There is a Nissan TSB that says to use Nissan's Ester oil when a customer is complaining about excessive valvetrain noise. Nissan also has a bunch of marketing verbiage as to why everyone should be using their Ester oil, but the only real practical reason that they seem to have is to reduce valvetrain noise, not to reduce oil temps or eliminate the need for an oil cooler if you're tracking your car.

The service writer at the dealer said that they were getting complaints about oil temps and that the Nissan recommended ester oil should make it run cooler so i changed the oil, my oil temps are between 220-240 never been on the track, dont know what was in the Z originally but started using their ester oil at 700 miles and change it at every 1500 miles after that. have 5k on it now, oil temps are still the same, is the cooler made by nissan?
