Oil pressure reading
I'd be obliged for a pointer please; I'm unaware exactly what the oil-pressure gauge should read (10K miles 997 C2S) once the oil is at operating-temp.
Mine sits at "2"-ish (on the gauge) at idle and rises to 5 (the max) from 3,000revs where it stays as long as revs are high. Varies, obviously, between idle and 3,000.
So cruising at 75-80mph it's sitting at "5" all the time.
Is this correct? Seems strange to have a gauge which maxes out under normal conditions. Ought I to be concerned?
I tried searching the posts for some prior information but seem to be dominated by 928 models.

Typical and normal Oil Gauge readings:
Cold engine at any speed = 5 bar
Warm engine idle = 2 bar
Warm engine above 3,000 rpm = 4 bar+
Idle pressure may be lower if you are running Mobil Water in the engine.

Thank you all.
We had a lot of snow here today - unusual and my first since owning this car. I discovered quite quickly the formula which reads:
(355bhp) + (2" snow) + (RWD) = interesting getting-to-work experience!

That will happen running Mobil Water through the engine.

OTHO, picking up a set of take-off lobster forks for fitting the SnowSports has changed my opinion of my summer Sport Designs... I actually think I like the car better with the 5-spokes?!? I know, I need something to worry about... <g>

These much-maligned 'lobster claws' are just fine for me. I first saw them a couple of years back and my impression was guarded, I guess. But I came to like them a lot - even before getting a car was on the agenda. Also, mods are great but there's something nice about a car looking as it's supposed to.

The lobsters don't do it for me if I just look at the wheel, but once on the car, they really look good.
It's just a good fit with the 997, and good thing 'cause it will save some money for me on upgrading.

I luv my lobsters, the design provides a great balance with the 997 body style. Additionally, cleaning the inside wheel area is made easy because of the large openings. The lobsters receive great comments and for me it was an additional option on the non-S. Cool wheels!

FWIW, a So Cal team I race with runs 15-50 Mobile One in both their Cup cars and their 04' RSR(all spec'd at 0-40). They got 60 hours on the RSR before they sent it to PMS, and it still had great leakdown numbers and compression. They refreshed it anyway. Their Cups have similar hours and aren't close to needing a rebuild.
