370z Nismo here... Haven't read all posts (not even close) Oil temps on highway's stay's about 190 ish. Drove around a lake tonight (tons of twists but maybe top speeds of 30mph) Car reached 220. I've seen it a few times climb a little above these temps. What concerns me the most... Car is under an extreme break-in by the book. 612 miles on her so far. Not revving above 4k like the books says. So what happens to 220 degrees past 4k rpms? I'm scared to find out.

Well that day was today. Although some could argue that 250-260F isn't "that bad..." on a car that is NA and brand new... I would totally disagree.

Today was my first spirited driving with a few WOT pulls and mostly 5-6k strong pulls. WOW how fast that oil rose to 250, it was unreal. It took less than 5 minutes at street temps of 85F.

So before I go to my Next auto X. I was doing some research and came across this site. Has anybody used this product yet? Has it successfully cured the 370's issue?

I know this thread isn't the fix one but rather the "jump aboard the recall" bandwagon. (which I am all for BTW cause... WTF! right?) But I am also not interested in driving my 40k sports car like my grandma. Till Nissan gets their acts together which could take 4-ever. So forgive the link.

It looks large enough to do the trick.


Nissan Motorsports Oil Cooler Kit

FYI if you put on the oil cooler it will bump you wayyy up the class ladder for autox. So if you planned on being competitive without spending double value of you car in modifications/tuning I would not recommend installing that.

Secondly I can say with out a shadow of a doubt that you will not have any issues with oil temps at an autox. I run in Houston with ambient temps in the mid to upper 90's and 60 second courses and haven't had any issues at all. Temps rise to around 230 over the course of a run and are then back around 200 before the next one.

whats wrong with you people hahaha my engine did blow out i have pics of my car up already already and nissan replaced the engine under warranty i had around 6600 miles on it.....

Okay, my dad is about to purcahse a Chicane Yellow 370z. Anyway, did the newer Z's between april and may still have the oil temp porblem? Also, will driving it hard occasionally still have the oil temp issue after break in? Thanknk to all! Also, whould we purcahse an oil cooler when we get the car? Any suggestions?

Then post the pics. :shakes head:

All 370Z's of every model currently made has the oil temp problem till Nissan comes out with a Oil cooler from the factory.

I bought mine in April (6MT, Touring, Sport); oil temps have run 220 to 260, depending on ambient air temp and type of driving (all on the street). I love the car and really enjoy driving it. But, I think this is an issue Nissan should address. I've had several conversastions with Nissan NA; bottom line is they say oil temps at this level are ok and will not result in engine damage. I'm not a mechanic or engineer, so I can not really dispute their position. I can say these are the highest oil temps I have ever seen on a sports or performance car that I've driven on the street. I intend to put an oil cooler on my car; just a matter of finding the right product and the right mechanic to do the work.

Have they still not fixed the problem? Also, should my dad purchase the new oil cooler along with it or complain about it before he buys it? My other question is, If you were going to drive the car hard one day but not for an extended period of time, would the temp still shoot up regardless?

There is no "problem" to fix. A cooler is only necessary if your dad intends to track the car. After break-in there are few reported problems of High temps. This has all been blown WAY out of proportion.

My 370's (under 300 miles) oil temp is running around 120-130°F above ambient while driving very easy, like grandma on Sunday. Once I get past the 1200 mile break-in I'll post what my new numbers are.

I don't run my Z on the track nor do I intend to but do drive it like a sports car should be driven.Fast and furious!
Temperature 92 degrees and very humid here in N J and drove the car for a half an hour at 80 mph and oil temp never went above 225! I assume if I were reving at high rpm's going through the gears upshifting and downshifting and manuevering turns quite a bit it would rise considerably.
So it is my belief that for moderate street use in the summer it will be fine.All this talk about a cooler should only be needed on a car that will be taken to the track.Just my 2 cents for what its worth.
By the way I dumped the ester oil and filter at 2800 miles and used Mobil 5-30 from here on in.Engine quiet as before and don't hear a thing!Topped it off and will watch oil consumption from here on in.

Wrong

Right

No point really. Is your car broken in? (More then 5K miles?). Nissan has already made a statement on this. It is not a problem for street cars. They do recommend a cooler if you track. There is nothing they intend to do.

In case you haven't seen Nissan's statement on this:

To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty.
