fannying around at low revs and minimum load does nothing but build up carbon which transfers to the exhaust or the oil (depending on it's location) the key to reducing wear is to get the engine up to normal operating temperature before applying (significant) load and to allow it to cool down (up to two minutes) before switching off
I totally agree with this......especially the cooling off bit....once its up to temperature it should be worked hard...the higher exhaust temperatures power the turbocharger up to its full speed which makes the turbo compressor feed in the right volume of air, diesel engines have to breathe to work efficiently, Low revs or no load high revs on a turbo-diesel isnt a good idea.
The other threads mention of modern oils.....I still would & do change oil mid service....the oil is OK but by changing the oil all the crap (carbon, water, metal fragments are removed) this can only be beneficial to a long term prospect engine. BREXIT - done properly.

So, why does the manufacturer not tell you to bury the throttle and go for it then  ??

Interesting debate this...
I spoke to a Mechanical Engineer specialising in Diesel and Turbo Diesel engines. His theory is in line with that of 10FC and BLFarrar.. thus start driving the vehicle as you would normally do.
He made 2 points that was touched on by both
1) Diesel engines with Turbo’s need to get to temperature then run at “normal†operating conditions. Thus making sure the Turbo spin at speed to ensure you do not build up unnecessary EGT. Also he said although many with modern engine technology do not put high emphasis on this anymore, he still believes in running the engine for 30sec after an urban cycle and 2-3 mins after a motorway cycle, thus ensuring you get oil through without “glazing†on the hot metal.
2) He also suggested that you DO make use of mid service oil changes. He actually believes even with modern oils and engines you still need an oil and filter change every 10,000Km. This is especially true in Africa where Diesel can be of poorer quality.
As said... interesting debate..

Yep, intermediate oil changes are a big factor in engine life, probably more important than driving like  for the first 500 miles or so - in terms of engines, this is really neither here nor there but will have a greater bearing upon the driveline and braking components.... which is why vehicle manufacturers recommend it!

in older times running in an engine was the done thing
now just drive it normally and will run itself in
i have disc03 tdv6 auto with 60000km on it and it is going like a dream
i did not do anything special when i got it fiest

Only comment I can add is for the first 15K check the oil at least twice a week / every fill up - they seem to drink it at first then ease of consumption rapidly
My Brother in Law has just got an ex-dem and I advised my sister to make sure he checks it as he apparently has not opened bonnet yet
I would think that once the warning light comes on at speed, the engine is probably s  gged

Doesn't the D3 have a level (not pressure) sensor in it for oil level ?

Not that I am aware of - just a very difficult to read dip stick
I used to have a Merc that I could check the level from the info display - it did not even have a dipstick that I could see unless it was hidden under the plastic covers

the length of journiey..lots of stop start journeys if possible should be avoided......I once collected a Volvo car in London (Tax Free) & in the first few hours of use drove to Yorkshire then on to Carlisle, next day of to Donegal. This engine was superb whilst I had the car.
On the drive north I used the A1 - mixed speed driving up to 60 mph with no slow speed driving in higher gears.
My Disco3 has only "come good" at 13 k miles when I did a Yorkshire - London - Belfast - Yorkshire towing large car transporter trailer. Its a different car after this trip, better fuel consumption, performance, quieter, smoother. BREXIT - done properly.

I am with TFC and BLF, I have 4 transits and 3 sprinters, in the last 3 years I have bought a new van every year and promptly driven them to the Czech Republic as I am building a house over there. After the 2500 mile round trip they have then had an oil and filters change, after 24 and 12 months respectively they both use virtually no oil and are more economical than the ones that haven't been introduced to the Autobahn!
Personally speaking the best vehicles I have had are ones that have been worked hard (given death) from day one. I remember picking up a 300 tdi Disco brand new from the stealers, un-hitching the digger and trailer from the back of my 90 and hitching it straight onto the Disco - which had been running for 15 minutes.
The stealer got all y saying I would void the warranty  . I pointed out that if he could show me where in the manual it said that, I would unhitch it and call for another LR to take it back to the yard.
He then gave up arguing and sent me on my way, that Disco is now on its 3rd owner, all mates and it is still going strong, using no oil at 170k.

When I purchased my 07, the dealer told me that I don't have to run the engine. Just drive it 'normally'
I must say that I took it gently over the first 500 miles, (i.e. no high revs - stay below 3000rpm) and no quicks-in.
now, my driving style is pretty much the same but more for economy reasons than anything else. I achieve around 30 mpg, whilst a mate of mine of drives like mad get 24 mpg!
I think that modern engines are so good that an oil change at every 10,000 miles should be good enough to ensure they last for years and years to come... nothing yet.

the thread started with if, how or for how long an engine had to be "run in" for.....well described & documented in the posts...then oil change frequencies got into the discussion.
Oil Changes....yes, modern synthetic & semi synthetic oils do "last" far longer than the oils economically available some 10 years ago - when 'normal" service oil change intervals were 6,000 miles/10,000 ks. Times have changed....mostly for marketing purposes service intervals for turbo diesels have gone from 6,000 miles & an oil change at every 3,000miles to 10,000 miles 14,000 for Land Rovers (18,000 for Audi VW & others).
The centrifugal oil filter on the Disco 3 that allowed longer oil change intervals isnt on the Disco3 - yet the oil change intervals are longer - the properties of oils didn't do a step change & the metallurgy properties of engine parts didn't alter either.
Its your choice how often you change the oil - ask dealers & service providers what other customers do - lots change oils at more frequent intervals. If you intend to keep you Disco for beyond the warranty period & a long term (keep it for ever) basis oil changes at more frequent intervals will prevent the costly disasters & short lived engine life.
Changing oil is low cost maintenance (& good engineering practice).....frequent oil changes at sensible intervals saves cash in the long run. I also believe that oil ought to be changed say 1500 to 2000 miles into a new engine...the debris that comes from any new engine in its first hours of running is worth getting rid of. If I dont keep my Disco beyond a sensible ownership period I might not recoup the benefits..
...however if I fall on hard times & decide to keep my car I cant go back & put the minute amounts of metal that are worn off that make an engine old, back on. BREXIT - done properly.

hi,not to try and act smart or anything but both me and my dad are both experienced diesel fitters and have worked on plant, agricultural, comercial and industrial machinery for many years and we have always had this aproach to running diesel engines in. use it in a normal manner avoiding wide fast throttle openings, dont overload it, dont over rev it, dont idle it for long periods and change the oil every 250hrs or 500mls for the first 500hrs or 1000mls and from then on use it or drive it as per the use for witch it is intended. as for oil changes, i always change the oil on my vehicles every 6500mls (or 250hrs)witch some may say is over the top but for a diesel engine in industry thats about the general rule i have found, i supose it all depends on how long you intend to keep your vehicle. as for the turbo, you should always allow the engine to idle for at least 15 seconds to allow the turbo rotor to slow down and to cool but also so that when you turn the engine off the rotor does not spin for a few seconds whith no oil efectively running dry. 
thats my advice so, see you soon, jim
