I agreee but we were talking about the breaking period NOT the warranty period.

Believe me that I will drive it like I stoled it after the break in period.

What break in period? Is there anything in the manual that says how to drive it for so many miles for a break in? If not then.....

drive it like normal.

Don't listen to all the kids on this forum who's Daddy or mummy bought them a nice car. Let the engine, transmission etc gently get to know each other and the most important thing change the oil at 1000km, then again at 5000km. By this stage the parts should have married well together.
These kids who drive them like they stole them (what an attitude) are probably going to be traded in , in two years anyway so what do they care. Too many people nowadays think of themselves and to all the retards that post back against me...stuffya.

Thirty to forty thousand dollars represents a lot of hours of hard work to an old fashioned OldGuy like me. So I'm being careful with my new Z and I'll never "drive it like I stole it," even after break-in is over.
Please don't confuse my maturity with old age...I think its just good sense, unless you have money to burn. Not many folks I know do these days.

I take good care of my car, but I'm certainly not concerned about my car being pristine 10 years from now. The next guy can either choose to buy it or pass.

I doubt anyone can find legitimate evidence that following a break-in period versus driving aggressively from day 1 makes any difference. The web is full of heresay on this issue but lacks good research-based conclusions.

Treat your car the way you'd like to be treated and it will return the favor for years to come.....(this works for women too....:-)

I totally agree with “this works for women too”

I was reading the brochure on the GTR, and it says that they do a engine break-in running the motor for 1 hour to include a continuous 10 minute run at redline before the customer gets the car. This contradicts what their manual says to do with the 370Z. I know they are different cars, but shouldnt all break-ins be done the same?
Ive heard of folks saying that the reason they dont want you to run the car too hard during the 1st 1000 miles or so, is because if anything were to go wrong with the car, it would be in those 1st 1000 miles. And if your running hard and fast, you could get into an accident if any part failed, this would mean a law suit against Nissan.
I do know that your supposed to vary your speed frequently in order to put a load on the cylinder walls so that it breaks-in properly. Holding at one speed for too long creates hot spots in one area and the cylinder wall dont get broken-in properly causing oil consumption and bad compression. I believe the owners manual states not to keep the car at a constant speed during break-in.

This is from the GT-R Owner's Manual. Once again, those who designed, built and tested the engine recommend a strict and conservative break-in period, though this one differs from the 370Z after 600 miles. Disagreeing with the engine designer is a rather fruitless exercise, imo.

BREAK-IN SCHEDULE

NOTICE
Follow these recommendations to obtain maximum engine performance and ensure the future reliability and economy of your new vehicle. Failure to follow these recommendations may result in shortened engine life and reduced engine performance.

Please observe the following types of driving until the mileage shown below has been reached.

Until 300 miles (500 km):
. Do not depress the accelerator pedal more
than halfway and avoid rapid acceleration.
. Drive with the engine speed kept at less
than 3,500 RPM.

300 to 600 miles (500 to 1,000 km)
. Avoid rapid acceleration in a low gear (1st to
3rd gears) with the accelerator pedal fully
depressed. Depress the pedal slowly.

600 to 1,200 miles (1,000 to 2,000 km)
. Drive with the engine speed kept relatively
high. Shifting is recommended between 1st
and 4th gears.
