Is there still a run in period for new cars? What were you guys advised to do when taking delivery of your new JCW's?
Run in period
1 - 20 of 40 Posts
I think there is a lesser need to be very cautious with modern vehicles. Personally i would not drive it like you stole it but just have a little bit of fun now and then until the 1200 miles is up.
Just follow the basic rules, warm the car up before you rev it hard, perform maintenance regularly and enjoy.

I'd say don't bother... I let my SD slowly come to life with the first tank of fuel. However when my mum picked her JCW up, we got out to the smell of hot metal and plastic... You only live once.

I'm planning on doing the odd weekend oil change myself on the JCW as I used to with all my previous cars, I'm planning on giving it an oil change after the first few thousand kms as this period is when the engine sheds the most metal, I'd like to do the same with the auto transmission but sure this would be a lot more difficult, not sure how these are made or put together. Or if you can even change the auto trans oil.
i did my break in period on my jcw 16' 1200 miles/2000km as much as i wanted to push the car its a 50/50 thing some agree some disagree with it but the owner manual said it so im gonna do it (guy at the dealer told me 500km is fine but eh bmw know more about their car so i follow the manual tbh) glad i did and i changed my oil at 1800km there was a lot of little shiny metal piece in the oil
oh and for the auto transmission fluid i wouldn't touch that tbh just my 2 cents

Run-in isn't only about the engine, but all components on the car...engine, transmission, clutch, differential, brakes, suspension, etc. I've noticed a drop in the stock suspension on my JCW over time too! It takes time for moving parts to mate with surfaces where parts are moving! I believe a proper run in is just being sensible, but not driving like an old lady either! lol! Keeping the rpms under 4500 is too challenging for most of us & I don't think it matters at all....it's more important to not over-rev and just be responsible...but that should always apply anyway right? Just don't autocross or race the car when brand new! ;-)

Does anyone ever read the manual? It states very clearly not to exceed a certain amount of revs or labour the car.similarly not to use brakes harshly initially though that's not easy in an emergency! There is a lot of opinion on the matter and its really interesting but these days cars are well made but the mini engine is not run till the car is complete and it is driven out the factory on to the transporter. Do the factory tour.(fab) Best run in cars according to honest john are those that experience a very varied regime but neither thrashed or laboured. Oil needn't be change as there aren't lumps of metal wearing off any more but if you want to it wont harm!

Exactly:
Breaking-in period General information
Moving parts need time to adjust to one an‐ other (break-in time).
The following instructions will help accomplish a long vehicle life and good efficiency.
During break-in, do not use the Launch Control, refer to page 61.
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road speed:
▷ For gasoline engine 4,500 rpm and 100 mph/160 km/h.
Avoid full load or kickdown under all circum‐ stances.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be increased.
Things to remember when driving

Tires
Tire traction is not optimal due to manufactur‐ ing circumstances when tires are brand-new; they achieve their full traction potential after a break-in time.
Drive conservatively for the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐ prox. 300 miles/500 km to achieve optimal per‐ formance between brake discs and brake pads. Drive moderately during this break-in period.
Clutch
The function of the clutch reaches its optimal level only after a distance driven of approx. 300 miles/500 km. During this break-in period, engage the clutch gently.
Following part replacement
The same break-in procedures should be ob‐ served if any of the components above-men‐ tioned have to be renewed in the course of the vehicle's operating life.

If this is what BMW/MINI really mean then they should get their own house in order first because every dealership I've had dealings with their staff all drive like they stole it including customer cars..

Personally I believe there is no reason the run in, I don't mean red line it everywhere but drive it how it is meant to be driven ..

I know exactly what you mean Daveyboy. Dealers seem to use it as a silly boast
h our cars are so well made they don't need running in. However the manual does say below 4500 rpm initially .mind you since this equates to well over 80 mph in sixth its hardly running in as cars used to need.and no running in oil and hence change as we used to have to do.
I remember when synthetic oils first appeard they were not allowed be used an engine till it was run in!

That is why im very hesitant in buying dealer demo cars, they are usually driven very hard for short distances and not warmed up properly. If carsare going to fail, these would be the first.

It's a demo and regardless how she may drive it they have punters who take it out and I bet a high percentage give it stick..

That's true hadn't thought of that one. As you say they lose their cars to demo plus service loaners. Mmmm
