For you I would recommend the mobil 1 0w-40. It's a thin 40 and it's the european formula which is vastly superior than any USA Mobil 1 offering. Secondly, if you're seeing 280F oil temps at the track, you don't necessarily need to change your oil immediately but you DO need to run a 40 Cem because these cars do NOT like making oil pressure when the oil is very hot. That is extremely well documented on this very forum.
I run 0w-30 in my DD only FRS period. If I were doing double duty then the first thing I would switch to is a 0w-40.
