FINALLY! Tomorrow morning (monday), I will have my 1,200 mile service appointment to have all my fluids drained and replaced. Is there anything I should know besides not going above 137 MPH until 3100 miles (I don't intend on going that fast any time soon, unless I'm headed to Vegas). I've been a really good boy and haven't taken my car past 5,500 RPMs and not past 105 MPH. I maybe hit 6K RPMs by accident on 2 or 3 occasions, but that's it.

Can I just take my baby all the way up to 8,000 RPMs or should I gradually take it there in the next couple hundred miles or so??? I just want to make sure to do this right.

Let the "Sport" button pressing begin! impin:

dont floor it till 3100 miles:thumbup:

gradually increase the RPM's:thumbup:

flooring it is part of the breakin process. u can floor it, but dont let it rev above 6 or 6.5k for a while, then gradually increase the rpm's untill the 3100 mile mark. then u are in the clear for sure :thumbup:

 

[maynardc]

are you sure? on the break-in/warning sticker, it says that no full throttle (WOT) accelaration during the first 1200 miles. it says nothing about not flooring it after the 1200.

dont floor it till 3100 miles:thumbup:

gradually increase the RPM's:thumbup:

3100 miles is for the people that wanna go top speeds. You can floor it any time you want

 

[rumatt]

Anyone know if there is actually anything magical about the 1200th mile or if this is just a general range?

It's my understanding that the engine keeps track of the mileage and behaves differently as time goes by, so it's not impossible for there to suddenly be a big difference.

 

[maynardc]

makes sense. so between 1200 and 3100 miles it's okay to take it to 8,000 RPMs every once in a while? I guess this is my biggest concern, not necessarily the top speed.

thanks.

You can start going about to around 7k freely now but I'd wit til about 2k til you go to the big 8k rpm. I think your pretty fine to floor it now too.

 

[maynardc]

thanks for all of the great advice, everyone!

1200 miles is just a figure where they're 100% sure that any break-in processes have finished. From 1200, you should gradually increase your max RPM over the course of another 1200-2000 miles. "Flooring it" is putting the engine under heavy load, and as long as you don't exceed max RPM, you're fine (also make sure the car is fully warmed up first!).

That's what I figured. Just curious though... Do you know this for sure (from BMW engineers, etc) or are you just guessing?

wtf i only have 2355 and i floored it already...oh no
well its not a M car, maybe its alright......

 

[PhoenixM]

after 1200 floor that biatch!!!!!

It's a general rule of thumb that all automakers recommend. You can't "engineer' an engine to break in after x amount of miles. You just know that, with x material for the piston rings, y material for the gaskets, z material for the engine block, you can get an approximate figure for when everything should be seated by. 1200-1500 miles is the safest number to follow and should guarantee that everything about an engine is broken in. Sure, it's possible to poorly engineer something such that it takes longer to break in, but no automaker does that. Remember, they're just trying to cover their asses, and if it's about a longevity issue like engine life, then I'd take the safest word on the street (i.e. the longest break-in time) that has some validity to it. Granted, there's little I can do in an online forum to convince you that I'm an engineer, but I think it's common sense to play on the safe side with such high-cost items as automobiles.

Same goes for what happens after the break-in period. Sudden changes in stress are never good for components... things like sloppy shifting, flooring the engine, stalling, etc. all put more wear and tear on an engine than 'normal' driving would. Question is, do you want to risk putting those extra stresses on the engine when it's most susceptible to stress damage? Again, play it safe - follow the recommendations of the auto maker. In addition, who does it hurt if you do?

 

[rumatt]

Sure. I'm not suggestion that I won't follow the suggestions.

I was just wondering if the engine actually flips some kind of switch at 1200 miles. It may sound silly, but it's not impossible. I've read that the engine computer does behave differently after reaching certain mileages. I don't know this for a fact though.

Just wondered if anyone knew for sure.

Dude, just tear it up like you stole it. Its a perfomance car and thats what you bought it for. Its bad enough we have to wait till 1200 miles to do this.

honestly, i couldnt agree more........i know its rotten of me to say this, but are u that worried abt settling the valve springs correctly so they do not fail you 95k miles down the road?? prob not, u will not even have the car for 95k miles, and the next owner wont even question your break in process....and if he does, at lesat u brought it up to 1200 as recommended. Someone can feel free to put me in my place as i am hazy on break in procedure.
