Here we go again
 

Spring is here and oil temps are up. thought i would just mention. i got into the car and my oil temp moved rapidly up to 200 didn't know why then i realized it was 84 degrees outside :eek:

Oil cooler to the rescue!

Same temps here but my cooler is makin it happen!

I'll get up a little over 180 in traffic, but once I'm movin I'll see it drop down as low at 160-170 again.

you are a wise man Vipor

might be a dumb question but can adding a CBE raise oil temps? haha

220 max degrees yesterday in mountain driving at 84 degrees air temp.

yeah I've been trying to stay in as high a gear as possible these past few days to keep the temps down, but its been in the low 80's here and my temps have been averaging 220-225 in 30+ minutes of regular driving.

It is a shame that Nissan didn't correct the VQ37 VVell's oil temperature problems before releasing it in the Z's. Aside from minor things, that is the main problem we have seen in these cars

I dont think its a major issue unless the car is under excessive load for an extended period of time, but i'd be happy seeing my temps sit comfortably at 180 throughout the driving cycle.

Ya I've been running at 200-220 after some driving. 75 degrees being the ambient tempature. I'm thinking I may want to invest in an oil cooler before the summer

Today was about 80ºF and the Oil Temp on my Z was about 200.

I will recommend for everyone to email your compalin to the Nissan Customer Service email that I provided in another thread and go to Facebook post this in the Discussion Board.

The thing is, the engine temps (coolant) are regulated by the Radiator and thermostat and will remain at approx. 180-190 degrees regardless of the ambient temps (within reason). Higher ambients don't necessarily result in higher oil temps.. 220-230 are perfectly normal oil temps BTW.. Don't like it? quit whining and install a cooler for <$300. Nissan isn't gonna do it for you.

I dont know if auto makes the car oil hotter, i highly doubt it, its prob my buddies lead foot, but my car rarely gets higher than one notch above 220... He sent me a text message of a picure of his oil at 260 lol

It was like 70 degrees out that day.. But his oil is always higher than mine.. we cruise together sometimes and no matter when we check it even if were following at similar speeds his is always at least 10 degrees higher..

His is auto mine is 6m ... dount it matters but his car def runs hotter almost always...

He is thinking about a cooler now , but imo I dont see a reason to get one unless you track it. Is 240-250 really that bad for your engine ?

I don't understand why people are concerned about oil temps of 200-230F. Everyone wants to have thick oil and a cold engine running at 160F all the time? Until my car is having issues of persistent 260F+ temps, I'm just going to enjoy the piece of mind I have WITHOUT an oil cooler (no blown hoses, no leaks, etc).

:iagree:

:iagree: x2 except the comment about waiting until oil is over 260F, by then you've done damage no doubt.

My oil temps averaged around 190 while driving in the mountains. Temp was around 65 degrees. It hit 220 once when i was sitting in a parking lot idling.

Hovering slightly above 200 won't hurt anything. And like others have said I just don't want to have to worry about the problems caused by an oil cooler.

Anything over 240 is bad. Anything under 240 is normal. This applies to any engine, not just the VQ37.

I doubt anyone will go near 240 unless they are on a racetrack.

You people should read this and quit yet bellyachin'

Motor oil - Wikipedia, the free encyclopedia

I totally agree.... If this was a major issue, they would of fixed it for the 2010's.. Until my car engine locks up or falls apart due to high temp, I'm not worried about it... :shakes head:

:werd: in fact, if the Z didn't come equipped with an oil temp gauge, it would be a non-issue.

Yeah people like to make a big deal over nothing.

temps never came higher than the normal temperature here.

even with some high acceleration and high revving

I open a Topic in the Nissan North America in Facebook for those that might have or having a problem/issue/concern with the Oil Temp to post there.

That way the issue/concern will get notice by the upper food chain in Nissan.

And it also said this:

The journal bearings are removed from the test engine and scrutinized for any wear. If the wear appears excessive, the oil doesn't get SM certification. Seems like there is a helluva lot of SM certified oils on the shelves of auto parts stores so they must be passing the test for GF-4.

There will always be non-believers and skeptics. I'm happy with my SM oil knowing the above.

EXACTLY!!!!

The last few vehicles I'ved owned all had the same temps...not understanding all this fuss. :confused:

:iagree:

Rep for sure on that one. :bowrofl:

do u track your car? how is it without the cooler? i would like to begin tracking this summer but im conflicted between the risk of oil cooler leaks and the possibility of destroying the engine as a result or on the other hand the car overheating and shutting down after 5 min on the track.

I agree with that! If you want to track this car then, yes, an oil cooler is recommended. But daily usage I would think we are ok! (Of course the failing oil coolers are scary also)

I generally don't see this car as a track car. To me it's more of a touring/ sport coupe for the road. It takes so much to make this car competitive for the track in my opinion. (Just my 2 cents of course) I've gotten to drive quite a few cars on the track so I'm basing it off that history. :driving:

Even though the thermostat is a 180deg t-stat, the VQ (along with nearly any other engine with a 180deg t-stat) runs a normal coolant temp of 195-210.

Oil temps are going to mirror that...it's normal.

The only thing that really pisses me off about the Z is that Nissan installed factory donut oil coolers on the 3.5L VQ35DE, but not on the high performance VQ37VHR. My 2007 Altima 3.5SE 6MT NEVER NEVER saw oil temps in excess of 240deg...no matter how hard I drove it. Even though the car didn't have an oil temp gauge, it did have a factory oil temp sensor and I monitored that frequently with my Autoenginuity OBD-II scanner.

Just doesn't make sense to me.

Late,

Care to eloborate on which cars you are referring to? I am really curious...
