Reluctant to purchase 370Z
 

My 2006 350Z has 75,000 miles on it and has been trouble free. While initially it consumed quite a bit of oil as evidenced by black exhaust tips and rear fender, I did not have the motor swapped. The oil consumption stopped on its own at around 30,000 miles.
I love how the 370 looks, I'm just put off by this oil issue after sweating it out with my 350.

Same with my '04.5 Touring Coupe, Mag'; it's just too reliable to risk getting rid of it. You've certainly put mucho miles on your '06 Z, dude. My '04.5's only got 24k on it. Then, again, I live just 9.5k from work. So far, the only thing I've had to replace is the driver's side power window motor. Can't complain.

i'm quite disappointed i cant get to the top speed without hitting maximum oil (for me thats 126c) on the car. considering the temp was stable at normal speed before this, this is quite crap for a sports car. so instead of a normal speed limiter, us 370s got a speed limiter governed by temp.

just wondering, those of you who had 350Zs, did you have oil temp issues as well? (for those who installed an oil temp meter) or did u have an oem cooler to begin with??

Can you post a link to where MT said they "REPEATEDLY experienced limp mode with spirited driving with high ambient temperatures." I can't find it anywhere. Thanks.

<edit> never mind, found it. They also said that the couple they tested concurrently did not have the temperature issue. Therefore I say the roadster they tested had problems. Of course MT is the worst car rag out there................

Reluctant
 

The question about 350Z oil temperatures is a good one and a question I have also thought about. As mentioned I am in South Florida.
My car does not have an oil temperature gauge, so I have no idea what temps I have been running.
I have 75000 miles on the car, and the motor still pulls nicely (at least by the seat of my pants). I have the car serviced at my local Nissan dealership every 3000 miles or so.
I previously owned a 1987 300ZX (non turbo) that had over 100,000 miles and had absolutely no mechanical issues.
A few other questions I have:
Does installation of an oil cooler on the 370Z void the warranty?
Does the G37 have similar problems?

Thank you

I guess you could have your Nissan dealer do a factory install, no warranty issue there! But it ain't cheap. :rolleyes: I'd have to guess that an improper install could void a warranty, though. If you want to do a DIY, I recommend reading Modshack's DIY he posted here.

Not necessarily true! I questioned my dealer about installing the Nissan oil cooler and of course they said no problem. However when questioned on the warranty implications they were non-committal.

Oil Cooler
 

I also have spoken with Royal Palm Nissan's Service Manager in South Florida and cannot get a straight answer as to whether or not the warranty would be voided despite a dealer installed oil cooler. I am definitely not mechanically inclined enough to install it myself.
How much weight to the car does an installed oil cooler add?

Around 5 lbs.

Oh, and check out what happened with this guy after he installed an oil cooler on his 370Z! :rolleyes:

I just wanted to make it 1000 replies

Read the OP. it explains Nissan's viewpoint on warranty.

Believe it or not, I'm very very picky when it comes to cars and for some reason this oil temperature issue doesn't even bother me. It's nice to have reminders from Nissan about how fast you are driving a car. The higher temperatures cause people to slow down if they had been speeding. Most Z's that are sold will never see the track anyway. It's cooling system is sufficient for the public access roads but not for drag racing. Fine by me. I'm not the one to encourage unsafe behavior in public spaces anyway. Why should Nissan? Once that oil climbs above 300 degrees it is an indication that you are simply pushing it too hard. You can get an oil cooler installed as aftermarket but it would void the warranty. How do you know Nissan didn't plan this to cover their own finances when it comes to warranty repair work from people abusing their cars.

These are some really wreckless speeds that are unsafe for public roads and it puts many many innocent lives in danger. Let's not forget that the Nissan Z is the worst offender for getting traffic moving violations and car wrecks. It's still a great car though. It is just that it has the tendency to attract a certain crowd that causes it's insurance costs to rise up well above normal.

A Lotus Elise is a better track car in my humble opinion. I would get the Z just to drive around town but keep a beater car for groceries getting and bad weather. I don't want someone hitting their shopping cart on my aluminum bodied Nissan Z. Aluminum is weak and dents easily.

Think about this for a minute. If a car that weighs 3,300 pounds with a 332 horsepower V6 engine is overheating even though it is running as designed; This goes to show that someone is driving too fast for even the best driving conditions of dry roads, daylight and 100% visibility. Just drive normally and the oil temperature will stay within normal limits.

You get what you pay for. This is no Porsche 911. But it is still a fine car. You treat the car right and the car will treat you right.

If you want to drive faster than 80mph you should just get an airplane and learn to fly.

anyone know how accurate the speedo is?

On what basis do you make this statement? Do you have some official statistics or something showing that, say, for every 100 Zs, a greater number of them have moving violations and accidents compared to any other make/model on the road?
