge on the GT3 is the same scale as the normal 911s so the gauge always seems like it is running right up to the red line, even under normal use.
I just go by the analogue gauge now - that digital one causes alarm for no reason - seems an oversight porsche should have addressed with the GT3.

Where is Red zone on digital gauge?

I do think it’s weird that all the gauges for North American cars have Standard (rather than Metric) figures (including PSI for tire pressure), but they don’t use PSI on the analog oil pressure gauge.

I think you guys are correct. I was only looking at the digital gage. The 2015 GT3 oil pressure never got any where near the red line. Too cold for the tires now. When it warms up I will compare the analog and digital. Thanks

One more thought Why would they put a red line on the digital gage and not on the analog gage. In my life a red line was always a red line. Exceed it you break something.

Pardon the blurry cam - hard to take pics and drive - but you can see from this one that even at 3k rpm in 2nd gear the digital gauge is almost pinned to the "red line".

Yes but 61 PSI is still only 4.2 bar.

Its safe.

I can see its on the redline but as posted above, anything 72PSI + would be too high

I've heard that Porsche never corrected the digital oil pressure gauge for the .2 GT3s, so it always looks "red line" where in fact, it is "normal."

DrKid that is exactly what my gage is doing. PSI = pounds per square inch for that gage and BAR for the analogue gage. I DO like the count down for the oil quantity. Don't like the quantity gage. No bars. I used to know exactly how many oz of oil to ad to fill one bar. Not complaining just observing One more thing then I will temporally go away. Dunlop tires really spin on grass. Don't ask

I wouldn't worry about that. Being up to redline is fine - just not into the red (which hopefully the gauge doesn't display at only 67 psi). I don't display the digital oil pressure on my TFT display, as it's not of any great concern to me with the analog one visible - I think I have Oil Temp (yes this is redundant but very important), Compass Heading, Elevation (I live in Colorado), and Battery voltage.

This has been covered and is more than likely normal, and that digital gauge will even go well into the red zone. The general consensus is this is the same software used in a regular 991. The disappointing thing is, it should be something Porsche should have the dealers change with a simple software update via OBD for the GT cars.
