you press the throttle all the way... and the a little bit more and you will feel a click...when the kickdown is activated the car will multi-gear downshift to the lowest allowable gear

I was told about this break in period by the BMW employee who delivered the car to me at BMW Welt. I strictly adhered to it for all 1,200 miles. Nothing over 100 mph, and never flooring it. Staying out of Sport mode kept the RPMs where they needed to be, except maybe once or twice.

I'm at 2100km (4 weeks since delivery) and drove it in comfort and sport mode thruout.. never thought about the break in parameters yet I didn't have a situation where I needed to rev higher than 4500 nor break 160km... yet
I find the Michelin PSS tires need warming up tho in the morning commute... |

Correctamundo, on the autobahn. Did it myself some years ago. I was thinking here in the States where, for the most part, there aren't a lot of 140+ opportunities on the highway and, even if there are, you stand liable for felony speeding which could include confiscation of your vehicle. Don't get me wrong, I like to go fast and actually have a great road (Hwy 70 from Las Cruces thru White Sands to Alamogordo) to do it fairly sanely and safely. Just need to do it away from people...

Never done break-in period, 23 cars and counting never had an issue.
But in all fairness I've never had a car over 30,000 miles. I kept, and do. keep in touch with many people I've sold my cars to, never heard an issue ever, but didn't ask about it specifically. Including 98M3, 02M3SMG & 08M3. |

To properly break-in (or as some spell: brake-in) an engine, you must bring up the RPMs to the point at which you intend to drive it at. If you baby it and keep it under 4000 or 4500, the rings will seat in to that point and could have issues creating cylinder ridges at the point of TDC (top dead center).
Higher RPMs stretch out the metal parts. The pistons go farther up the cylinders and the rings then go farther too; seating the rings to the full and expected range of movement. Racing engines must be broken in to the RPM at which they will run or they will not perform properly. The best way to break in an engine is to slowly bring up the RPM and do not (I repeat DO NOT) stay at one RPM for extended periods of time within the first 500 miles. Do not lug it or ride at 55 or 65 mph constantly in the highest gears at 1.5K RPMs on your commute. That is the worst thing to do. Best to vary your speeds, but more correctly your RPMs. It you must commute the car in the first 500 miles, use a variation of lower gears to get the RPMs up. I use this procedure during the first 300 miles or so. Use the manual shift in the automatic transmissions to vary the RPM from 3K to 3.5K for a few minutes each and slowly bring it up to 4K (hold for a minute or two), then 4.5K, then to 5K for the same delay and then back down to 4.5K, then 4K, etc. Use a variation of RPMs between those listed. Repeat this several times. Do this on the Freeway when there is no traffic. There is no need to speed and load does not matter. Go to higher RPMs if you plan on running your vehicle at 6K, etc. For most, 5k to 5.5k is sufficient for quick accelerations. Racers will want to progress higher. The worst thing is to jump on the engine and rev it high and back down again quickly. Ease it up there during the first 500 miles. All of this is at your risk and is my opinion from experience with racing engines. It is your investment. P.S. I think the initial autobahn runs mentioned are very beneficial to new engine break-in. |

When I picked up my 128i in Germany I followed BMW break-in procedures fairly strict. I also got to drive my car for an extended period of time ranging speeds from 10mph to 100mph and engine rpms 1,500-4,000 for the first couple hundred miles. Got 93k miles on the engine now and I have never added a drop of oil between changes with the longest change interval at 18,000 miles. I know I know I am a terrible car person but I did send Blackstone Labs an oil sample and they said the oil was still good to run on. However I think the overly used oil was starting to cause the electronic dipstick to give bad readings. Lastly to this day my engine feels and sounds like the day I got it from the factory.
I think a good engine break-in will go a long way. |
