The 370Z has an engine protection system that reduces peak engine speeds when the oil temperature exceeds recommended levels in order to protect against possible engine damage. Aggressive driving of the 370Z on a race track at sustained high engine speeds can cause increases in oil temperature and may activate this engine protection system. To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty.

If you're so concerned about oil temp rising, you can install the Nissan Motorsports oil cooler now (or wait for the OEM Nismo cooler).

I do not have that information. I can ask if you want.

4k rpms is low for that engine and I will say it again 4k is low. I ran my HR at 4k and saw temps get no higher than 210 on my gauge in 105 degree temps.

He was at 240+ with 4k rpms.

<gee> - perhaps you should consider reading more.

Better yet - try and get your Nizmo into limp mode, on the street, without doing anything illegal and/or stupid - like driving the car around at 4K for extended periods of time.

Oh, wait, according to your info, you drive a 350z. Go buy a 370z, drive one around and know that the oil temp issue is being blown out of proportion.

I did the same thing, until I TRIED to get mine to go into limp mode, and was unsuccessful.
