That's a BIG negative and to be honest I'm sick of people telling me I'm driving illegally because my temps are high. Either you haven't read this whole thread or you're ignoring everyone who posts who says they have high oil temps without pushing their car.

My Z sits at 220 as a BASE oil temp. Doing anything more than 6th gear cruising (5th gear cruising for example) will cause temps to hit 240+ in very short order. This is just cruising on the freeway. Forget any kind of sporty driving.

I'll add some info.

Yesterday on my 30 minute drive home my oil temp easily reached a steady235.
It was 102 degrees.
My speed varied between 50-70 depending on the traffic. I'm babying it right now since it only has 800 miles, so there was no "shenanigans" involved.

I can believe it's very easy to push it higher without doing anything illegal when it's hot outside... simple thermodynamics...

Seriously curious...I wonder how many people on here have actually triggered the "limp" mode during street driving?

220 is my normal base temp as well, anything outside cruising along and up they go......... how hi depends on RPMs attained and for how long, as well as air flow and ambient temperatures. 260 is possible without breaking the law or driving recklessly.

It's actually really difficult. Although it's pretty easy to reach 240-250, it takes quite a bit more to reach 280. I certainly haven't done it on the street yet, although it's possible if traffic wasn't in the way. Basically just have to accelerate, brake, corner, over and over a few times for several minutes.

Guys I was invited by Nissan to participate in one on one interview with regards to my z. They are aware of the oil temp issues that's going around our forum. They said there is a factory oil cooler already available for around 400 bucks and installation is I think about 400 bucks also. They said if you don't track the z then you absolutely don't need to get this oil cooler but if you do track it then you should get it. That's from Nissan. End of story. It's your choice if you track or not . Period. Stop debating, there is no sense. You Ytack you get an oil coller, you don't track don't.

I don't track, and I have yet to actually trigger limp mode, but I'm still getting a cooler (going in Tuesday I hope, along with more oil capacity in general). Ambient temp on the car display today was 101. Cruising in high gear it stabilized around 230, which is fine if it would stay there. One little half-mile open stretch with some nice curves came up, and I burned through it at the limit and then accelerated up onto a highway ramp at full throttle. Checked the oil temp as I was bringing it down to a good coasting speed on the highway: 255F. Then I backed off and cruised in 7th under the speed limit a while to get it back to 230.

There's nothing wrong with 255 really, as an occasional burst, but I wouldn't want to sustain that kind of temp, as it affects oil viscosity and oil life. So right now, in the interests of keeping the oil (and thus the engine) in good shape my driving is limited by oil temps. I have to back off and let the car cool occasionally, and/or I have to pop the hood and fan-cool the car when I get home before I shut it down. I don't want to be doing that, and frankly shouldn't have to. Luckily the aftermarket has fixes :)

:iagree:

What cooler are you putting in Tuesday?

John

Stillen's original (current) cooler kit, + AAM's oil pan spacer to add more capacity to the system.

Do you have the information on this cooler, part number etc. Not aware of any nissan oil cooler besides the nismo - c part that is $760

I live in Miami Beach and I drive about 33 miles to Fort Lauderdale. The afternoon temperatures have been 85-90 F and in 6 gear doing 65 mph and the engine revs at 2,500 my temperature gauge indicates 180-190 F. Since my car is breaking in I do not take it beyond 4,000 rpm.

The highest temperature I have seen was 220 F while stuck in a traffic jam on the causeway to the beach.

:iagree:

I'm with ya, we all have been waiting on Nissan to announce a cooler for this car that is approved for dealer installation and won't void the warranty. Any news is welcome.

John

I don't know the part number because during the interview they told me that there is already a nissan cooler available so I presumed that there is one already. Maybe we can ask the dealerships but I will see if I can get hold of the Senior Engineer that told me. I was in the Regional Corporate Office of Nissan in Costa Mesa California for that interview in fact I was with another Z owner from Whittier if he is a member on this forum......

As far as anyone knows (unless you've just heard about something new) there's only one cooler from Nissan (and it's a Nismo, part # 21300-SS370), which is $750-ish+ depending on the markup at whoever you buy it from, has a larger Setrab core than the 19-row we've seen in some other kits, but no thermo plate.

Is not having a thermo plate bad?
