It could cause pre-mature wear on some parts.

Experts say symptoms won't show right away, but down the road when
mileage goes up, thats when your car is going to start charging you
some maintence bills.

very good responses so far

this will help also. If any of you are mechanically inclined as you
say you are, you'll fully understand what that article is trying to
prove.

what honda do you drive by the way? I also have a honda.

I know exactly where you are coming from cosmosblau, you have no worries. You aren't keeping the car for the long run and if anything does happen, it's covered by warranty. Why Bother?

Let's just hope there is no "blackbox" info stored when the engine burns up at 30K...

Wouldn't that suck if they came back and said "Well, back in September of 2005 I see you were doing 5000RPM's when you only had 850 miles on the car... You caused this sir. You failed to... Blah Blah Blah Lawyer b.s."

From what I've been told the computer keeps track of max rpm and doesn't track date/time. I learned this from some early E46 M3 owners who had the rod bearing failure.

[325 Baller]

how long is this "break in period"? like a certain amount of miles or a certain amout of hours?

[F32Fleet]

Do a search on the internet for engine break-in, it'll provide some interesting insight to the whole thought process behind "engine break-in".

A old engineer who has 30yrs experience in engine design/NASCAR/Formula1 told me auto makers know most auto owners do not know how to properly "break-in" an engine and they don't want the liability of telling their buyers how to do it, so they came up with an acceptable formula for keeping oil consumption to a minimium while preserving engine performance.

Gentlemen... This is definitive...

Largely stay under 4.5 for the run in.
Zing it up a bit just to test it and experience that glorious noise.
Dont max it until after 1250m.
Then treat it very well and give it a regular seeing to.

Engines are like women.
Start gently and build to treating how you mean to continue.

I have a '99 Honda Accord. I love the damn thing. It's my first car, and all I have to do is check the oil and make sure it has water. You can always count on a Honda.

[lux.sh]

6th generation accord! Do you goto V6P.net at all?
I used to own 02 AV6. J30A engine was great despite the tranny issue.
do you have I4 with F series?

[ZenDriver]

Gentlemen... This is definitive...

How he hell is this definitive?

Does anyone here have ANY proof that all of the chickenbone throwing that is the "recomended" engine break-in procedure has ANY effect on overall engine performance, loengevity or overall reliability?

No, you don't.

Look, do whatever your going to do with your own motor, but stop prognosticating as though you have ANY evidence to back up what your saying. Aside from a boilerplate, throwaway line in the owners manual, there is little scientific evidence to suggest engine break-in procedures work one way or the other.

If BMW really wanted to make engines that lasted forever, they would fit a larger starter motor and have it spin the motor for 4-5 turns before the computer started injecting fuel and firing the spark. This would pump oil through the galleries and have it lubricating parts before the shock of startup hit. If've you've ever heard a McLaren F1 starting up, that is exactly what it is doing for those 4 chugs before the beast breaths fire...



Edited to add my standard admonishment during this debate:

NEVER RUN YOUR ENGINE OVER 3K RPM WHEN THE MOTOR IS COLD!

Is a dry sump system different in that it will pump oil through the engine before engine start?

Hi Guys....Here's my problem. I will be picking up my car in about a week and I'll be using it to get to work each day. But work is a 20 mile highway drive each way. How can I get around this? Maybe it's just a matter of me picking it up on a Friday and driving it all weekend?

No, never been there. I don't plan on doing anything to it, it's 4 cyl. anyways. I just use it to get me from home to work, work to school, and school to work; and on the weekends from _______ to fun

No worries, just don't count your highway miles for break in.

HRC - Hehe... but what if people find out? I'd be toast.

I'm not saying whether it should or should not be treated as gospel, but here's what the manual says on the break-in period:

"Up to 1,250 miles/2,000 km:
Attempt to vary both engine and vehicle
speeds, but refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100 mph or 160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
Once you have driven 1,250 miles/2,000 km,
the engine and vehicle speeds can be gradually
increased."

Also, I have a question: I've heard some say that for Steptronic owners, it's best to drive in the Sport mode during the break-in period. Is this true?

The traditional idea is to avoid all those break in miles at the same level of RPM's. Just try to vary the RPM's while on the freeway. Drive in standard, sport, try out the step while commuting. This will help you vary the RPM's.

It's funny how break in is such an emotional topic, you should see how the Porsche guys argue over this... It's a religion to them.

The dry sump oil system only really comes into play under accelleration and long, sweeping turns where oil starvation might be an issue with wet sump systems.
