So, todays advanced oil formulas must meet certain specs in order to get API SM or SN certification. One criteria is to protect the engine with oil temps up to 300F. Don't believe me? Go look it up. So the Z goes into limp mode at 280F. Makes sense to go into limp mode below 300F vice higher than 300F. 260F is no longer an issue but some choose to hold onto old ideas about oil temps. Nissan now adds an oil cooler of sorts but no matter what you own, if your gonna track a vehicle, you need an oil cooler - oem or after market.

Oil breaks down significantly faster when operated above 230ish.

So while, yes, you are correct in saying that 260* temps are not a major concern by themselves, they do open up the door to additional complications.


There are some good G37 threads on BITOG for those interested...
