it will be always at the back of your mind whether the oil will damage the engine or not - it almost certainly won't but why have it hanging over you?
ok, i misread - a bit more than £10 but less than one tankful.

A Friend of mine has a 2006 BMW M6. He is looking for oil and will only look at Castrol 10 60 as it states in his service book to use Castrol. He
needs 10 litres and it is £48 for 4 litres on opie oils.
There is some Fuchs on there 10 60 fully synthetic for £36 quid for 5 litres.
Would any of you's be happy putting the Fuchs in??
a quick look shows a 06 M6 is a £ 15k+ car - why quibble over £ 10!!!

Any 10w/60 synthetic will be made from base stock with a high percentage of ester base stock.
Ester based synthetic engine oils are blended from the limited range of ester base stocks and compared to mineral oils have only very low levels
of additives, so one ester based 10w/60 is going to very similar to another.
AGIP do a 10w/60 racing oil which is a bit cheaper.
Carlube Triple R 10w/60 fully synthetic is much cheaper, however the percentage ester base stock in this oil will be much lower and a higher
percentage of the blend will be "cracked" mineral oil which after cracking is classed as a fully synthetic oil,
The ammount of aditives added to the blend will be higher.
Not to be confused with old fashioned mineral oils or "semi"synthetics there is nothing wrong with synthetic engine oil made from
cracked mineral oil stock provided the manufacturers service intervals are adhered to.

Castrol is the last oil I would ever choose.
Mobile 1 is the top big brand,
.
Without sounding silly, he's bought an m6 and is trying to avoid using the oil BMW say to use on a 8000rpm v10? That 40-60 quid saving might end up hurting.

The Castrol will have a specific BMW specification number if BMW recommend it, so check if the Fuchs also complies with this standard. If it does
then jobs a goodun.
Fuchs/Silkolene make top quality oils, as long as it meets the requirements I would have absolutely no hesitation in using it.
M6 is a great example of a car that many people could stretch to buy but very few could afford to run. My mate bought his for 18 grand, and I reckon he has spent the same again in the first year of ownership just running and maintaining it. The sound though is unreal, as he has a sports exhaust on it.
The answer is use Castol only with this engine!!
I run an 2007 M5 and having talked to lots of owners and specialists and they all use BMW recommended oil for apparently some well documented reasons
to do with specific additives. I'm usually sceptical with these sort of things but a 5.0 561bhp NA asparated motor which I've done 18k
miles in during the last year, well why penny pinch or not follow common practice?
I buy the oil, and these V10's use a good bit of it, from GSF as they always have an 'oil' code for discount of 35% or so
They do sound spot on with a sports exhaust - you can spend a long time on YouTube finding out if you've not already done so! 
They all come with a slight gash gearbox though don't they, although IIRC the Americans managed to convince they to supply a manual which is a
bit ironic given they usually prefer slush boxes so they can have a 64oz soda in one hand etc whilst driving

No he's quite happy to use it and spend the money. It was more me asking "why only Castrol". There must be other oils out there just as good or even better than Castrol and why do castrol only sell 4 litres when most others sell in 5 litres??

To answer a few of the questions......
The SMG gearbox (manual), despite what others write, is absolutely sublime. I can only think that they don't understand how to drive it, so post
crap opinions which simply aren't correct? Sure it can be a little clunky around town (I never use it in auto) and the diff is quite locked up
so its a little graunchy at low speed maneuvering. However, 7/10ths pace and above pace, 8250 RPM and a throttle blip to shift gear and you realise
that the M engineers have designed this to do what it is supposed to do brilliantly.
As to running costs, I've had to invest in standard consumables apart from it will need discs and pads soon (£2k) it has had a clutch and
flywheel £2.2k and new set of tyres all round cost me north of £1k recently but this is probably only 30 - 40% more than a 535d would cost for these
items and it is WAY more fun.
I had the limiter delete and quite a costly remap, but what a massive difference that made! I have a Hayward and Scott exhaust on it too, so it does
sound pretty epic, except on cold start when I'm trying to sneak of the drive at 06.00
Fule consumption is pretty good really, for a car with this performance. I really don't mind the consumption one bit, but the range I HATE! The
VERY VERY VERY annoying thing with the M5 is the ridiculously small tank, meaning I can get 200 miles range at best!!!!!!!

Not a fan of the autos, iirc you have to go a lot newer to get a double clutch one. But you have to get a much older m5 to get a proper manual.

How do you find running on a daily basis, any major hits for repairs yet?
Always fancied one even if only for a year, I only do 6k a year so mpg not a big issue

Id love to get used to one, but I've only managed to get a few drives in it! All I could say is its very different to other autos I've driven, difficult to manoeuvre as you try to find the bite point. Proper sick car though, if you can live with 14mpg. My mate used 3 tank fills in a trip to Scotland recently!
The reason why all manufacturers are very specific about approved oils these days is all to do with meeting emissions requirements, in the USA
manufacturers are required to warranty cats and other emission related parts for 7 years.
To certify this they run extended tests on engines running the specific oil as a result only 2 or 3 oils are actually approved by the manufacturer
although other oils may meet the manufacturers spec they will not have been actually tested by BMW hence can't be advertised as approved.
