Whatever I bought, I would probably know if it had an oil cooler or not.



:stirthepot:

The Nissan stock oil cooler is a piece of garbage. Yet another Nissan bandaid - just like using GT-R fluid to fix failing CSC. Add an aftermarket oil cooler for real cooling.

Another reason why I wouldnt buy a Stang.

It's not a piece of garbage or a band-aid, it's a standard oil-to-water oil heater/cooler as used on passenger vehicles. That's what the Z is... A passenger vehicle. It's not a race car.

If you want to go to the track, track prep your car. For damned near any car (esp. one that makes power) that means adding additional cooling, like an oil to air cooler.

:rolleyes:

I'm not talking about it running hot on the track. I'm talking about cruise control at 85ish mph on the highway and seeing 250F+ temps on the oil temp gauge. The 2012 I saw this happen in was 100% stock and wasn't running noticeably cooler than my 2011 with no stock cooler. Both were pegged between 250-255F on the gauge. The stock cooler is a worthless piece of garbage in my experience :twocents:

How hot was it outside when that happened? I drove to Atlanta last year (150 miles) in 95+ degree heat last year and had nowhere close to 250F temps. Hell, I don't think it even went above 220F.

August in Texas. Definitely over 100F. Speed is a big factor as well. We were on a toll road with 85 mph speed limit. At 70 mph, I've never had an issue with temps - typically right around 225F or so. But I've found that extra 15-20 mph increases oil temps significantly during the Texas summer weather.

:iagree:

:gtfo2: lolol hey how was i suppose to know i thought it only applied to the nismo because my oil temps were still high as **** haha

Well excuuuuuuuuuse me, Mr. 85 mph on the highway in Texas heat. :bowrofl:

I've owned with and without, and the oil cooler made a noticeable difference. Let's just say under the same conditions where my 2011 would run 240 - 250 degrees I haven't seen the oil-cooler-equipped cars go above 220. :twocents:

What i could afford then and now are two different aspects. 4 years ago...
If icouldn't get a Z, it would've been the 1LE camaro or a G37ipl used cuz i won't pay $51k for one. I don't see the value at that price so, something with less than 10,000 miles for $41,000 to 43k

You have a lot more data that I do then :tiphat:

As long as I'm not on the gas, I have no problems with temps. Easier said than done though :icon17: :driving:

Well I recall all the controversy about the oil coolers when I had my 2011 and people were having heat problems. My car would get up to 250 if I pushed it pretty hard and it was 90 - 100 degrees out. For example, driving for extended periods in 5th gear, with a heavy foot, in the 75 - 80 mph range. But still, I never got above 240 - 250 degrees. I remember thinking people must be driving like ******* maniacs to go into limp mode or even get above 250 degrees. Even said so many times to people, but they insisted they really weren't pushing the car that hard.

With the cooler, I've kept an eye on it as well. Same driving, same "Indiana in July" weather (we had about 12 days in a row >100 degrees last year, not exactly Texas, but not exactly refreshingly cool) and I honestly can't remember the last time I saw my oil temp above 220 degrees.

So... I wonder if certain cars run warmer, and even with the oil cooler, certain cars still run warmer? Possibly yours runs fairly cool for a cooler-less car, and the 2012 you were with runs on the hot side? I really don't know, but there does seem to be a very different set of experiences depending on who you ask, and it's not because I'm putting around at 56 mph. :driving: :icon17:

I have seen my oil temps climb to 220 is at the drag strip with about 4 passes. Mostly in the evening when temps start to drop and humidity rises. I shut my z down for about 30 minutes before I attempt to run any more passes. Performance drops significantly after 220 tho

I certainly don't think I have a cooler running Z from what I have seen. In hot Texas weather, its at 220F minimum pretty much no matter what speed. And as soon as I get on it a bit, that cranks up 20F or more very easily. If I'm cruising at highway speeds (at 220F already) and come to a stop light, I can hit 250F just coming off the line if I get on it hard - now it will cool down reasonably quick at speed once I get off the gas. But if you're in semi-hot weather and over 4500 RPMs or so, oil temps will increase continuously regardless of your speed. In my experience, that is. Your example of 5th gear at 80 mph is only like 3500 RPMs or so.

I just ran FM 2222 yesterday around 85F. In 3rd gear most of the time between 4K-6K RPMs I hit 260F temp after just a mile or so. I shifted into 4th for the last few curves just to back it off a bit. But I know the capability of the car. I push it hard for brief periods at a time, then back off. It just can't handle repeated driving at higher RPMs, especially in hotter temps. My feeling about the stock cooler is that it doesn't provide significantly more cooling during hard driving and its not really needed for DD or cruising. I bet I could hit limp mode (even with the stock cooler) if I cruised in 2nd gear long enough at 40-50 mph.

And let's be clear here; I don't have any problems with temps when I'm not driving hard or at high RPMs. Very few roads in the country would give the Z problems with temps while just cruising - it's only ever been a problem for me because I just happen to live near the highest speed limit in the country in a hot climate. And one particular time, I was cruising with a 2012 with stock cooler that was running just as hot, leading me to believe the stock cooler wasn't helping much.

I also have R2C intakes with metal tubes, so my IATs easily get high enough for the ECU to start reducing power. I'm sure this contributes to higher temps throughout the engine bay. Another reason I'm fairly certain my Z is not one running on the cooler side.
