sup guys, just wanted to know your theories of breaking your car in. i recently got a new car and it's my first new car so i wanna know how i should break it in properly. i only have 9xx miles on the car.

i've heard that i should drive it to 1k,2k and 5k miles, so im just confused. if this is a repost and there is another thread please link me because i couldnt find one.

 

I thought break in stops at 621 miles?

 

Please use the search feature next time.

Just look for all threads with the key words "break" and "in" in the title.

There are innumerable threads that cover this topic.

I've searched the key words for you this time, so fish out the topics you want to read.

They always have break-in guidelines in the owner manuals of every car I've owned.

 

for the first 1000 miles, keep the revs low but varied meaning don't rev it upto 4,5,6 grand. also don't cruise, don't keep a steady speed and keep the speedo varied but gentle. Change fluids at 1000 miles, though lots of people, including the manufacturer's recommendations, don't favor this.

 

sorry, i thought i did search those but i guess not. thanks

 

Oh yeah, I forgot to chime in here.

I pushed the pedal to the metal since day one, not just because of the fun factor, but because a lot of car gurus believe that is the true way of breaking in an engine.

But I always made sure that I only did WOTs after the engine was warmed up, and I varied my range in RPM levels.

From what I've heard from experts, this is the only way the engine parts will properly seal.

If you don't follow that method, you will supposedly lose a lot of potential performance of your engine and meet lots of problems in the future.

Also, the ECU learns your driving style in the early miles of your car.

So if you are gentle to your accelerator, your car will lose more potential performance, compared to an identical but properly broken in engine.

Yes, you CAN reset the ECU at any given time, but I wouldn't want to go through the hassle of trying to "train" my engine all over again.

Anyways, the other 50% of people will say take it easy and follow the manufacturer's suggestion.

But my theory is 'if you run your car like a wimp, it'll always run like a wimp.'

 

FLOOR THAT ***** from the Dealer's lot and leave some black rubber dust on their face....

 

yea that. Hard break in FTW!

 

+1!

This is a more recent belief but one I agree with.

 

Auto manufacturers don't formally require a 1000-mile oil change mainly because of the way so many people complain about having the slightest inconvience, but it is STILL a good idea. Metal particles and and other debris accumulate in the oil during the first 1000 miles, and the filter only gets out so many of them....not them all.

I would not go the normal 3000-5000 miles with a brand-new car.....after the first change, THEN, yes.

 

I don't know who these "experts" and "gurus" are that you are quoting, but the people and engineers who DESIGN engines for the manufacturers......and the people at the manufacturers who have to stand behind their warranties if the engine wears out prematurely........say otherwise. The 4000 RPM limit, no-jackrabbit acceleration, and no heavy towing for the first 1000 miles is put in there for a REASON.

 

.. R T F M .........

 

Pick up a copy of Hot Rod, Car Craft, Chevy High performance, Fast Fords...........should I continue?

 

OK, fine......go ahead. It's your car, your engine, and your money. Just don't complain if it ends up burning oil prematurely.
