Oil temperature
 

Dear Nissan's customer service reps, techs, enthusiast and people that take Nissan's side on this
I have a Nissan's 2010 touring roadster with sport package. This car comes with Nissan's famous and most used VQ37VHR engine. This engine has a problem with high oil temperature and will go into limp mode at about 280 degrees. Nissan knew of this condition thus the limp mode. I don't track my car but I have been reading that track users in these cars do produce those temperatures. So when trackers complain about a few laps around the track and limp mode kicks in; I can understand Nissan's responds of," add a mode for cooling your oil", even though this car is advertised as a "sport car". But us cool drivers are finding out that just light spirited driving and driving in hot climates or stuck in traffic pushes the car into high temperatures like 280 degrees. Now to my question; how hot is hot? My car temperature is normally around 180-220. But with spirited driven or stuck in traffic on a hot day has reach up to 260. My point is even going into limp mode stuck in traffic will not reduce the oil temperature. Are these high temperature going to cause damage within the engine at some point. Don't you think Nissan's owes us an oil cooler or some other solutions to this premeditated future damages to our investments. I know this is a dead horse issue but.... thinks in advance for your help in this matter....Z fans or disappointed consumers awaits your response.

What is this hot oil you speak of? Also, eagerly awaiting response from Nissan Corp to your post :ugh2:

Mine has hit 245ish when driving spiritedly on the highway, and I'm pretty sure your oil should not reach a certain temp much higher than that or it needs to be changed right away because the temps change the viscosity of the oil past operating specs or something, but maybe the temp would have to be like 300 and that's why limp mode kicks in at 280 or around there. Looking into oil coolers is a must, especially in TX where I'm at

I have a 2012 Z comes with a small oil cooler and driving the car on the toll way pushing it here and there not constant at all at night have reached 260 i think nissan really f*cked the 370z in many areas i have 9k miles and im already getting a transmission put in

n i was using eneos 5w40 right now i just put in motul 300v 5w40 hoping i see a difference in oil temps and also i started my car today not even 2 mins later the car was already at operating temp (coolant temp) this car gets hot quick and stays hot i wish they would of done what mazda did with the rx8 for coolant temps is keep the fans on for a little while after the car is turned off to help cool the coolant and prevent some damage to the engine.

do tb bypasses,oil catch cans,and some under hood cooling mods with a toggle switch to your fans.even in a run i did to 150 mph in 75 ambient with high humidity.my oil only went to 219 from 200 oil temp at beginning run and cooled back down rather quick.up rev fan control is a must !!! i use pennzoil platinum

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.

This is an old topic but Nissan already replied to this argument. They said they didn't put an oil cooler to keep the price affordable. That for normal public driving they don't think that will be a problem but if there is high temp problems that's why the computer protect the engine with the limp mode. So that is the protection Nissan installed.

But they also replied that for track enthusiast people to go ahead and buy an oil cooler.

I agree that Nissan messed up but adding an Oil Cooler is a small price to pay to make an awesome car perform even better.

^^^^^^ What he said.

Mr. IDZRVIT,
This is all we are asking of NISSAN. To assure us that our engines are not damage from high oil temperatures.(what we might think are high temperatures) The statements you made about how oils and engines have advanced to the point should be placed in NISSAN'S genetic response to the hundreds or thousands of people worried about their investments. Could you please direct us, simply layman's to this information concerning modern oil breakdowns and at what temperatures. I have read many article concerning oil temperature breakdown and not come across the number you speak of. Thanks in advance to your response.

where can i find all the info to do these mods? tb bypass?? keeping the oil temp down is important at least to me as i want my investment to last me i dont want to have trouble with the engine before i finish paying the car off and run out of warranty that would suck lol

Just put in a 25 row oil cooler with thermostatic plate. All problems resolved you won't see over 220 even driving insane. I live in Houston and drive in 5:00 PM traffic where I see temps up 110 temps never go above 200 running normal and only up to 220 when flooring the heck out of it for sustained periods.

and adding an oil cooler is all good but it still doesnt have anything to do with the coolant and how hot it gets which is why fan control is recommended.now,you will want to remove as much heat as possible from going into the engine via intake unless im missing something lol.the tb bypass and catch cans helps to do just that.:)

If you have a 2012 and you're getting into limp mode or near it on the street, you are driving like an idiot or there is something wrong with your car.
