Forgot about this thread.
Backfired a little as my 1st F10 M5 failed & was rejected, however i doubt my run-in procedure made one jot of difference
Replacement M5 arrived beginning of May & has now covered approaching 4k miles & oil level is still just under full. Most journeys are long motorway schleps but she was driven hard (isn) to/from Le Mans & has spent a day on track at Anglesey Circuit. Off for a 2 sayer at Spa in a few weeks with a few Nordschleife laps en route so i'll be keen to see how much oil she drinks over the next few weeks.
As per my initial M5, i didn't hammer the car for her 1st 500 miles but after that drove it how my mood & the conditions dictated;)

Just thought I'd post an update to this, in time for those who may be collecting new cars in a couple of weeks.
I bought my car new in March and have covered just under 8,000 miles in it since (including a weeks holiday up on the Isle of Skye where the car was absolutely in its element).
In that time the car has required just a single top-up, and this was quite soon after the 1,200 mile service. Since then the oil usage (according to the car) has been zero.
The engine feels absolutely rock solid and pulls like no other car I've ever driven. I'm collecting a new Range Rover Sport (diesel) on September 1st and am going to follow the advice as stated above in this thread.
So I was right then Andy, best regards J.I bought my car new in March and have covered just under 8,000 miles in it since (including a weeks holiday up on the Isle of Skye where the car was absolutely in its element).

PS) 10600 miles covered NO Oil used at all.
Mine has done just short of 17,000 miles and I have added 4 or 5 litres of oil over that time, which I didn't think was too bad, I ran both an E39 and E60 M5's from new and they both used a lot more oil...
(Andy M) I took deliver of a new RRS sport SDV6 in May so far its done 5000 miles and used no oil, I didn't follow any particular running-in procedure, although didn't hammer it. Best thing about it so far is that it's averaged 34 MPG from new, which for its size I think is good. It replaced a X5 3.0SD and never saw better than 26MPG.....

I've added just one litre in 14000 miles!
I believe that warming the car up over the first 1000 or so miles, using the rev range, but not hanging on at the higher end too long or hitting the limiter, makes a big difference.
The consumption quoted by some on here is just not right.
I appreciate cars are not all the same, but there should surely be more consistency between "well treated" cars?
Some figures are worse than with my old and much loved V10 M5!

There is a "fix" for this on one of the M5 forums, new later parts fitted and it seems to stop the Oil usage , I will try and find the link.I believe that warming the car up over the first 1000 or so miles, using the rev range, but not hanging on at the higher end too long or hitting the limiter, makes a big difference.

Just updating this thread with my oil consumption experience, just under 40,000 miles and I've still only topped up once with 0.25L. Oil is changed every 10k miles or their abouts (half the recommended interval) and it's not used anything measurable between changes since the one time just after the running in service.

I sincerely hope you guys are correct - I've followed both your recommendations
I did exactly the same and have racked up 45k flawless miles in mine now... my oil change intervals are quite high at about 16k but this will reflect the fact that I do a lot of motorway / long distance journeys so condition based servicing will vary.JMBMWM5 said:
Running in:
Warm Oil fully then for the first 40 miles or so; work the RPM hard too 5.5K up and down using gears to slow you, after that just drive normally within the running in range, always use the gears to slow you down, and if you can find some hills this would be even better.
Mine has used NO Oil in 5K miles using this method.

I voted 'Followed procedure - Low Oil Usage', which is true to the letter, I never exceeded 5,000 rpm and never applied too much throttle. Since the 1,200 mile service the car has used no oil at all in 3,000 miles.
HOWEVER, the first 50 miles or so are critical from what I know. It is very important to use the allowed revs and also to use engine braking as much as possible.
The reasoning behind this is that in the very early engine life the rings and bores need to be bedded in so there is no blow by. Engine braking causes a vacuum inside the cylinder that helps pull the rings into the bore and thus increases the rate of bedding in. Once the engine reaches 50-100 miles the bores become coated with varnish from the products of combustion which helps prevent wear, unfortunately if the rings and bores are not bedded in by the time the varnish accumulates they never will bed in fully, this will result in blow by which will increase oil consumption and reduce power slightly. If the varnish has accumulated and the rings/bores are not bedded in the only solution is to re-bore the cylinders and start the running in procedure again.
This is only my opinion based on a little experience and quite a lot of reading and discussion with knowledgeable people.
The best place to bed in an engine is on the track, not racing, just because you can accelerate in low gear using the full 5,000 rpm, then lift off back down to 2,000 rpm without the risk of someone running into the back of you because your brake lights did not come on.

So far mine has needed two litre top-ups, both about 3k miles before the service was due so in the region of 13k after a change. In both cases I've been near a dealership when the light has come on, and have just dropped it straight in as top-ups are included with the service package.
In hindsight I should probably have changed on half intervals as RichardM5 says above, as I expect to do 200k miles in this car.

Well done that man 
200k in an M5

I didn't realise some had a problem...
I followed the advise on runing including varying revs and taking to up to 5.5k every 3 minutes of driving. Made my wife sick!
Done 26k miles in it now after 16 months and had to put in 1L just before the 18k service. f
k me BMW charge a lot for the oil! I was pleased I ticked the service plan option when I bought it.
I too plan to drive it for hundreds of thousends of miles. Mostly with the traction light on this time of year...
