It seems to me like he's saying drive it hard.

the owner's manual says to break it in easy ...
Notice that this technique isn't "beating" on the engine, but rather taking a purposeful, methodical approach to sealing the rings. The logic to this method is sound. However, some will have a hard time with this approach, since it seems to "go against the grain".
The argument for an easy break-in is usually: "that's what the manual says" ....
Or more specifically: "there are tight parts in the engine and you might do damage or even seize it if you run it hard."
Consider this:
Due to the vastly improved metal casting and machining technologies which are now used, tight parts in new engines are not normal. A manufacturing mistake causing a tight clearance is an extremely rare occurrence these days. But, if there is something wrong with the engine clearances from the factory, no amount of gentle running will fix the problem.
The real reason ???
So why do all the owner's manuals say to take it easy for the first
thousand miles ???
This is a good question "

I went back and read the article and answered my own question. His instructions are to open the engine up at WOT in 2nd, 3rd, and 4th gears. That to me is pushing the engine pretty hard.

Yo Arm, Nissan acknowledged the feathering issue by a TSB that extended the warrenty to 24 months & 20,000 miles (or 30,000 with participation).
What tranny issue? Mine shifts like a fine swiss watch. If your having trouble with yours perhaps you need some instruction.

I have no problems driving a manual, but thank you for your generous offer.

[QUOTE=mwest300zx] But, I am a fanatic about changing the oil/filter on a consistent basis.
This is key in my book. ^
Ever heard the expression "drive it like you stole it"? My opinion and experience has been that you break an engine in the way you want it to run. For ex. Chevy truck at 95 MPH for 130 mi. I left the lot with 5 miles on it. Truck is still strong with a 165000 mi. on it. Thats a chevy, not a VQ! To each his own but I think you end up with a stronger engine braking it in hard. JMO
