What are the typical max oil temps you see during spirited and track driving? I was up to 250 for a short period of time this weekend. At what temperature should I start getting concerned and back off to let it cool down? 3rd radiator needed?
I've seen similar temperature on a hot track day. With good synthetic oil that should be no problem. I'm running Motul 81000 5W-40 and if I planned to do a lot of track days, I might consider a slightly heavier oil.
i wouldnt worry about it since there are a lot of fail safe features build into the car (ie warnings and limp modes). until you reach that point, i say drive it like you stole it :-)
Look to our 300V line of oils. Genrally speaking, you should see a 10-15F degree differnce vs our 8100 line as well as Redline, Brad Penn, Valvoline, Mobil 1 etc. Also up to 7+ HP vs the competition as well. See below. -Nick
Oil 1: Mobil 1 0W40
Oil 2: Castrol Edge 0W40
Oil 3: TOTAL 9000 5W40
Oil 4: Pennzoil Ultra 5W40
I run around 40 track days per year and have seen 280+ several times. I also pull my true coolant temps from the CAN bus and saw some pretty high numbers (210+) so I installed the center radiator (note that the display on the MFD showed 194 the entire time). Before the center radiator I had to short shift at 6K in order to keep the temps down. Will report back later on the success of the center radiator’s effectiveness during super hot July and August events. Fingers crossed...

Why would you recommend a motorcycle oil for automobile use.

We have 2 lines of 300V- an automotive line (metal can) and a powersport line (black bottle):
And no, they are not the same oils repackaged. One is much higher in moly content for instance (auto version) due to no wet clutch compatibility challenges thus allowing for higher power potential. -Nick

Thank you!
My 991.1 C2S would run near 240° when pushed on the track in 85° weather, and i would have added the middle radiator if I had done much of that.
But my 991.2 C2S/X51 seldom goes over 200-210° Now i see why Porsche did not include the middle radiator on the. 991.2 GTS. Maybe it's telling me that b4 i add the middle radiator on this one i need one of those tunes for 530 HP and 480 ft-lbs 😃

That's surprising because I saw well over 240 deg oil temp on my base 991.2 at the track. It was, however, a near-100 degree day.
I use 5W-50. On hot 100F days, I see a tick over 250F without a 3rd radiator. As the other person said, the car will go into limp mode if it detects any issues so I wouldn't worry about it.
