1200 Mile Break-In Period
Not sure if this has been covered before, but is there a particular reason BMW set 1200 miles as the break-in period mileage?
Because my car is purely a weekend car and I'm typically busy as hell with work, I'm struggling to get to 1200 before winter hits here in the NE and I have to prep the car for winter storage. First world problems I know. Last edited by MMMBRAP; 10-14-2019 at 01:44 PM.. |

There is a ton of information online, but my understanding is that the 1200 miles is so there is enough wear on the diff and engine so that all the small metal particles generated from the break-in period are removed with the initial diff and engine oil changes.
Personally, I'd wait until at least 1000 miles.

Zeee Germans are just rounding off kilometers to miles. 2,000 kilometers = 1,243 miles.
I know that's not what you were asking, but I had to. In all seriousness the engine for the most part is broken in from factory, but there can still be some further bits of metal that need to be worked out. Better safe than sorry. The major part of the car that needs to be broken in is the entire drivetrain. IMO follow the break-in procedure and be patient. You can still get your oil change at 1yr or 10k miles, which ever comes first. |

Yes, agree with what KevinM said. BWM say the oil needs to be changed something like every 10K or once a year so the break-in service 'short cycle' is to get the initial fill oil out of the engine and diff which gets contaminated with tiny metal particles which have come off the gears and other rotating parts. You would hope the 1200 number comes from testing where BMW determined that was the optimum point to remove the initial fill oils.

My dealer said they will do break in service on M cars as early as 700 or 800 miles. I’m sure some may argue the validity of that but they have a race team so they probably have some sort of reasoning behind it.

For the engine components I would think the oil filter. For the diff there wouldn't be any; the particles would be in the diff fluid, which is completely drained and replaced.

I'm such a creampuff I was traveling, I had chemo treatments and some work but NOW I'm cancer free, no more work this year and I'm getting a winter wheel set up from sun motors PA drive late late @ night or early in the morning to get some clear roads to break er in drop off car for for service on a Saturday so you will get a loaner for minimum of 2 days that way you can have a clean loaner to pickup whores in that have glitter and cheap perfume, smoke cigars with friends (no evidence of your weekend) in a loaner Public announcement: Herb Chambers BMW loaner x3 Sapphire Black with sticky back seats is a sav you want to AVOID 😐 Edit: off topic, strange year high highs and low lows, i took the year off work (self employed) I got to travel with my son for the euro delivery, wife to Greece and nephews and son to Yellowstone, getting healthy changed my perspective on life, not wasting energy on anger or regret, living each day as a gift, rainy Wednesday night in boston my wife made spaghetti and meatballs (normal simple home meal) I kissed her telling her I'm happy we're all here eating this plate of heartburn togeather |

Before they started paying for "scheduled" maintenance, all new BMWs required a 1200-mile break in service (oil, diff and tranny fluid).
Curiously, my dealer told me they won't CPO an M model unless it had the break-in service before 1500 miles. I've never heard of that, not sure I believe it, or perhaps it was specific to this dealer. |

Yes there are reasons, just drive your car to work a few times and you'll hit your mileage. |

For me, I took a day trip up into the mountains, twice. It made for nice changes on the engine and transmission loads. 2 lane, of course, except for a short stretch of highway to get some speed miles in. Since that day was only about 300 miles, I did the same thing the next weekend, to a different pass. I put on my 1200 in about 3 weeks, and got some nice driving in as well. Now, almost 2 months later sitting a little over 1500 from the daily commute. I need another mountain trip before the snow hits.

if you're really curious how your S55 has done during the break-in period. Get a Blackstone Laboratories oil analysis done. Contact them first for their mail-in sample container. Fill it as directed and mail back for your oil analysis. Money well spent.

You can always pop it on blocks and Ferris Bueller the car.
On second thought, that didn't end well... |
