Oil temperature

IDZRVIT

The oils of today are not the oils of just a few years ago where there was concern hitting temps of 260F or greater. The materials used to build engines have also advanced which require advanced oil formulations because of the higher heat generated by the engines - higher HP = higher engine temps and especially for performance cars. 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.
