You must have oil coolers. I do 250 with in town stop n go driving. I saw 295 with 65 ambient last weekend (track day). Your standard issue oil is a premium grade and I say there's no additional thermal benefit with any different oil until you get heat conduction improvement with colloidal graphites or molys.....and additives are a no-no with our cars.
OP- G R E A T sharing! Congrats.
