Good video, should have gone into the programming process to remove run in service.

[MrOhnoez]

I know before the break in on my M2C, it was so difficult to shift smoothly perhaps attributed to the diff fluid, it literally looked like sandy oil coming out. Once it was done, it shifted like butter.

I was waiting for the million dollar confirmation that the break in maintenance does not open up performance rather than simply allow the car to perform at it's designed performance.

Even when not recommended yes I did a break-in

I couldn't get an appointment for 3 weeks at my dealer (booked solid when I took delivery), hit 1200 miles and they said it doesn't matter let her rip. Didn't go bananas until I had the service at 1800 miles, but highly doubt this matters. It's really about letting all the parts congeal and break in together. I will never understand people who don't follow the break-in procedures…

Well, that’s pretty much the “tide pod challenge” crew.
If they can get anyone gullible to follow their horrible advice they laugh, dance and drink to the devastation.

You gotta know who you are watching.
Amazes me how many people are unfamiliar with the concept of schadenfreude.

It's crazy to think these people believe BMW would pay for all these free break-in services around the world if they were unimportant.

[DarkNight707]

Great info… Thanks for sharing!

[Djhawkg79]

Yes. Only 'full' M require the 1200 run in service. Not sure of M50i. The owners manual will tell you.



2022 M50i owner here..... vehicle DID NOT request a oil change until somewhere around 9000 miles.

there are idiots who also believe the earth is flat. there's just nothing you can do to educate ignorant people

This is hogwash. Many vehicles come from the factory with full synthetic oil. Corvettes, M-B, CVO Harley-Davidsons and others. They will just take a little bit longer to break in.

Hearing the same. I assume there isn't an aftermarket diff fluid that they will substitute?

If you ran fully synthetic from the get go you'd end up with an engine that won't bed in properly resulting in poor piston ring sealing and increased blow by resulting in oil burn and power losses.

There is no normal oil made that is so slick it stops modern ring sealing. The break-in oils in the past, and still today for engine builders of flat tappet V8s, is actually extra additives to stop cam lobe and tappet scuffing. In years past piston to wall clearances were tighter but vast improvements in piston technology and manufacturing have eliminated the need for tight initial fit and the risks of piton skirt scuff and failure. There were loads of reasons 50 years ago for break-in oil and brea-in drains of fluids. One of the biggies is that the engine did not have a determined vehicle when it was filled with oil in times past and break-in service was the chance to get the right viscosity in it for the climate (and years before, for the season when oils ere different for cold and warm ambient temps). The S motors have tight running clearances for crankshaft mains and rod bearings and BMW likely does use an enhanced additive package and an altered viscosity in these engines for initial starting and the multiple starts before it gets to dealer. It is never bad idea to do early drains, even if the ONLY thing it fixes is your peace of mind, as any metal or other debris can get out sooner. Magnets in drain plugs or transmission pans can be cleaned if accessed and that is also never a bad idea so that magnet can hold more as they lose hold power when there is accumulation. I worked for a car manufacturer (and before that, dealers) and did a few port visits where vehicles came off the ships. Your vehicle has been substantially broken in before it ever gets to a dealer. Most vehicles gets loaded and unloaded between many transporters before it gets to you. End of line to factory parking, parking to truck if the train line isn't on-site (not sure about which BMW plants have resident rail lines), truck to overseas shipping, offload from ship to port parking, port parking to port inspection and processing, processing back to outbound lot, lot to truck or train depending on the port and final destination, if by train then there is train offload to lot and then loading for truck and then finally it is at dealer. Not all those different handlers will be kind to the vehicles. The period between starts will be hours to weeks. The guys that off load ships often run into boat from lot shuttle tram and race to see who gets down ramp first. You most certainly do not get to pop the cherry on that ride when it gets to you, you are getting sloppy seconds.

Has been common knowledge for years now since they implemented it, not sure what the shock is. It's why you always make sure the break-in service was done on a used vehicle

BMW used to require 1200-mile break-in service for ALL cars, I definitely had it done for my 1996 E36/5 per the manual (oil and diff change). But once they began paying for scheduled maintenance, the 1200-mile break-in service was done away with except for M cars.

(Coincidentally around the same time the OCI increased to 15K and diff and manual tranny fluids magically became "lifetime fill" on non-M cars).

free ? Ain't nothing free. You've already paid for it with the car.

Which is why I cringe to think about buying a used M car. I knew who the owner was of my first M car and my current F90 was bought new…gonna hang on to it for a while and keep doing full maintenance per BMW. 4yrs and counting…

[TractionControlDelete]

Motorrad division does the same thing for the bikes.

Great video, really enjoyed it and I think it's something new M owners should watch before they make a mistake with their new cars..

[Efthreeoh]

M is for Marketing. The more you can change oils the more special your M car is.
