Anyone planning on following break in procedure?
I'm not. I've been advised by many high performance and super car owners to avoid it if I want the best performance down the road. To their testament, I've driven all my vehicles hard from pick up and have not had any problems. In fact, I gave my supercharged range rover sport the hardest break in out of any vehicle and I'm putting down 0-60 times of 5.0-5.1 seconds consistently. Everyone else is doing about 5.5-5.6 seconds. I guess I'll be the guinea pig for the M5

I think someone on this forum received guidance from a BMW rep at the Welt that "sustained" speeds in excess of 100mph are not recommended.

But why would almost all manufactorers advise you to follow a break in procedure? I don't think they have it just to mess with people.. And I think it's mostly not for the engine itself, it's more for the wear and tear parts. But doesn't BMW (or is it Porsche?) have different oils in the car up until the first service? |

-Engine -Transmission -Differential They will usually change the oil and the fluid of these components during the Break-In Service. Some manufacturers use a special kind of oil or fluid for Break-In also. The reason for this is because when an engine, tranmission, or differential is brand new, all of the moving parts haven't gotten a chance to fit and form to each other over time. So there can be a little bit of rubbing and chaffing that goes on, producing tiny metal particles that would be present in the oil and fluids. This is why they change them during the Break-In Servicing. Additionally, now that cars are becoming more computerized, the software for the engine and other components may be programmed to keep the car from exceeding certain limits, such as rpms and/or speed. The best advice I ever got concerning the Break-In is to just not let the vehicle sustain long periods of constant rpms and speeds. The vehicle components need a high degree of variation in rpm in order to form the best bonds internally. Basically, don't drive for long periods of time on the highway with your cruise control set to 65mph. Work that engine, work those components, but try to stay within the limits as much as you can. I once had an E60 M5 that had an S85 engine shit itself on me. When I got my new engine in, my tech just told me what I just said in the previous paragraph. I ended up breaking in that engine by taking the car over 200mph during the RE-Break-In period for the new engine. After the Break-In Service the engine performed beautifully. As for the F10 M5 in particular, I don't know for fact, but based on those descriptions of those people in Europe and the rest of the world who have had the Break-In Service complete, I'm pretty sure that the BMW Dealership changes the engines ECU software whereby full horsepower and torque are now available. Don't quote me on that, but that's the impression I've gotten after reading so many experiences. As a side note, I plan on covering the required 1,200 miles during my Euro Delivery experience and I have already arranged for a BMW dealership in Germany to complete my Break-In Service, so that I may take my F10 M5 to the Nurburgring fully broken in. You only live once. Last edited by RPiM5; 08-10-2012 at 11:17 PM.. |

Couldn't agree with you more. There is definitely a wear-in period where materials forge to each other and form boundary layer lubrication. You want them to mate at various RPMs/speeds within the limit so as not to create resonance frequencies which may result in a more choppy transition. |

My shop just replaced an engine in an sti for a customer. My tech advises every one to adhere to breakin recommendations. This particular customer didn't. Ended up doing the rebuild a second time. The engine lasted 200 miles. Didn't even get a chance to switch out the break in oil. This is an extreme case, but I'm not going to take the chance. My old man bought a 2001 S430 back in the day from the dealer. In 2008 passed it on to my little brother. Car has +200k miles. Original everything. Followed break in. The race engines that someone mentioned earlier have up graded and forged internals that can take the heat. On a stock engine i wouldn't recommend anyone take the chance... Even if this is a super car ; ) after all, those German folks aren't that dumb. Lol

I followed the break-in procedures on my "first" BMW. I still have it! It's pushing 170K miles and it didn't require any major surgery.
For those taking ED - how much more is it to pay someone to do the 1200 mile breakin for you? |

The clutch that was installed new came out with multiple rashes or wear marks. The guy either missed the shift or just plain old tore it up. The tech has a track record with sti engine rebuilds.

As for the ED break-in, I plan to modulate speed and RPM all the way to the 'Ring (~350 mile), then I will consider her broken in. Realistically, in a new car on a strange and dangerous track, I'll be doing 7/10ths max and will try to short shift to avoid redline RPMs. |

from the 2013 M5 owners manual: Breaking-in period General information Moving parts need to be broken in to adjust to each other. The following instructions will help achieve a long vehicle life and good economy. During the break-in, do not use the Launch Con‐ trol, refer to page 73 . Engine and differential Always obey the official speed limit. Up to 1,200 miles/2,000 km Drive at varying engine and road speeds, but do not exceed 5,500 rpm and 106 mph/170 km/h. Avoid full-throttle operation and use of the transmission's kickdown mode for the initial miles. At 1,200 miles/2,000 km Have drive-in checkup maintenance performed. From 1,200 miles/2,000 km to 3,100 miles/5,000 km The engine and road speed can gradually be in‐ creased to a constant speed of 137 mph/220 km/h. Use the maximum speed of 155 mph/250 km/h only briefly, e.g. when passing. Tires Due to technical factors associated with their manufacture, tires do not achieve their full trac‐ tion potential until after an initial breaking-in pe‐ riod. Drive conservatively for the first 200 miles/300 km. Brake system Brakes require an initial break-in period of ap‐ prox. 300 miles/500 km to achieve optimized contact and wear patterns between brake pads and discs. Drive moderately during this break-in period. Clutch The function of the clutch reaches its optimal level only after a distance driven of approx. 300 miles/500 km. During this break-in period, engage the clutch gently. Following part replacement The same breaking in procedures should be ob‐ served if any of the components mentioned above have to be renewed in the course of the vehicle's operating life. |
