Oil temperature

red6spd

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.

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.

im not reaching limp mode but i dont like how hot it gets and i live in texas where its really f*cking hot

gurneyeagle

I'm in Houston too and crawling down Hwy 59 for ten miles in stop and go traffic in last summer's insane 110°+ temps never saw my temp gauge above 220°. Running it hard on the twisties in the Hill Country has never seen the temp above 220° either.

Haven't tracked the car yet, but if I do, I'd seriously consider getting an oil cooler.

ive seen temps above 240 but not 280 when limp mode comes on, and it comes with an oil cooler maybe its not enough? and ive seen 220 alot in traffic i try to get around someone it just gets up their not really pushing it just going to 4-4.5k rpm for a burst of speed and then back to cruising in 6th gear or back to neutral depending on driving situation i'll look at it closely tomorrow on my way to and from work. i'll be to give more of an exact number and maybe the oil change to motul will keep the temps down as well but i'll see

Catch cans and TB coolant bypass have almost nothing to do with oil temps .

There's some easy things you can do: e.g. change your coolant mix (more (distilled!)water, say 70/30 instead of 50/50) and use UpRev to turn on the fans earlier. There are already some really long threads on this whole topic that started years ago, you can read them.

I really wouldn't worry about it unless your temps are running away from you out past 250, which it really shouldn't do idling in hot traffic. It's high RPMs combined with low speeds (low airflow) that are going to run up the temp. Try a higher gear if you're seeing temp spikes in traffic (and if you don't have UpRev-modded fan speed control, make sure your AC is on: it keeps the fans running). I could easily see someone crawling along in 5-20 mph traffic staying in first gear the whole time having more problems than, say, someone who goes ahead and uses 2nd (or whatever applicable gear that doesn't drop the revs so low as to lug the engine out).

not really worried about coolant temps just that it gets up to temp really quick more worried about oil temp

wstar

Coolant temps and oil temps are related. Anything you do to keep the block cooler will help with the oil temp situation as well. The reason you don't see much movement on your coolant temp gauge is because the dots are set up on a non-linear scale where the "normal" dot has a very wide range of temps

kenny's 370z

which is why i told him about the tb bypass and catch can.both of which provide cooler air going into the block...thats not going to fix his issues without a fan mod but every little bit helps

wstar

The TB Bypass makes a (very minor) difference in intake air temperature, but that's not really going to affect oil/coolant temps. Catch can has nothing to do with any kind of temperature really (at least, no pragmatic effect from the tiny volume of slightly-cooler PCV airflow, but even again, that's intake air not radiator-cooling air).

Ugh that gauge is causing Nissan and this forum more headache then its worth. Look at the corvettes, temps approaching 300F (150C) are common and no limp mode.. In most cars you have no idea what the temps are. I bet most stock sports cars if taken to the track will get to 280+ no problem and even day to day driving will get them there too. The thing is you don't know in these other cars because there is no gauge.

If Nissan could require synthetic they wouldn't even need to put that limp mode in since synthetics can take well over 280 deg.

There is no way you can reach 280 to hit limp mode by just spirited driving in the streets. You will see these temperatures if you track your car for sure but not just driving around town a little aggresive. Why? Because you have traffic lights, stop signs, yield signs, pedestrians, other cars, trucks which you will need to slow down for. As fast as your car heats up to normal operating temperature, it will cool just as fast while its resting at idle. Unless you keep your shifts between 6 to 7 k RPMs repeatedly and extended periods of time which of course no one in their right minds would do.

Nissan didn't include an oil cooler because 95 percent of the people who own it will never track their cars. The Z is still a sports car with or without an oil cooler. It may not be a full track ready car (Non-Nismo) but it does its job in bringing a smile to your face when you press on the accelerator and weave in and out of traffic. Irregarless of the oil cooler being a factor in choosing to track your car, consider the factory warranty as well. You can void your warranty if the dealer suspects any abnormal wear and tear on your car tied with track friendly add-on modifications (oil cooler), ect. LOL

To add, with today's synthetic oils, you dont have to worry much about temperatures reaching 280. Synthetic oils are tested all the time to keep their viscosity almost intact to temperature approaching 400 fahrengeit if not more. As pain in the *** limp mode may be to some, Nissan includes the limp mode to cover all their bases since not everyone adds synthetic oil in their cars you know.

Go get us a new gas tank that won't fuel starve too, thanks!

FWIW, I had a really hot-weather track event this weekend at MSR-Houston, and I was pushing the engine really hard. I'm on a 19-row cooler and at the very end of the hottest sessions I'd peak right at 260. That's basically 20-25 minutes of non-stop high-RPM and heavy throttle time. In the space of my single cool-down lap it would drop right back to at least 240, and it'd be back to 220 by the time I reached my spot in the paddock. On the cooler (weather) runs of the weekend, the numbers would drop about 10 degrees.

Not ideal, I really need a 25-row on the hot days around here, but didn't hurt anything either, other than making me want to swap this oil out a little sooner than usual. I just can't imagine what someone would have to do on the street to hit 260 even without an oil cooler, much less 280 (which is the first layer of ECU limp-mode protection).
