Oil Temperatures ?
 

How hot is too hot. What temperature is detrimental to the engine?

I think at 260 degrees F is when it goes into a safe mode automatically, cutting significant power to the engine. I'm considering an oil cooler as I hit 220 with no effort on the highway, at least where I'm at in Florida where temperature and humidity are both always high.

Good! I did not know it has a safe mode. Txs

I don't get worried until my oil temp gets above 240 or so (200-220 seems to be normal). As mentioned above, the car will protect itself when the oil temp gets to 260 or there about. The oil can take up to about 300 F.

I would hit 220-240 with spirited driving and once I installed the 25 row cooler I see 190-210 and 220 if I push her hard.

Sounds nice can't wait to have my cooler !

300F. Read the test requirements for new SM/SN API certified oils. Why do you think the Z engineers decided on the limp mode temp of ~280F and not 260, 240, 264, 228, etc? The 260F temp limit is passe and old oil technology. Newer materials technology can withstand higher temps for modern cars thus the requirement for SM/SN oils.

This is correct. Stage one limp mode isn't until 280F, stage two limp mode is 300F but probably pretty difficult to reach when already restricted.

Synthetic oils can handle the high temperatures much better, but even they suffer some break down if above 260F for an extended period. It is a good idea to shorten your oil change interval if your engine spends time at high temperatures frequently.

Which cooler did you get?

I rarely get above 220 with normal highway driving

I once knew high oil temps. Since my oil cooler was installed I have actually seen 260 degrees once on a 100 degree day at the track. Otherwise it stays well below. High normal is 220 ish.

What about when we reach 220 and we get some kind of limp mode where it bogs it down on launches? Is that just a myth or a defect on some of our 370Z's? When I get to 220 I notice a bad bogging off the line. I have to launch RPMs at 3K to beat a Civic.

:tup:

Didn't you install the Nissan (Nismo) version or is it someone else I am thinking of?

Not a myth mines does it and there is a noticable difference in power after my oil temp gets over 180 ish or it could be the coolant temp either way yes the hotter the car runs the slower it gets . i have an oil cooler (25 row) and added a switch for the fan it performs way better than previously .
