Same situation here with the heat in my 370Z. however, I think the car was still new and the tolerances were still pretty tight. I was in Houston running around on the interstates there at an ambient of around 101-103, and I was spiking temps of 240-245 with just a little sprint of about 30-40 seconds just as you mentioned. I did install a 19 row oil cooler (not tracking the car), and my temps now are running in the 180-200 tops, even with high ambient temps and very spirited driving. The downside is with the morning mid fifties ambients, I can barely get the temps up to 180 for the 7 mile drive to work. I will need to blank the cooler off for the winter for sure now with cooler temps/maybe some freezing ambients as well.
I run Valvoline full synthetic 10W30 with a Purolator PureOne filter by the way.
