Maybe we go bleed it see if that fixes the problem, and just out of topic what oil temps are you guys getting

Majestik

Rarely goes above 90

90-95 usually and i think i've seen 110 when thrashing it?

tao168

Yeah my stays around the 90 mark even before tt, it was sitting at 110 yesterday at idle

Dammit! I fly down on Monday! I miss out!! im there until the 11th July though Ill be skiing from the 5th July...

Perhaps u should make the cruise the 3rd July.... just for me hahahah and ill just ride in the TT with Tao to keep an eye on his oil temps. hahahha

I have had my car for 2 weeks now and I see temps ranging from 90-110 degrees depending on driving, traffic and weather conditions.

I would really like to install an oil cooler but dont want to void the 3 year warranty. I dont understand how nissan have designed a naturally aspirated car that can overheat, it really is unacceptable.

I have an evo 8 and after all the track days I have been too it has never overheated. It does have an oil cooler from factory but the car is also turbo charged which would produce way more heat.

Well I'd have been looking for you but your car hasn't been on the road... thats crazy though... although I've seen quite a few driving around the area....

Oh and thanks for cruising without me in the country.... how quickly you all forget about me...... sigh

Majestik

You're in bloody Greece man!

Cyprus now buddy... get it right..... Still I'm considering never coming back after this cruise....... I'll just ship the Z up here..... still haven't seen any by the way.... but in Cyprus today a Veyron drove past me.... sigh.... what a head turner...... there are also a whole bunch of f430's and bentleighs... just no 370s

Tao, you might want to consider an oil cooler AND a sump extender to permit a larger quantity of oil to help manage temperatures.

When I first took my Zed out on a closed road for some serious hi-speed driving (I participate in a number of closed road events at Sandown, Philip Island and other places where we can use our cars to their design potential without the risk of Inspector plod seizing our cars), I hit oil temp problems straight away (within 4 laps actually - less than 12kms). If the oil temp rises above 137DegC, the ECU puts the car into limp-home mode (<4000rpm rev limit, cuts back on ignition, blah blah).

As a conseqeunce, I have had a Stillen oil cooler kit, and a sump extender kit fitted.

Despite what a Nissan dealer may say, this will not invalidate your new vehicle warranty, rather, you need to be in a poisition to confirm that the root cause of any incident is not related to these additions - the law is quite clear on this point, so you simply need either to have confidence in your own ability if you fit these yourself, OR engage a reputable automotive engineering shop to fit them for you.

In any event, as soon as you start to use big revs, that involves the cam tricky-gear doing its thing (which is oil pressure actuated), you start to subject the oil to a greater workload ... there are lots of posts on this subject.

Bottom line, you are safe for "normal" driving unless ambient temps are really high (well over 45 degC) AND you are flogging the guts out of the car - either really high average speed (not sensible in our nanny-state in Victoria and probably the rest of Oz), or you are attempting to break you own personal record on the climb up Mt Buller for instance.

Without the oil cooler, the highest temps I saw last summer in normal driving was 115DegC, which is a bit hot, but well within tolerance. The minimum specification oil in the book can run up to ~140DegC without too many problems (and hence this is why Nissan has programmed limp-home mode into the ECU at 137DegC oil temp). Using a high quality fully synthetic oil is cheap insurance in my view, as these oils will tolerate higher temps, and given that I take my car out onto a closed road to use it at the upper end of its design limits regularly, I have chosen to fit an oil cooler and a sump extender to permit a little over 6 litres of oil inside the engine) - all of which is designed to resolve the design flaw created by Nissan manufacturing the vehicle without an oil cooler in the first place.

Those with a 4-wheel drive bent might be aware that Nissan produced the first version of the 3.0 turbo diesel with a sump that was too small, caused oil temps to rise and eventually a hole would burn thru a piston (part of the cooling in this engine comes from oil sprays up underneath the piston to remove combustion heat). Since the sump was too small, the oil overheated and the piston ran too hot and melted a hole ..... solution was simple, extend the sump and put more oil into the sump, and use a larger oil cooler. There is a lesson here for those of us that use our Zed's at the upper end of its performance envelope ....

Thank for the insight, we had an oil cooler mid build as a lot of plz had oil temps as a stock car. I just received a call today to pick up my car, Maybd going to test it for a couple days and see what's going on. From what I heard it was just a bleed problem. I will ask indepth what was the prob yesterday. But can't wait to try it tonight.

Majestik

Great news for all!

So can I take that as 100% confirmation of your appearance on Sunday?
