He drove it like he stole it down to one quart.
It locks up. So no coverage. He got what he deserved

How many miles did the guy drive before he took it back with one quart?

ok I may be naive, but is sticking with manufacturer "recommended" (emphasis on recommended) tasks ESSENTIAL to getting approved warranty work?

Don't get me wrong, of course I do all the recommended (and at times beyond recommended) maintenance tasks, but I did not know that you HAD to do these tasks to be granted warranty work?

very interesting

it had 9000 on it. but you could tell he had drove the crap
Out of it. Tires looked they had 50,000 on them

9600 miles and he doesn't change, or even check, the oil? Wow.

I believe if you don't follow the recommended maintenance schedule Nissan published they could use that to deny a warranty claim. To my understanding you don't have to do more than that, but if you see oil sparying out from the side of the block you better tow in the vehicle rather than continue to drive it.

Any good master mechanic can tell if the car was maintained or abused.

Manufactures are making engines with much higher tolerances today. Where cylinder clearances used to be in the thousands of an inch, now its in the ten thousands. Bores are rounder and straighter. There is know reason to baby a newer engine, it will actually hurt. You need cylinder pressure to drive the rings out onto the bore, which actually shaves the bore into a perfect fit. By babying it the rings will only rub and burnish the surface leaving a less then Ideal finish. So ... keep the revs below 4000 the first 300 miles, then drive it ... accelerate with meaning for the next 2500 miles and your all set. This is how all High Performance engines are broken in, and all engines today can be considered a high performance engine since they pull more power out then there predecessors ever did.

Just follow the user manual. The manufacturer is clearly telling you how it should be done and that's it. Anyone who has another method is just opinion and preference.

370ZGTR · 06-19-2012, 03:11 AM

for future Z owners, when breaking in your new Z, DO NOT drive it over 4,000 rpm for the first 1,450 miles (breaking period) or else...let me just say, new engine installed by NISSAN USA, warranty =)

So, what qualifies you to make this statement?

I love the contradictions in certain threads. Engine break-in? Nissan engineers know best so follow the owner's manual to a T. Wait, engine oil? Hell, Nissan doesn't know what they are talking about, you can use snake piss as long as it's 5W-30.

homeryansta · 06-19-2012, 08:15 AM

The break in period is for the clutch. Not the engine.

andre12031948 · 06-19-2012, 09:38 AM

People that know what it means would not rev a new engine to 8,000 rpm.
This is how I brake in my cars(I've owned over 25 cars). Accelerate slow, shift at 2,500 rpm, once in a while accelerate(in any gear)till about 4k & then lift foot off gas pedal. That opens up the rings & helps the rings get a great seal. Change break in oil at about 1,500 rpm. Just enough to break in engine & get rid off any loose material in the oil. I mostly always shift at apx 2,500 rpm. Except for passing or getting on the highway or racing, I never accelerate fast/rev high for no reason or stupid reasons like listening to my exhaust. period.

People that accelerate/high RPM often, will wear out their rings much sooner & put more wear on their bearings/all parts..

I have two nissans near 180,000 miles & almost burn no oil & oil stays clean.

Thank god you were here to answer the question...... a year later

You're missing the point. Break in procedures really provide no monetary gain for Nissan (unless you were to blow the engine I guess)... some people dispute that the ester oil is somewhat a gimick to an extent to drive service revenue at Nissan.

Not saying I agree or disagree but they aren't exactly apples to apples.
