old news bro. I agree with it. Seems to be a good idea to break in that way.

 

[fragchild]

One thing I never understood is why if it's so important for the longevity of engine to be broken in properly, why don't manufacturers break the engine in before it ever makes into the car? That would take all of the guess work and confusion out of it.

If I remember correctly I believe Triumph puts a 100 miles on their motors before they make into the frame of the bike.

They do break the engines in before they make it in the car. That is why its stupid to even think about so called break in periods now days. I still went easy on mine for a bit when it was new. You arent going to convince me to go hard for a break in so forget it.

i Did it and I dont complain info is for new members its common question.....

Great article wisnisPl! That's almost exactly how I broke mine in and it's been running great ever since 17k miles and running hard as hell daily! All the talk about babying it made me giggle.

it seems logical -- but why don't the manufacturers recommend this?

Because some people don't comprehend the difference between "break it in hard" and "completely beat the s*** out of the car and break stuff". Then manufacturers are stuck fixing all the broken crap under warranty.

They don't want to have to deal with possible lawsuits. Owners might try to blame speeding on the manufacturer because of their recommended "break in" method. I really don't know, that's just my logic. Another thought is that perhaps they really don't know for sure and they haven't done extensive testing and or just going off of popular belief / myth.

I've used the Mototune Method as well on a fresly re-built forged piston'd F2T. Consequently, it's pulled higher compression #'s than ANY F2T I've ever owned, ore re-built

Liability.

Just imagine, if God forbid, something were ever so slightly wrong with the motor from the factory that normally would not be a problem for many thousands of miles (read possibly out of warranty period) that were exposed in the first 1k miles by the Mototune break-in method. I'm sure you can imagine the s*** storm when people flocked to the dealer looking for a warranty.

Rather, they say be gentle on it, it's fragile. Not to mention that few people that buy a car, performance or otherwise will have the focus to do the procedure right, and then change the oil when they should.

FWIW, I have heard on more than one occasion that Corvette motors are run up through their RPM range under load before leaving the factory.

there's a chrysler plant a few miles away from here where they make the durango and the chrysler equivalent. what they do is right before they get off the assembly line the engines are started and revved the s*** out of. if the engine can't stand it, the vehicle is sent back to get a new one

apparently the average bad apple is like 1 to 1000 or something, so at least they find the problem child before they make it out into the open

They should've at least tested the turbos for our cars appearantely.

That is what motoman is totaly against. He says DO NOT rev the engine while it is unloaded. I'm glad I never bought a durango.

its about money...all car companies are trying to save money on each step of production.....

 

[Super Unique]

from the sounds of this I broke mine in good LOL
couple of hard pulls the first day..... I know it's not using any oil for 3k miles. Was still full when I changed it the first time.

Sure but in this case its seems they might have lost money.
