Looking at the temps you guys have posted, there are a few cars where the oil isn't getting hot enough you want it to get over 70-80C as some of the additives require heat to work properly. You don't want to overcool the oil, 100C is ideal.

Also, the temps are generally within the safe tolerances for a quality 5w-40 (up to 130C average, with higher peaks). Perhaps with a forged build a 10w-50 would be better if the temp gets over 115C or it burns much oil.

Cheers
