Reset the ECU yesterday and went for a test run, IDK if this is specific to my vehicle but the temps soared again to about 250-260. They have leveled off again this morning, i have been on about 5 trips since the reset. Hmmm as far the oil bieng the cause, I doubt it...but the more and more i read on bitog, here, and look at oil analysis, German Castrol seems to the perfect fit for this car. Anyways I'm really starting to beleive the ecu could be 1 of the culprits for high temps...

That really sounds like either a glitch or a sensor re-calibration issue.

That said, it does raise the question of how accurate the OEM temp sensor is...

I guess if anyone is feeling adventurous, they could install a secondary temp probe to compare and contrast...

:iagree: It's possible the guage reading isn't the actual oil temperature. I'm not sure how the analog guage is wired. Anyone know if it connects directly to the sensor or the ecu?

This is an ongoing problem that Nissan needs to deal with!

I wouldnt worry to much about it if it levels off... Get an oil cooler when you get the cash though, Can only help.
