Run in period

[mkot9]

Who sticks to the run in period when purchasing a new car and how important is this?

I did. Didn't take very long to cover the 2000km and it kinda got me used to the car before I started nailing it. Tbh, it had more than enough grunt up to 4000rpm so it didn't really matter all that much.

I wait for car to be warm enough, and off we go!!!:rollsmile:

Never waited for 1000km or 2000km, but I didn't nail it all the time either, only now and then.

Flip my last Hilux I bought in 2011 was an Auto, I was used to a manual with a chip, with 250km it was chipped already as the Auto was sluggish. It's never had an issue!!

Perfect, because I've been going crazy with my new car and the launch control is amazing! Only time it gets driven slowly is in eco pro mode

 

[Magneto]

If it caused damage to the car BMW would ensure Motorplan doesn't cover it. Give it horns I say, and enjoy!

I dont think it would cause any danage, because when the car does its testing it surely doesn't get run in first? And can BMW pick up if I was driving the car to hard?

If I buy a new car again, yes I would. But this is a somewhat controversialist topic - some believe in driving hard from the get go, and some believe in running-in a car.

I think it makes sense to allow the engine and all other mechanical items to gently wear in, and as always, it is crucial that it is driven gently while cold and warming up - driving a car hard when it is cold is never a good thing to do!

When running-in, it is important that you never stick to constant speeds, best is to continuously adjust your speed. I also believe in having the engine oil changed within the first 1000 km or so.

Thanks for the advice Philip, normaly start the car in the morning to get the warm up started and drive slow for the first 10 minutes. After that I hammer it to like 120km/h, but after that I drive slow.

 

[Philip Foglar]

Best to start the engine and drive off immediately - idling a cold engine is not good! Most engine wear takes place when the engine is cold, and with the engine idling while cold, there is more fuel in the air/fuel mixture which tends to wash away some of the oil in the cylinders. So the safest is to start the engine and within a few seconds all fluids have started to move around and pressure is built up, drive off gently and you are good. What does help is that most of the newer BMW engines have clever heat exchangers which are able to warm the engine up quite quickly, but you also have to consider the gearbox and the rest of the car's mechanical parts that also have a certain optimum operating temperature.

Perfect, thanks Philip

Of course u should run it in. Run it in Hard. I dont wait to give it horns. Never had any issues.

My brother used to work for BMW in the UK. A while back he told me a story that has a bit of relevance here I think... They had a brand new E46 318 individual on the lot to be used as a demo. Problem is nobody wanted to drive it because 318. For the duration of the run up period he drove it HARD up to 4000rpm before changing... Obviously let the car warm up before hand and so forth. He said that that car turned out to be one of the nicest, perkiest 318s he's ever driven... So yeah I think there is merit to a run in period

 

[mkot9]

I have found the same in my megane RS. From day one I drove thi s#%*t out of it and on thr Dyno it made 181kw on the weels and the car stock had like 184kw, but!!! I had to replace the brakes 3 times in 12 000km and screwed up the gearbox aswell

 

[Quick///M]

The run in as per manual is 2000km, you can't drive slow you have to drive passed 4000RPM up to 5000 RPM every time you are on the road just until you hit the 2000km mark the reason for this is working the internals in.

Driving the m235i very slow would actually cause more damage. This info was from a bmw tech can't remember which forum it was

 

[mkot9]

:biglol: I like it!!! Will do a video this week on the launch control

 

[Rayzor]

I just follow instructions from BMW and "drive it like its stolen" :biglol::roflol:

I have researched this in some depth..

The best way for engine longevity is to observe the run in period.

You negatively affect the engine longevity to a large extent when it is not observed. An engines peak performance is actually around the 20 000km mark, if run in correctly.

Motors are bench run, but only to check for any errors, they are not bench run for any amount of time that will be considered sufficient to run in a motor.

If more detail needed I can help..

Sweet..

I normally trade my cars in before motor plan is out so i run my cars hard straight out the showroom,

My 330i had 246k km(my love so i kept her the longest) on it and driven hard everyday and not a day problem, i suppose you get a bad car once in a while and no matter what you do it goes bad so i dont care much for driven "slow" or run in period

 

[Gizmo]

Get the oil up to temperature and then give it horns! Thats what motorplans are for...:fencelook:

 

[mkot9]

The only problem I have experienced when doing this , is I think my petrol tank is leaking. I'm only getting around 180km on a tank and its a bit expensive! :roflol:
