Is there a break in period for the Z?

AK370Z

Everyone has their own way to breaking it in. Some drives it like they stole it from the dealership, while other like me, follow the 1200 miles rule. I am a firm believer of following directions of the highly knowledgeable Nissan Engineers but that's just me.

Here's what Nissan USA want you to follow.



58,000 miles and no problem yet :knocks on wood:

I did my best to following the instructions of the break in period. It took a lot of self control but it didn't take me all that long to get to 1200 miles. Within a month I was driving it like it was meant to be driven.

It's not the engine you need to break in. It is the clutch and brakes.

its not jsut test drivers. Workers are known to floor these ***** cause they dont give a ****.

And also they put in regular gas all the times, so its always good to drive off the first tank they give you.

The best break-in is keeping it at 7500rpm steady for as long as you possibly can at gyrating speeds. over 125mph a serious+

Go 4 the gusto bud.

Shove some potatoes in the exhaust pipes and rev the car. Don't know what it will do but should be interesting.

I half way followed the break in period for my automatic 2003 and 2008 Z. Never had a problem. The Infiniti G37 has the same engine. I got down hard shifting it and running it up to almost red line. I smelled something buring so I have not shifted it since. This was done when it only had a few miles on it. So, I am not going to run my new Z up to redline till after the break in period.

You will spend hours reading opinions on this. Most new engines are bench tested from the factory so the initial 'break' in of rings is mostly done given the tighter tolerances of modern manufacturing.

The Nissan recommendation is conservative. Personally I feel the best part of it (and consistent with other manufacturers) is to avoid steady state operations, i.e. cruising at 3K for an hour.

Vary the load on the engine, which implies varying the RPM load. You don't have to bury the throttle to get it above 4K, but IMHO its good to stretch the legs of the RPM range once warmed up. Sure you can get plenty of driving done below 4K but pushing to 4500, 5000, 5500 as you progress in the progress through the break in period is a good thing.

I have only broken in two new cars myself. First was a high performance honda which I did take on the Highway a bit when young. Next was a 2002 WRX that I very much broke in by varying load for 500 miles or so. Honda was sold at 140K, the WRX has 125K and still going. Both barely used any oil between 7500 synthetic changes.

Rest of my cars have been pre-loved so I have absolutely no clue how they were used. 2010 Z and the 06 Cayman.

We drive both of them with gusto.
