Hey all,

I am picking up my G87 M2 early next week. I am a huge track junkie and will be putting all 1150 miles on the car in the first week as I have some track days at the end of the month.

Would BMW have any issue with such a quick break in service? Basically I'm asking if they have a time restriction to avoid people doing what I am doing...

I just had mine done today at 1,135 mi. I purchased on 11/28. I scheduled it using the dealership's online appointment scheduler, showed up two hours early (I was driving from 3.5 hours away), and they got me right in. Took 2 hours on the dot.

[M2siast]

Shouldn’t be an issue. Just make sure to book your service to make sure they fit you in.

My CA and SA both said there are no time constraints on the first 1200 miles. They did, however, recommend continually varying speed keeping RPM under specified value. Apparently a big no no is setting cruise control at one speed for extended periods. YMMV

Have not heard of any issues with a break in service done at any time as long as the miles are around 1200. Show up with some couple of hundred miles less you might get some push back.

Bought my M2 April 14. May 23 had it in for an early oil/filter service with just 647 miles. This was a service I was paying for out of my pocket. All that was required was I book the service. I don't recall how far in advance I had to book it -- the dealer was busy -- but I seem to recall it was at least a week or so.

Then May 31 had the car back in for its 1200 break in service. As before I had to book the service some time in advance.

Just bought a 2024 230i xDrive Dec. 1. And the other day booked it in for a check of the alignment, an early oil/filter service (will have around 600 miles on the odometer), for Dec. 13. Dec. 13 was the first time slot available. Dealer busy.

So book your service ASAP to be sure the dealer can do the service when you want and prior to your track day.

Why would you do this at only 647 miles... ?

Also note that the diff oil is in limited supply, so get your appointment booked early in order to give the dealer time to get the oil.

[DutchBoysRacing]

I already booked my service! Just need to car to get to me from the VPC and then time to grind those miles out!

[Geighty7]

I did all my miles within the first hour of ownership

Just like to change the engine oil early and even at 1200 miles I don't believe that's "early" enough.

When rebuilding engines the engine was started and run for 15 to 30 minutes at 2K RPMs or thereabouts. Rings seated in just a minute or so. The extra run time was mainly to ensure sufficient oiling of the cam/lifter hardware and let the cam/lifter interfaces complete their break in. Then the engine was shut off and the oil and filter changed.

So to run the engine even 600 miles is actually a bit unsettling to me.

Although old school engine break-in still applies to more conventional performance engines (20 mins ring and cam bedding at 2500RPM with break-in oil, followed by an oil change, then another oil change after varied revs but not redline for another 1000km with break-in oil is typical), modern engine materials don't seem to have the same level of break-in wear.

Our 2017 M240i B58 engine had no noticeable wear materials such as fine metal or sealant particles in the filter when it was cut open at it's first oil service at an early 8,000km / 6 months before the first 1-year dealer service at 15,000km. In Europe a large proportion of vehicles go 2 years from the factory on synthetic oil before the first oil change without any effect on engine life.

The key S58 ring and cam break-in will be accomplished during engine checks on the production line, the filter will capture any wear material that would be detrimental and looks as though it has the capacity (going by the same/similar filter on out B58) to capture any wear material over the first 15,000km of life without any issues.

S58s have been around for years now. I trust BMW knows what they're doing with recommended break in procedures otherwise they would be blowing up by now.

I see what you're saying & it's great to error on the cautious side. But you can also kills things with kindness too. BMW says 1,200 miles for RIS because that's what they deem to be the appropriate window. At 600 miles that's WAY too soon.

It’s 2 services in 1,200 miles, to be safer. It might be overkill, but it can’t do harm, it can probably only do good.
One of these is “free”. The other one is paid for out of pocket.

I get what you're saying man. But 600 miles is still a touch too early. Wish one of the S58 engineers could chime in on this & set the record straight.

What harm do you think it could do?

[Carefree]

I applaud Rockcrusher for caring enough about his car to do this. Overboard? Maybe. Unnecessary? Possibly. But in the grand scheme of things that $150 is a pittance for his peace of mind.

No harm. But don't components inside the engine need to properly seat & be bed in... ? Not allowing this necessary early on preliminary process to take place as recommended seems to maybe go against the grain. So 1,200 miles is twice as long as it needs to be & much too far out in some regards... ?

[kyrix1st]

I believe BMW still uses the conventional "break-in engine oil" with special additives for bedding in the piston rings. So I would stick with the 1200-mile break-in under normal circumstances.

As long as you drive the 1,200 miles you’ll break it in. The only way not to break it in is to not drive it. Unless I’m missing something, the break in still happens whether you keep the same oil or a new oil. The difference is that the new oil will have less metal shavings circulating back into the engine.
