Breaking in a new car?

Is breaking in a new car still a thing or does bmw break in the cars during production? What's the proper method to breaking in your car? I currently have 230 miles on my m340 and I've been driving aggressive at high rpm's without remorse. After all, it's a lease and fully covered under warranty so why bother babying it during the first 1000 miles?

What's the point of asking now after you have admitted to driving it hard already? what does your manual say?

Ps. Most here will tell you it makes no difference. Regardless I followed the manual and mine still required a quart of oil just past 3k miles so I guess let her rip. Keeping RPM's down for the first 2k miles had no added benefit in my case.

Nope, run-in period is for the owner- there are clear instructions in the app regarding this

BMW recommends waiting until 1,200 miles before driving aggressively. I think the recommendation is to not exceed 4,500 rpms or drive above a certain speed during that break-in period. Whether it makes a difference or not long term is up for debate.

I'm also leasing, however I adhered to the break-in period because:

1) I respect my car - to me it's more than just a machine, and I treat it as such with care.
2) At some point once I've turned in my lease, it will hit the used car market, and another owner will take possession of it. If I've treated my car like shit while it was in my possession, all I can say is, karma's a bitch.

I'm past the break-in period at this point, and I do drive it aggressively sometimes "the way it's meant to be driven", but I'm not needlessly reckless with it.

You're going to be just fine and the car is going to be just fine. I wouldn't worry about it. You paid for it. It's your car and you can drive it how you want. Revving the engine aggressively is not going to void your warranty. I've never broken in my vehicle and haven't had any major issues for the past 3 leases. My brother babies his cars and he's had numerous mechanical issues-go figure.

I have had to put new tires on before i turned in my lease so keep that in mind- and also now-brakes are no longer covered.

Just one tip-brand new tires don't have have full grip yet so don't take corners too hard for the first few hundred miles.

I'm sure the lovely people at VPC are extremely gentle with our vehicles.

One reason I like ordering cars that aren't already in inventory -- during test drives, cars get pushed hard (and the salesmen encourage it). I think hard driving in the first month or so isn't the best plan for longevity for the vehicle, but then I buy instead of lease and tend to keep vehicles 5-7 years. Folks who lease probably don't care as much about this.

When I hear people say BMW reliability isn't what it could be, I think it has far less to do with the actual quality of the vehicles than it does the typical driving habits of BMW owners versus other brands. Buyers who are interested in a performance brand are going to push their vehicles more than average. I'd be willing to bet a granny-driven BMW will outlast a granny-driven Ford any day.

Good video on break-in.

The modern car engines are designed to gradually run in, reaching optimal performance/efficiency at around 25,000 miles. Most engine experts say drive it moderately (not babying it, but not WOT either) and varying RPM/load for about 500 miles. I don't know if "rushing" the run in by driving aggressively right away would affect the longevity but I do think it's better than babying it the whole time. Most owners don't keep these cars past 25,000 miles so this may be a moot point.

BMW shouldn't lease cars to the immature. It is lease, so if you can't afford to buy it new, then do you think it's ok to beat on a car you don't even own...

Iím assuming then that you buy cars on straight cash? Bc you technically donít own it until itís paid up with financing either.

Yes, the only way to buy. And banks just want their money. Lease, BMW wants their car back in reasonable condition. But that's not always the case as some kids have no respect for it just because they can afford a lease payment.

Wow, I'm reading some of these comments and just wow. One guy says "respects the machine" and "karma is a bitch" another guy judes an induvidual for "leasing his car and driving it hard" and being "immature". It's comical really. For one, it's a production car, there are thousands of the same model car rolling off the assembly line, and the b58 engine and other components are throughly tested before it rolls off the line. I understand a break in period for an engine you've built yourself, because of metal shavings that are being created and to make sure that everything operates as it is supposed to. But regardless if you leased, or bought it out right, you are paying $$$ for it. Money that you spent earning. Its meant to be driven to your liking and if you wanna WOT it all the time, go on ahead. Respecting the machine and caring about "karma" is the most rediclous thing I've ever heard. You'd be surprised how many of the cpo M division cars were tracked. And if you bought one used, yours was probably doing laps before "break in" period was over😂.

Nowhere in my post did I state how I feel others should drive their vehicles. I simply stated what's in the manual, and my personal reasons for adhering to what's in the manual.

I'm also not against tracking a car, but I personally would buy the car rather than leasing it if my intention was to track it. And I sure as hell wouldn't track it within the break-in period.

The other point I will make is this - many people use the fact that they're leasing to mean they can openly abuse their cars because at the end of the day, it's not their car, it's owned by BMWFS. This doesn't sit well with me morally, and you may find that "comical" or "ridiculous", but I'm not telling you how you should treat your car, nor am I judging.
