PROPER ENGINE BREAK IN PROCEDURE

PROPER ENGINE BREAK-IN PROCEDURE.
There are many articles out there on the proper engine break-in method. Even your manual & dealer state to 'take it easy and keep it under 3,000rpm". I have found a very well known article that has generated A LOT of buzz over the years. This has proven to be a serious head-turner and its good reading.

I tend to agree with this procedure and have used it myself on my race-bike. 14,XXX miles and still going very strong.

As taken from this article:
These same break in techniques apply to both steel cylinders and Nikasil, as well as the ceramic composite cylinders that Yamaha uses in it's motorcycles and snowmobiles.
What's The Best Way To Break-In A New Engine ?? The Short Answer: Run it Hard!
The best method is to alternate between short bursts of hard acceleration and deceleration. You don't have to go over 65 mph / 104 kph to properly load the rings. Also, make sure that you're not being followed by another bike or car when you decelerate, most drivers won't expect that you'll suddenly slow down, and we don't want anyone to get hit from behind!!

SO WHATS YOUR BREAK IN METHOD!?

This is an interesting discussion topic, thanks for the link.

I'd just like to add that trying any of these techniques would be at your own risk. If in doubt with anything, always default to the manufacturer's recommendations in your owner's manual.

I've never understood why the sales people aren't encouraged by the manufacturer to point out the importance of break-in to new buyers. I am pretty sure the vast majority of vehicle owners have no clue that a break-in period even exists for the vehicle. Granted normal city driving is probably the best for break-in, but I know people who purchase a brand new vehicle then take it on a long road trip/family vacation with cruise control set basically the whole time - not good at all.

its all about liability. they dont want to tell the average consumer to go and rip into his new engine.
that car will come back with either an accident, or with a blown piston rod through the block by some idiot who continuously red-lined his car lol

Even days before I purchased my Rogue I was trying to find the best method to break-in the engine of my car. I read a lot of articles, forums, posts...I followed Nissan's advice and did whatever they said in the manual. Now, after 13 months, I learned that as long as I have a CVT transmission I can never accelerate like a regular AT or manual transmission car. The only time I see engine real power is when I press the overdrive button and turn it off. Then I feel like I am driving a new car with a young engine.

If my next car will be a 0 km one, I will definitely replace the oil after the first 1000 km, to remove all the metal parts and pieces.
