Normal cruising oil temp?

2010 C4S with PDK ... 190 to 225 depending on speed. Traffic equals slow and no traffic equals higher speeds. Both of these equal higher temperatures.
Ambient temp makes a difference as well.
Air conditioner load can also affect oil temp.
Water temp is always 175, but that's because the computer controls the gauge.

Here's a thread of mine you may want to take a quick peruse with an incident I had last week, which ended up replacing the left front rad fan: https://rennlist.com/forums/997-foru...questions.html

I think the ambient temp (really, the delta T) matters a lot when it's hot outside 95, 100, 105...
I have a low temp tstat and when it was 100-102 outside, and driving a bit spiritedly, I got it up to 240. On a day with about the same outside temp but no spiritedness, my final temp after about 18 miles of driving was 225-ish. Equivalent route in the morning (cooler ambient) I top out at 205-ish. The oil T values are estimates from looking at the oil temp gage.
In higher ambients the oil temp recovery time is much slower after spirited driving when compared to lower ambients - this suggests, I think, it needs a bit more cooling capacity - probably through the extra radiator kit. But I guess could be accomplished with more fan time if in stop and go traffic, or spinning the water pump faster (if correlated with low RPM driving) ...
For the record, I have duplicated these values after cleaning the radiator/evaporator area - it wasn't very dirty to begin with.

normal around 200, bad stop and go 220 range. When I first saw that oil needle climb over 200 I was sweating bullets, but I think that its normal now.
water temp 175 never higher

Many gauges on Porsche are just like in an aeroplane: they should be either completely vertical or horizontal to be in "normal" mode.
When the oil temp is completely horizontal it's normal temp. When water temp is completely vertical it's in normal range.
It made like this so you should see easily if something is wrong just by glancing the gauges
Of cause it's not valid for the other gauges since they depend on rpm or speed.

In Atlanta it was about 92 the other day and in stop go traffic with ac on mine was close to 249. Everything checks out ok but it is still high to me. I turned off ac and it dropped a little. I just don't think these cars cool very well when it's this hot outside. There are many posts recently about high oil temps.

In Texas heat, 200 - 210 under normal load at highway speed. Sport Plus and Sport it climbs any 10 - 20 degrees. I don't use A.C. unless wife is in car, and, if I do, it's in normal mode. Have not noticed much climb in temps under those conditions.
The water temp - if it ever moves off from 175, I'd probably plotz...T

Mine used to get up to around 225 in normal, non-spirited driving in hot weather. With the RND engine in it with the LN low-temp stat, it's been staying just a gnat's whisker above the 200 mark under the same usage.
