engine break-in contradiction

People also say that you get better mileage at 2-2.5k RPMs.. I say that you should prove them all wrong and drive it at 8kRPM all the time. You'll save tons of cash on gas.

ok so which one is right??
i guess i took my friends' advice and started driving to redline in first (the little light showed up indicating i was in the 8,000 rpm, which i did on accident a few times). is this bad for my engine??
i also heard get an oil change at 1,000 miles, or 1,500 miles or the 2,000 miles.

I did read a lot of the threads on this site about this issue.
and a lot of you guys contradict each other..
so i have no idea what to believe.

Which do you think is a better authority for giving instructions and recommendations on HOW to properly break-in an engine? Nissan themselves, or "a lot of people"?

Apparently words from strangers in the internet have more validity than Nissan themselves.

I would go with "a lot of people" as they are obvously smarter. A lot of people voted for the current President as well as the latest "American Idol". I personally think the intelligence of the masses is under-rated.

Power to the People!

Granted, the "people" who voted for (and watch) American Idol are girls from the age of 7 - 15 with access to cell phones and texting (yes I blame the parents).

Maybe we should ask these same children how we should properly break in our engine?

Based on the opinions I have seen across different forums for different cars and motorcycles, the more knowledgeable people seem to say this: break it in easy for longevity, break it in hard for power. I went with with a little of both. I avoided WOT and 6500+ rpms for the first 1000 miles or so, but still drove in a "spirited" manner around town.

Nissan obviously recommends a break-in procedure for a reason, but doesn't tell us the reason. The question is whether that unidentified reason - which, from a practical standpoint, is most likely for longevity purposes - aligns with your own goals. Sometimes it does, sometimes it doesn't. But arguing that the manufacturer's recommendation is the only correct/safe/best way to do something, simply because it's in the manual (and without knowing why it's in the manual), is a bit short sighted in my opinion.

Why would the manufacturer's recommendations NOT be the best way to handle THEIR product? I don't think I necessarily need to know "why" it's stated in the manual to follow. They're the experts. They're who I follow.

Now if I was an automotive engineer who did some testing on what results proper break in (under 4k rpm) yields, maybe I could question what they say. With how you broke in your car (1/2 and 1/2), what evidence do you have that you helped or hindered the longevity/performance/power/etc of your engine? Without proper proof or proper testing, any results you have are circumstantial. If you do have proof and did tear down your engine or did other forms of testing, I stand corrected and will fully accept your claim.

But until then, I will follow what my manufacturer recommends.

Break in? I think its bs. They test them at the factory. When test driving do test drivers like the car magazines break it in before they rip on it...no. let it warm up then drive how you want too.
