Hi,

As I am new in diesel engines (I am waiting my V40 with a D3), I would like to ask a couple of things.

Is there a suggested/required break-in period? Also, I read somewhere that irrespective of manufacturer requirements, it is generally a good idea to change the oil after the first 4-5 thousand kilometers in order to remove any artifacts coming from the engine production/machining etc (burrs are they called?).

What does the wise V40 forum have to say on these newbie questions? :blush:

I bet you'll get mixed reponses from this question! Probably based on the age of the driver..

Here's my 2 cents:

In terms of economy a good few thousand miles untill its loosend
In terms of driving, don't need to break them in as there ran and tested in the factory so you don't have to be gentle

Changing oil? If it was that important/urgent volvo would surely reccommend it..

I can second this comment...
Break in is something that used to be applicable in the last..
Ofcourse don't go revving the engine like crazy

There are dealers that have cars come in after the first 10k km's.. But mine just says after the first maintenance period (1 year or 30k km)

I thought about this as well, so I read some recommendations online, most of them mentioned that being just a little gentle won't hurt.

My friend, who's in the business, told me I should drive her normally, try to avoid full throttle accelerations for some time, but do not drive too careful, I should just drive normally.

From what I read online, keeping constant speed at the motorway for a longer period of time, when she is straight from factory, might not be the best idea. Though, as already mentioned, the cars come already broken in, so we do not have to be excessively careful these days, I suppose.

So for now, I just drive the V40 normally, without making all too many fast accelerations though, to be on the safe side.
