"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 500 km (300 miles):
• 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.
• Avoid unnecessary quick steering, abrupt
braking and driving on poor roads.

500 to 1,000 km (300 to 600 miles):
• Avoid rapid acceleration in a low gear (1st
to 3rd gears) with the accelerator pedal
fully depressed. Depress the pedal slowly.
• Avoid unnecessary quick steering and
abrupt braking.
• Drive with the suspension setup switch in
the COMF mode to allow more suspension
stroke.

1,000 to 2,000 km (600 to 1,200 miles):
• Drive with the engine speed kept relatively
high, shifting is recommended between 1st
and 4th gears.
• Avoid unnecessary quick steering and
abrupt braking.
• Drive with the suspension setup switch in
the COMF mode to allow more suspension
stroke."

Ah yes, but what does "engine speed kept relatively high" mean?
Some have taken that to mean at the higher end of 3.5k,
and others have taken it as 7k gently.

I have taken it as higher end of 3.5k, and give it a squirt now and again.

(Appologies for spellings or whatever, I've just got back from a boozey lunch. And no, it wasn't free). :)

well when i spoke to simon croft at goodwood he said it was best to drive the car hard after the first part of the run in process (i.e. after 600 miles?)

well one advantage of going to JFE is that they will do the work for free. Another is that they have the software to make any alterations that are necessary. We have been told that although European law dictates that warranty is protected as long as correct parts are used by trained technicians whether at nissan or not......we have to get the free optimisation services done at the HPCs to keep the warranty. Each of the HPCs have sent at least one technician to special courses run by nissan on GT-R servicing

the cars haven't been around that long. i'm not sure who would have more experience. the optimisation service doesn't really seem all that complicated as far as i can tell

If you buy a car with say 4000 miles, can you tell how it was run in? Will the telemetry all still be there - either in-car or by reading the ecu? Just seems like someone who sells the car very early has possibly had rather too much fun in it and if their intention was always to sell early, how careful are they likely to have been? Depressing to think a car with 2000 miles might already be a financial time-bomb.
