I have no idea what to follow but I worry less about the car's engine and other systems and more about gas...hah...but then again, I have to ask myself...why buy a sports car, albeit a luxury one if your not going to drive it hard, right?

 

drive it like u stole it from day one!! it has been repeatedly proved that a motor ran hard from day one will be stronger than those following the owner's manual.
of course, no one is sure that the ran-hard motor will last as long as the nicely broken in one...but who really keeps their car that long anyways? it may shorten the life of the engin a lil bit down the road..say from 120K to 110K?? i dont really see a problem with that, unless u wanna keep ur car forever. i know most peeps wont..cuz there are always better cars comin out down the road! haha...

 

Actually, it's be proven that cars that are broken in tends to break less and don't burn oil like the ones that are driven hard from day one. Like I said, it was an article in Motortrend or Car and Driver. They take cars out when new and drive them hard for about 40K miles. Anyways, trust what you want and do what you feel. :-)

 

i ran my car hard from day 1 raced it and all..never folowed the "break in period"

 

At 450 miles, still keepin it below 4k rpm. went over a little a few times, but generally keepin the revs down

 

There seem to be two thoughts on the subject:

1. There are websites that describe different ways of breaking in a car. Some of them state that the car will be stronger, have more HP, etc if you break the car in by pushing it hard.

vs.

2. Then there are the Nissan engineers who desgned and built your car. They state that you need to take it easy (outlined in the manual).

You can believe whoever you want, but keep the following in mind:

Anyone can say anything they want to on a website, and include pictures and dyno charts "showing" that they are correct.

You may want to verify that the VQ35 engine has the same characteristics as engines that are "proven" to be stronger after being broken in hard.

 

how do you reset the ECU and what does that do?

 

I am not endorsing either method, but do you honestly think Infiniti would tell you Go out and beat the chit out of the car to get the best results out of the break in even if it was true? Imagine the liability!

 

Well, I don't think that statement is exactly true. I believe Nissan can say nothing and let the driver decide but the fact is, they said to break it in slowly. Of course they won't say to go redline the car but you guys are making it sound like they either say "Go redline the car before 1000 miles" or "Take it easy for the first 1000 miles". If they had left it all out, I say it would be fine to drive it hard. Well, from past experiences from friends who drove their car hard from day one, all I can say is how much do you expect the car to gain in HP from being driven hard from day one as oppose to taking it easy and not worry about problems down the road? I myself took it easy from day one but did set the RPM at 4000 and rev'ed it up past 5000 once a week and so far, no problems.

Just a side note, I wonder how many of the people who had tranny problems and clutch problems on this board drove it hard day one and who didn't? That would be a good post to find out!

 

This is my sentiment exactly. Infiniti would never tell you to drive the sh*t out of the car even after the break in period. If we're talking about the G35 and experience vs. what experts claim I'm going to go with experience. Have we seen one post where someone drove their car hard from day one and ended up dissapointed? no, matter of fact they have been pleased with the results.

 

I ran my car hard since day 1 and I did see a higher number then most other stock G35s on the dyno before I had my supercharger and I never break in any of my cars they are all broken in from the factory if you ask me. but thats just my opinon.BUT I also did see less gas mileage then most other G too so I assume base on my experience if you don't break it in you"ll see better performance and less gas mileage and if you did break it in it would be the opposite result.

 

If a slow break in was VITAL it would be easy enough to program the rev limiter to be set at 4000 rpm for the first 1000 miles. This is about a few factors:

- 1) liability. if there is somehow a faulty part that's gonna pop right away Infiniti would much prefer it happen at half throttle rather than full gun. This requires a break in period cos that part is gonna take longer to pop when driven that way.

-2) image. Start having things **** up on your car with 120 miles on it and you're gonna get a bad name.

-3)comfort. If it makes you feel better to baby it - then do it. A little foreplay never hurt anyone - it just makes the full on banging that much more exciting.

I personally believe that the precision with which motors are built nowadays combined with better lubricants mean the break in period isn't as vital as it used to be. Remember, we have a 6 year powertrain warranty that Infiniti shells out for. If they thought slow break ins would lower repair costs they would fix that limiter in a hurry.

Anyways thanks to that 6 year warranty and a 39 month lease you know the back of my gas pedal is gonna get real familiar with my carpet!

 

Esentially you'll have to go with what you feel comforatable.
Nothing any one says here will give you a conclusive answer.

I have a method that I've used for a long time & have had good results.
Maybe it's the method maybe it's just good luck, who really can say.

 

Well, you certainly know how to build a good LOOKING car so let's hear it...
