Stick with shell;) and do some good mileage before start adding anything to fuel and only when it is necessery eg drop in fuel economy..

+1, mixing additives isn't recommended - you never know what frankenstein fuel you are creating!!

2200rpm is my usual change up and 1500 drop down. Well my ruetine has been 2 top ups with nitro v+ then 3 with tesco and 100ml of natural 2 stroke. I seem to not have had problems when running and I believe this does the same job as injector cleaners of lubricating and cleaninv the injectors and fuel?

Good info

Some related info and advice.

I did this when I received my new Civic 2.2 diesel 7 years ago. And again 2 years ago when I received my Alfa 1.6 diesel.

Result, oil consumption is zero.
Fuel consumption is good, unless I go over 130 Km/H, but that's my own choice.
And on the Autobahn I can reach the advertised topspeed. Perhaps even a little bit more if I would keep on flooring it.

Sounds like a proper run in engine to me.

Very interesting info and thanks for sharing! I 'd be most happy if I manage to have the same experience in terms of oil and fuel consumption. I 've got two remarks.

I see that you recommend using the whole rev range from the very beginning. That contradicts the opinion of gradually increasing the use of revs with mileage (which I personally opted for).

Why do you strongly suggest avoiding motorways? In order to be able to vary the revs?
I have used them (inevitably...) and I always tried to vary the speed (e.g. 90-130 km/h) and to change many gears, also by doing (carefully of course) the lift off that you mentioned (but always in the range 1.5k-3k). Furthermore I think it is useful for the whole car running-in (not just the engine)to include some driving in these speeds.

Has anyone thought about guys driving cars out of factory and in ports? Dont spend to much time thinking about running in.. drive it normally from start..

The car is in limp mode. Won't go past 3 000 RPM and the TCT refuses to go past second gear. My first test drive was in a Giulietta that behaved like this. Kind of a disapointment until I realised what was the cause. :)

To be fair, it's not my advice, but something that I came across on that site. Also, I'm not an engineer, this just sounds reasonable to me with my rudimentary engine knowledge.

I don't think they recommend the whole rev range from the start, but do this AND keep on gradually increasing the max revs. They mention high-ish, what that exactly is is debatable. I guess it means you should not be afraid to give the engine some load. You need to be little careful at first, but don't be too careful. Reaching 3500 revs for a bit on the first run (when it's warm!) should be OK, according to that advice. Just don't keep it there.

About the motorways, a little bit won't hurt. But doing 200 km from the start at more or less regular speeds doesn't vary the load and stress the engine enough. You need that pressure to build up, so driving in the countryside would give you the perfect opportunity to give very speeds, gears, acceleration, let it coast and cool for a bit.

What's in these additives, anyway ?
Solvents , detergent ?
Not good early on in a cars life , perhaps?

The problem is that its a bit like mixing your drinks, mix the wrong ones and you can end up with a poison.

Isn't the Ecu programmed to allow more power after a certain mileage? Mine certainly feels that way.

Mine was delivered in D mode.
Also I was told that the engine opens up at around 2000km (1250 miles), which I have seen (at around 2200km car became more responsive and fuel consumtion dropped for approx. 1L/100km).
But I do not know what is the case with diesels.

To be fair mine feels like it opened up more than when I got it 10k miles ago at 7k miles, it certainly feels like its settled now. So I think with diesels or at least the 1.6 its improving all the time till somewhere between 10-20k
