Apparently you have not tried it. I'd throw some datalogged charts up but I don't think you'd get it.....:shakes head:

I was only responding to the risk of water. Everything in there should be weathersealed. I've driven many cars around without a hood. Some even during the rain.

I must say that too many of Z owners seem to blow things out of proportion. I am at 7500 miles with my 370Z, daily driver from early April and I haven't had a single issue. I even drove it on 900 mile trip without stopping to Miami without any issues. 110 degree heat 100% humidity in south florida and my oil temperature never reached 230 degrees (I was driving normally). I have the dealer change my oil at 3000 miles, and if I am to exceed I stop driving the car until it's changed. I use synthetic oil and never had to refill.
My only real complaint is that those wide rear tires with sport package create way too much road noise for long trips.

I have never had oil or any other issues, other then passenger window motor needed to be replaced on my 350Z as well.

I agree completely with your first statement. Many folks not only blow things way out of proportion but they are far too critical. I have noticed that some folks between the ages of 20 and 35 (I guess) seem to be under the completely mistaken and unrealistic impression that any car they buy is supposed to stay brand-new and not require any maintenance of the smallest or simplest kind despite their constantly putting the car through its paces on some race track or on the road on a regular basis.

These whiners are lucky they have been born in the later years (late 70's and and 80's) rather than the earlier years of the 50's and 60's when the laws weren't as they are in this day and age where just a mere wimper from someone causes the courts to over-react and eventually help with the forcing the car manufacturers out of business due to the numerous number of frivolously rediculous nuisance suits in the courts brought upon by the consumer's prima-donna valley-girl like reactions.

Now your one statement or practice where you stop driving your car when you reach the 3000 mile mark. This is absolutely NOT necessary to do. The fact that you use SYNTH oil in your car allows your oil changes to be extended from 3000 miles to 5000 to 6000 miles. So if you hit the 3000 mile mark relax and continue to drive the car until you get it over to the dealer to change.

Just as an FYI even the oils refined before 20 years ago weren't required to be changed every 3000 miles but rather every 5000 miles. And those engines ran every bit up to and passt 200,000 miles. This whole "change your oil every 3000 mile :bs: was osmething that had its start around the time cars became fuel injected and was really a push by the refineries to try to capture the dollars they lost during the mid to late 70's oil embargo. Through their partnership with the car manufacturers they together have managed to create and maintain one of the best and relentless propaganda campaigns over the past 20 years and have got the consumer completely buying into the crock hook, line and sinker.

The irony of it al is the oils of today are of such superior quality and engine protection over those oils produced prior to 20 years ago. If anything the oil changes should have gotten extended not reduced as they have historically become.

But like PT Barum said "there is a sucker born every day". Its just so happens thre has been two entire generations born that have bought right into the :bs: of the oil industry. Do yourself a favor and don't be one of them.

I know this from talking with master mechanics at various Infiniti dealerships.. also having close friends who work at the dealerships, helps..
^ 6 cars between March - June, were waiting on engine replacements... can't be a fluke. and when they check for OC, its supposedly similar to the amount seen with the Revup Motors.

Question:
-How would you fix a leak, when the problem with the revups were supposedly caused by valve overlap.. This overlap created a vacuum which would suck the oil via the guides and out the exhaust.
So how do you fix an inherent flaw in the design?
Do you think Nissan is going to issue a massive recall and loose millions?

I hope my information was somehow limited to those vehicles that I heard of.. but I would not hold my breath.

As the owner of an '06 OC 350, who did a lot of research on this, from what I could gather you are basically correct ......... vacuum suckout through the exhaust.

if the car was broken in 'easy' you may have a ring seal issue...break um in hard kids, helps the rings seal

I have this issue with mine as well just rolled over 10k and after the first oil change at 3000k the oil was gone within 3000 miles... enough of a loss with no warning light to make them replace the timing belt and gear.... 3000 miles after no oil showing yet again on the dip stick... I think this is a major flaw... taking in tomorrow again to get them to fix it... No car should have to fill the oil as much as you fill the gas tank... No warning lights saying its low nothing at all. Guess will be selling to someone else to deal with before the warranty runs out unless Nissan fixes the issues....

NYBladeZ 03-22-2010 11:20 AM

~4200 miles, no issues. I have seen as high as 230ish oil temp but upon checking the oil after cool down it is exactly where it needs to be. I drive it hard on occasion but not enough where it is abused, I also stored it outside for 8 months under multiple tarps. Only 1 oil change done thus far, I used Nissan Ester Oil, I know it's not required but why risk otherwise. I dynoed on a dynojet yesterday, I'm happy to report humbly that the motor seems healthy and strong. Not to add fuel to the "break in" argument, but I babied her for the first 1850 like the manual says, many ranges of revs and speeds didn't really hit redline a whole lot, maybe that helped...

Lynchmawb 03-22-2010 11:31 AM

As a side note I have owned a 2006 G35 I purchased brand new as well and no issues at all with not driving that car any different than I am today... Almost wish I would have kept it at this point...

NYBladeZ 03-22-2010 11:52 AM

^^ I met a guy this weekend, bought a new g35 went through 4 quarts every 1000 miles and Infiniti couldn't solve the issue

j.arnaldo 03-22-2010 01:10 PM

I just hope you live near the dealership...What a hassle, going back & forth there!

:iagree:

In the german z manual like most other german cars alow 10W40 (its ok). It depends on the temperature range you want to use the car. And the companys use a 5Wxx or 0Wxx into the engine to sell it in cold and hot areas. If you put a 10W40 inside it is also ok. If you use non syntehic oil throw it out earlyer. A 10W40 is also better for the hydraulic tappets (reduces ticking i dont want to explain)..

Every one with the 0Wxx 5Wxx oil will damm me now. But i wont care cause i know what the API Motoroil classification is worthy. Of corse you have to drive 20-30min before you can rev the engine high.. thats all (oil temp gauge).

For cold starts and hig rev the 0Wxx 5Wxx will help the speedy and impatient people a time (guarantee issue). But this oil is burned more cause its more viscous (reasoned ! 0Wxx Its always a problem with turbos rotary "gasket" and oxgen air sense pollution and the resulting dramas cause of intake with sensor pollution )

:tiphat:

P.S.: I do my first exchange after the low rev burn in with a changing to 10W40 Mos2 Oil (I can post the pdf temp issues for SAE classes from the german manuel if you dont believe )

Dont rev the engine high in burn in,cause if there is maybe some metal from production drill (chipping waste) in the engine not rinsing perfectly before mounting it together; so you will ruin it and the oil type didnt matter any more (dealer test drive cars with low milage..i did it too but not on my Z :bowrofl:). (its an aluminium engine so no magnetic will help in the oil stream ..of course the pistons floating surface is not out of aluminium)


All self educated Oil professors/popes can banish me cause i know oil threads are useless discussions in all kind of Forums (cause of no API/SAE knowlege)

so i will be quiet for ever ... this is my last and only oil post :ughdance:

Well I started this thread a few months ago & now I have about 10,000 km on my 370. Thankfully the oil consumption has abaited significantly. I purchased a VIP package from the dealer so you get free oil services (regular oil) for as long as you own the vehicle, up to 4 per year. I do pay extra to run Mobile1 - 5W-30. I'm consuming about 1/2 litre in 3,000 km. I do run this car a little hard sometimes.

Other than that I had the rear hatch springs replaced under warranty cause the thing just stopped popping open & you had to lift as you pressed the button. The clutch has also calmed down & is not as grabby as it was.
All in all I'm pretty happy with "Beyonce" -(stand 10ft behind a 370 & you will get the reference). Getting a lot more comfortable going sideways too.
This car is too much fun!

Thanks for responding to this thread.
