Really? how easy was the install?

you guys are on crack...i don't care what nissan says...running @ 235f while cruising on the interstate in 6th gear at 80mph on a flat smooth road isn't right. granted it was hot as hell ambient (like 95) but that just doesn't feel right. i think 190-200f in everyday driving is appropriate.

i'm getting a 34 row oil cooler with thermostatic plate to prevent long warmups during the winter and running redline 5w30. will be fine on track days and in the future if i get forced induction.

good luck driving without an oil cooler in the southern u.s.! clearly an issue that nissan should fix.

wish i would have said that

as far as this oil issue goes in my case this is what i have seen with my 09
with 5000 miles on it. in july and and so far in august with outside temps averaging 95 degree's my oil temp is hanging around 210 to 240.
this is stop and go and interstate travel.i am not a gear head so i don't
know what normal should would be. i use 5w30 mobil one and the only thing i have noticed
is the oil seems to have a darker color in between changes than it had with my
350. i love the car but i use to never have to worry about checking the oil at every fill up. at least it doesn't burn any oil.

Apparently, you're the hypocrite. All the data suggests that oil temperature is an issue with the 370z. I've haven't been to another forum (S2ki, Stangnet, evolutionm, ClubRSX, etc.) that had as widespread concern about engine oil temps other than the 370z forums. Heck, the my350z forums doesn't seem to have these issues either.

The cooler was the single best thing I did for my car. Even with a few little headaches, I'd do it all over again.

Hello,

My 370Z has about 350 miles, I drove it sporty to hard in a Malibu canyon by 80 degrees temperature and the oil gage showed 270 degrees for a few miles then went down to about 250 degrees for the rest of the way until home (10 miles). From what I read the car runs hot and I am worried that if I install the Stillen exhaust and air intake and something wrong happens due to the heat they will void my engine warranty. Should I be worried? What needs to be done?

I'm surprise your car did not went into limp mode. I would not worry other than getting mad, that is why you have the factory warranty.

However, the Stillen exhaust and air intake does not have anything to do with the car oil overheating. The The Magnuson-Moss Warranty Act protects you from stupid service department that might want to blame other problems on exhaust and air intake as per your case.

270... dang that's hot. even in 85F in my area my oil temp is no more than 220, moderate driving to sometimes wot. :D

i know how involving malibu canyon is, so i dont doubt it. :p watch your brakes boil
coming down tuna canyon quickly. lol

Give the car time to break in....Most have found oil temps will drop and it becomes a non issue after awhile..

Thanks guy, I will change the oil after 2500 miles and get some better oil than Nissan provides the car with. I am not too worried about the oil heat issue as long as I do not see 295 degrees I feel ok.

Concerning Malibu canyons, they are tough on the car but not that tough... Not even close to what the car would experience on a track which is what had me worried. I guess a dealer installed Nismo oil cooler might help, better oil and a Stillen front bumper which give more air to all the cooling parts.

This high oil temp is bugging me.

92° outside and while just rolling down the highway (with no one in front of me) at 68mph I was reading 245° which sounds a bit hot for not even being over 2700 RPM. It did not go down for MILES just stayed at 245°.

I switched over to redline 5W30 this weekend when the car hit 2339 miles on the clock. I was hoping that the oil might make a difference, but that is not the case, in fact I think it is running hotter.

Nissan owes me an oil cooler...

its getting hot in Texas. my z has right at 10,000 miles and worst I've seen was driving back from San Antonio to Austin couple weeks back. outside temp was 102F... Oil temp 230-235. Cruising sixth gear around 70-80 mph light traffic on I35. While not terrible I do think thats hot for cruising in top gear on a flat smooth interstate freeway. Once I exited the interstate near home and sat at the first red light the temp came down to 220 pretty quick.

Nissan's answer to you is that 240-250 is not a problem (as far as they are concerned). I do mostly agree with that because if you didn't have an oil temp gauge you wouldn't be complaining. I.e. sans looking at the temp gauge and freaking out the car wasn't misbehaving.

I've probably hit 260 on the street when pushing it a bit without a cooler, again not really a problem in small doses. If you're going to push the car hard then you need a cooler, otherwise put some black tape over the gauge and forget it's there until you hit limp mode for the first time. If you manage to achieve limp mode then you need a cooler.

Nissan knew about the oil temp issue.
That is the main reason they put a oil temp gauge in the car.
But i do agree with one poster if it wasn't there no one
would be so worked up over it. i'd rather have a better coolant
temp gauge than the cheap one we have now to me that is
more important.
