I'm not saying remove any type of stickied information regarding oil temperature. I just don't really see the point of this thread continuing the way it has been for the past while with it dying until someone new joins and then causing a few members who haven't been that worried to panic.

You could apply what I was talking about early with what you suggested. Keep the first reply of the thread updated with everything that's been found out. My suggestion was to just start a new thread, make it have one reply that contains all relevant information, sticky it and lock it. New people can then read the post and not have to freak out and worry other members in the process.

I like that idea, go for it, unless anyone else has any objections.

Just got back last night from a 320~ mile cruise through the hill country at high pace. I tried to get my car to get hot (4-6k rpm long holds), but the hottest it saw was 210 oil temps. Water stayed below 190 as well.

Track event is next weekend which will be the real test.

Made it to the track finally. Outside temps around 80. My Water never got above 210 degrees but my oil temps did hit 250 degrees. But didn't go higher. I was keeping it in 3rd gear most of the track near redline.

I'm now running a dual-core oil cooler that was custom prepared by Redline Motorsports in Tempe, AZ... using Motul 300v 10-40 and the car is well broken in... Ran today in 110F ambient at Phoenix International Raceway... never got above 250F! I'm now satisfied that my oil temp issues are behind me...

Generally agree with the takeways a few posts ago...

• any track 370z needs a cooler...
• for hotter climates, consider dual core or oversized core... the single core offers from stillen and others were inadequate
• as for autocross, not sure... but makes sense you don't need one for these kinds of short runs
• road going Z's probably don't need one unless you drive aggressively and are in warmer climate...
• finally, nissan screwed the pooch

Wow, all this discussion. I live in West Virgina, and took the Z out today on some country back roads... Drove lively, not insane. Notice the oil temp went up to about 250 or so, the hottest I have seen it climb. The car turned 1700 miles on that drive. The Z is my daily driver, and I commute 120 miles, all highway. The most I see it climb to is 220...
The dealership I purchased it from has a "powertrain for life" deal going on. For the life of your car, the dealership will guarantee your engine. If it dies, and you have gone to them every time for an oil change, they replace your engine. For this reason (I am not really planning on tracking the car), I am not that concerned about the oil temp issue!

Travis,

Glad to hear the dual cooler is working for you.

Hi, i am new to this forum, and currently run a 1995 M3 which i was considering selling to get this car over the 135i, with all the oil & diff issues it is making me think twice about getting one, i am an avid track and autocross driver and love spirited driving when i get the oppotunity, now my car has 125,000 miles on it and hasent had a problem yet even after multiple HPDE events and even more autox, now is this something i should be severly worried about being a resident of florida, or is there anything i can do to help speed up the process and get on nissan to provide factory cooler. i understand i can buy an aftermarket one but i believe a car should do what it is advertised to do.

At this point there is no cooler, and the 2010 has no cooler. Someone posted a pic of the 2010 Nismo, and a cooler was spoted behind the grill. That led to speculation, will the 2010 Nismo have a cooler? Was that just there for the magazines to test drive, as the early cars for 2009 had for the journalists? Who knows at this point.

I love my Z. If I lived in Florida and tracked/auto crossed the car, I would buy one and add an aftermarket cooler, problem solved. I live in SC, and it gets very hot here in the summer. Next spring, I will probably add a cooler and I don't track my car. I never hit limp mode, but I can hit 250 degrees with spirited driving and stop and go traffic. I will feel more comfortable with the longevity of the engine if I add one. I would not let this stop you from buying the car, it is a great machine!

John

Haven't read this whole string, but mine is late year and has an oil cooler stock. Touring edition only, no sport or Nismo.

^^^^ ok come again???


you got a stock oil cooler? me thinks not

I'll grab you a pic. I believe there is a power steering cooler as well. Check your production date, could be a late year change.

I don't drive my car hard often but have run the snot out of it a time or two and never seen my oil go over 230

waiting on pics

Reviewed pics here I guess it is the same. i was thinking mine was on the other side(or both). Still no oil temp issues at all. We ran it at around 135mph for a LONG time on the back roads of TX. Still no bad buildup. Maybe hard stop and run or track with slow corners but no issues with high speed or daily driving.

No it doesn't. Yours has a power steering cooler not a oil cooler.
