IMHO all of you guys over here are exceptionally correct with all your analysis, Laws of Heat transfer and research data what else?..... that is why I love this forum.

Lets not overwhelm OP with technical data which might do two things...
1. We can probably scare him/overwhelm him to think he just bought a highly sophisticated machine that need all this things to make his car perform to a level that he even doesn't want to go through in the first place.

2. We can influence this guy to go with us in the Dark Side of being highly anally technical and damn obsessed of making the Z a super car which most of us would want to do. Burn the money away for the LOVE of performance. Nothing wrong with this its just a matter of choice and preference.

Going back to OP's question if you do not drive your car hard like us over here BIG Boys and all.
Then save yourself with the money and enjoy the car as you do not need the oil cooler.

But then if you want to go a different path just like in the movie MATRIX when you want all possibilities will be on your hand then choose between the blue pill and the red pill....Your choice buddy.

Either way you are welcome...Just be ready for a HELL of a RIDE!

BTW dont forget your credit card...lol

The problem here is, the engineering and observed data don't jive with your hypothesis :) Yes heat transfers, but the rate of transfer is vastly different across different materials and states of matter.

Heat soak isn't going to occur to the point of pulling significant timing. Simply measure IAT from a readout to see exactly what is going on. If you are stuck at a stop light for a few minutes, IAT may creep up a few deg F but once you start moving its back to ambient. The intake is not hanging on top of the block.

The thermodynamics here are not much different from car to car. Air temp is going to matter to fuel/timing. If folks buy an oil cooler with the expectation its going to improve performance on a street car, I think that's a misinformed purchasing decision. :tiphat:

spot on. I have the tools to do a test, which I did, oil temp doesn't have direct effect on engine performance. my car made the same power at 200 vs 270. just stick an electrical tape to the gauge and you won't think twice about it

270!? :eek:

But thanks for posting that you did the test :tup:


No way on electrical tape. I Would rather know when my oil temps are reaching too high and I Should Stop or cruise in higher gear.

I still don't understand why some of you guys are saying oil coolers are bought "for the sake of Modding." I'm pretty sure its for the sake of protection. I would Like to see proof that running your engine at 220-240 is better than 190-210.

Not better, it just won't hurt anything. That's why limp mode does not kick in until 280* because you won't hurt anything till it gets hotter than 280* for an extended period of time.

280 i think is when it limits revs to 2000 or something. Doesn't 260 degrees limit revs to 5000?

KaienZ34 07-31-2012 06:29 PM
According to the manual limp mode kicks in at 280* to prevent any damage. I don't remember anything about 260* but it could be in there.

I think forum members mentioned it being two stages. first limited revs then full limp mode.

Zoren 370 07-31-2012 07:38 PM
Is ambient temperature makes your ding a ling? LIMP???
Kinda notice since its been hot in here in FL my dragon seems to be always on LIMP mode. Now smart guys how does physics come into play with this or it just plain physiology or plain ergonomics?

Would wearing a satin brief would apply like having an oil cooler also?:gtfo2:

Noob: Should I get a 370/ oil issues
 
I am trying to decide if I should get a 370z or not. I currently have a 2006 WRX and was all for getting a 2009 or 2010 370z. After reading more and more on the oil temperature issue I have stepped back and I am rethinking my decision. Basically what i am asking is should I let that stop me from buying a 370z? It will be a daily driver but I still get on the gas and love spirited driving. I love my WRX and just don't want to buy a car that is going to have a bunch of maintenance problems. Thanks in advance for the help and advice.

Upgrading for the track is different than maintenance, but money is still money.
An oil cooler is what you need on earlier models for sustained spirited drives.
From my experience the 370 is better than a WRX at the track.

Good luck

Dr3ww3rd 09-22-2012 10:50 AM
Well I don't go to the track, just drive fast sometimes and love taking sharp corners with speed. Another question I forgot to ask is do the oil coolers fix the problem completely? Also do they ever over cool the oil because I know that is just as bad

Mikes350z 09-22-2012 10:55 AM
I daily drive my 09 Z and do spirited runs a few times a week. Oil has never gone above 230 even in the dead heat of summer.

Oil cooler is an easy and decently inexpensive fix. Since it is a DD most users place a steel cover over the oil cooler to prevent it from operating, thus protecting the car from having "too cool" oil in the winter months.

Oil should not be a major concern stopping you from buying a Z. If its your biggest worry, you should have bought one already.

Good Luck.

if that's the only thing that's holding you back, just get an oil cooler.

they're about 5 bills, and relatively cheap for a little piece of mind.
