I just got my 05' 6mt Coupe (Black/Black) and it's frickin beautiful. I've searched the forum in regards to the break-in period (I know bout the 4k Rpm limit, altering speeds/rpm, towing, etc.). But my dealer also said that I should keep it below 120 kph (75mph). I can easily get to 120 kph while stayin below 4k RPM. Does that mean I should be able to go faster then 120 kph during the break-in period? Sorry for the long-winded post.

 

I wouldn't pass 60mph...

 

just don't pass 3K RPM

 

On the other hand, I believe in the theory that you should drive the car the way you always plan on driving it. In other words, don't baby it.

As soon as I drove off the dealers lot, AND warmed it up, I was revving all the way to 7k, and enjoying the car. The key really, is making sure it is warmed up.

But hey, you are welcome to believe whichever break in theory you want. Have fun the first 1000 miles driving like a granny...

Haaaa that's so funny and true....Granny !!
I m still on my break-in period..and I have 2300 miles on my G now.
I hate to see those corolla, lancer, or civic drive faster than me
even tercel is laughing at my snail G !!!!!

but after 3000 miles....i'll show them my revenge!!!! >"<

 

My dealer said nothing about limiting my 05 5AT to 4000 rpm, but did tell me not to use the cruise control for the first 1000 miles.

 

I took mine to redline about 5-6 times during the first 1200miles, and used cruise control for 40 miles. So far no problems. No burning oil, and I switched to syn at 3K. I think the car will handle anything you throw at it just fine...

Btw, the first 1200 miles took me all of 10 days to reach it....

 

I was told not to go over 50 mph for the first 1200 miles and to keep it under 2000 rpms.

 

Dave,

Any thoughts on why Infiniti/Nissan would advise the new owner to not exceed 4K rpm? The "Spoilsport Syndrome?"

 

I read the manual and am following what it recommends. They engineered the car and I trust their more than I trust any input from "shade-tree Joe."

850 miles. Tick tock..

 

2000 rpms? Is it even possible to drive the car properly? I was told nothing from my dealer but still used my own caution for the first 1200 miles. (kept it under 4K RPM but I did drive as fast as I want)

 

I don't know where all these people are getting their information about 2000 rpms, keeping the car under 50 mph, and etc. READ THE OWNER'S MANUAL!! Don't accelerate too quickly, keep the RPMs under 4000, that's about it. Also, any engine builder will tell you that the proper way to break in an engine is to run it through a series of RPM ranges in a set sequence. Engines broken in on Dynos are broken in that way, and it only takes about 30 minutes. When you are breaking in an engine, the main thing you are doing is seating the piston rings, which doesn't take much at all. Of course a manufacturer is not going to tell you to take the car out and flog it because if someone recked, they would be held liable. To make a long story short, follow the owner's manual, or research proper engine break-in on the web, you'll be surprised at what major performance engine builders recommend.

 

Couple of reasons in my opinion:

Liability: It is a high powered sports car. They would rather have people get used to driving a high(er) performance car gently, rather than jumping right in, swinging the tail out and totaling it in the first 10 miles. Same reason why understeer is built in to most cars, rather than oversteer or neutrality.

Tradition: Thats the way cars have always been broken in. It made sense back in the day of poor machine tolerances, randomness in constructions, poor quality oil, etc... Nowadays, in the world of tight tolerances, high performance oil, etc..., it is not necessary, and in the opinion of some people (myself included) it actually is not so good for the car in the long run to break it in gently.

I'm not prepared to give the technical arguements for this, but from everything I have read about it, I am convinced that driving it like you stole it, for the get-go, is the best thing you can do for your cars long-term performance.
