There are a lot of posts but no definitive data on whats the optimal oil temp range for a 997.1 vs 997.2. I hear some people say 180 is their normal highway temp, others say 200, yet others say you should be over 210 to burn off the water. To some 225 is hot, others 240, and track guys say they regulary hit 270. Even at my indy I had 3 different answers depending on which mechanic I talked to.
Why dont we list our oil temps and crowdsource the consensus. Here's mine:
Car: 997.1 3.6
Oil Type: Motul 8100 5W40
Avg Outdoor Temp: Bay Area 65-85F
Oil Pressure:
- @Idle after cold start: 3.5
- @Idle oil temp >200: 1-1.5
- @High RPM: 4-5
Oil Temps:
- Highway Cruise: 205-210
- Spirited Drive: 220-230
- Max Reported: 240-245 (ripping through mountain passes)
Varies all over the place depending upon load and ambient temperature. I have no idea how to define a baseline.
This last trip I saw 245 during climbs (varying from 50 to 90 on speed and mostly above 5K rpm) with an ambient starting in the 90s at the lower elevation and lowering by 30 as we passed 4000 feet. Same trip in the high 80s cruising saw oil temps at 190.
The accompanying GTS (PDK) with its third radiator regulated much better, holding 210 in the more extreme conditions.
Makes me think it may be time for an extra radiator (and larger sway bars, and ceramic brakes, and semi solid motor mounts, and suspension links, and ...). I've avoided the rabbit hole and fear turning on that tap!!!
Edit ... In other climbing conditions in 100F plus ambients I've seen 260 and on cool rainy 40F winter evenings I've been unable to exceed 180.
I've said it before, IMHO the Porsche engineers sacrificed ideal temperature regulation in the interest of not adding weight ... something more akin to Colin Chapman and Lotus.

Pressures on the .2 are computer regulated and the gauge only offers value if you are suffering starvation.

Indeed, in my c2 manual I've never seen above 215F, even on a short track stint.
I think the oil pressure gauge's function is solely to give the driver anxiety. Like, why did that just drop to .1 for 2 seconds? I should keep an eye on it. Wait, it didn't do that again...it should be ok. Wait, it did it again. I should test the oil level. Arrrrggh....
change this thread to a Poll with various ranges... much more effective.
Unless all of us are oil experts (we aren't) all of this is anecdotal anyway.
So your initial question will not be answered here. perfectly good questions.. this is just the wrong way to answer it.

+1 I hit the exact same temps etc....... what freaks us all out is the temps are generally stable for those of us in the north and only jump on hotter days. They appear out of the ordinary. I thought the 3rd radiator would be a fun project, but then we have the issue of driving a cold engine in the winter that leads to seizures, hair loss, and odd rashes in dark places.
I just discovered something I never new before! The Canadian and USA dashboards are different. See below...... I clipped just the oil temp guages from my 2009 Owner Manual.
OMG... we have to get to the bottom of this.... Is Canada that cold of a place? Is Texas the tropics? Can I have a tamale and LaBatts at the same time?
Glad to see these numbers. I'm at around 200 normally, but saw around 233 ( next line) when it was 80 degrees out and I was worried something was wrong. . Florida guys must run the higher number all the tome?
I'm in San Antonio where it gets pretty hot and rarely see it go over 200 in my .1 Turbo. Most of my driving is highway but I often keep it in the 3-4k range for fun passing runs. I don't think I've ever seen it over ~210 to be honest.
Edit: Coolant temp is always rock solid in the middle, the needle never moves once it's warmed up.

Mine is always at 200 F. Since I have a 3rd radiator seems to take forever to get to temp.I have seen it go up to maybe 220 on a couple of 150 mph sprints

My GTS pdk is the same as reported here. Holds 210 regardless of use.
I think there is a conspiracy of some sort. Look at that speedometer.... Canadians drive like wild crazy men....their engines must be different.... high speeds with low temps... they got something special that we don't.
