Temps depends a bit on the track you run so you may not have experienced a "hot" track. I've seen 310 oil and 240's water in 95 degree heat before I laid off for a few laps. Other tracks the temps didn't get near that high because there were less long straights. I'm not even FI so you'll see more heat than others. A radiator upgrade was not enough to keep my oil temp low and the flexalite is the biggest on market that I know of. If I were you I'd get oil temp and IAT gauges in your line of sight. In the 230's the car is pulling timing so that may be helping reduce your temps somewhat too.

I didn't realize what I was saying until it was pointed out.

Not necessarily. Your coolant temps will come down much faster than the oil. Quality synthetics can handle temps in the 270+ range for a time, and I assume most who track don't run their oil for over 3000 miles of mixed driving. Cheap insurance.

I follow the European manual specs, which is Dexos2 (ACEA C3). I think the Gen6 track recommendation is for Dexos2 as well. There are some 5w-30s that meet it. The bonus is above 230f, where these oils stay in grade better.

I run redline 10w30 on track with a tstst and never see the oil over 255 on 100 degree track day with no issues. I just added a 25 row oil cooler to help cooling. I had a long talk with the engineers at redline and they said the oil getting at those temps wasn’t even close to being a issue.

Indeed.

For a Group V oil, it should be eating those temps for breakfast, otherwise what is the point really? It was the whole point of Group V, lol.
