This is my response to you...(you know who you are).
I called Nissan North America today and went to 2 nissan dealerships, gave them my vin#, they ALL told me the same thing,..the 2013 370z is equipped with an oil cooler! That saves me $$$, Im happy to hear that since Im planning to install an oil cooler in the future...
My oil temps is around 180F to 200F on a hot day(120F) in Nevada, cruising around 90 to 120mph at death valley...
I drove from san francisco to san diego to las vegas!
Thank you!!!
