I guess you could say the same for posters that are 'belittling' the manufacturers for their service schedules 
. Seeing as they designed, developed and produced the cars in question, I think they are probably better placed to advise us than a bunch of blokes on the internet.
They do get it wrong sometimes - e.g. "filled for life" autoboxes on Mercedes a few years back. They later back-tracked and introduced every 40k changes after they started breaking. .

It might be driven gently or ragged on track-days. Only you know how you use your car, what's wrong with using your head?

If it takes you an hour to change your oil then you're doing it wrong 
Not always, you want to see the crap in the way on some of these Eco boxes, undertrays etc to help with drag and such forth, nightmare.
tty software trying to tell the onboard computer it's had a service! Depend on engine but my audi takes 10 litres of the good stuff too, not cheap.
I've done well over 65k in 22 months with 18-20k service intervals (just do what the car tells me, no clue how it works it out) and no horror stories. Couple of thousand to go till next service!
The car has correctly been identified as a Mini Cooper S.
I think I will get the oil change done at Mini.
It gets me an extra stamp in the service book for when I sell in 12 months time, and a chance for them to look at the car for any warranty work / recalls.
The £149 will almost certainly increase by at least £30 for the obligatory plug in to the diagnostics machine.
As previously stated the car has used a few litres of oil (~3L) over 12 months, so it's probably 50% fresh oil anyway.

That's an either or statement, if you've not been ragging it then not, if you have then its not a bad idea.
Some modern cars have water pumps that run after shut down to help cool the Turbo, Cooper s for one.
What about the turbine shaft still spinning with no oil supply? (That sounds sarcastic, but it's not meant to be).Some modern cars have water pumps that run after shut down to help cool the Turbo, Cooper s for one.
To be safe I count to 10 as a minimum. Costs nothing and really doesn't spoil my day.

My understanding was that letting a turbo idle for a bit before switching off hasn't been required for yonks - unless you've been ragging the tits off it.
Which is why I stated " motorway " stops as an example. If your car's turbocharged, you can almost guarantee the turbo's been spinning for the duration of time you've been driving on the motorway. And letting it continue to spin with no oil supply because you haven't given it a moment to cool before switching off to put fuel in, etc, is detrimental to it's long term health. MG CHRIS said:
Being a mechanic ive seen the problems of long life servicing and lack of oil changes it can do a lot of damage to the engine, various manufactures have problems with oil problems.
The most famous one is the corsa timing chain rattle caused by lack of fresh oil this week infact ive seen a corsa in with low compression due to only having 1 oil change in 4 years the oil was like tar.
Mini also have the same problems with the chain tensioner too, also the mazda 6 diesel engine but that to do with failed regens on the dpf dumping fuel into the oil.
Another case is the utterly woeful 1.6 hdi pug lump found in various cars. They suffer a lot of problems that would have been cured by more regular oil changes. On this engine the injector seats are known to chuff if this goes un checked unburnt carbon enters the oil. Oil thickens up over time and blocks the small gaze in the turbo oil feed line this results in the turbo running dry of oil that interns destroys the turbo and if carried on driving will kill the engine.
This also can happen without the chuffing injector seat oil gets thicker over time and does the same thing also it isn't helped by short journeys.
20K service intervals are only set for the rep market they will last 3 years then as soon as they are sold on the manufacture doesn't want to know about them. Outside of the typical rep car service intervals on more run of the mill cars are around the 10,000 mile mark.
Most mechanics I know don't believe in long life car servicing as we see what or can become of cars that are on it. Know I will admit that some cars will be fine on it and we only see cars that comes in with faults which is fair enough but a lot of the problems come down to lack of servicing or even a basic oil change.
A oil and filter change on my car cost £20 for me with my mx5 mk1 it gets changed ever 6000 miles or once a year as I don't do high mileage the engine will last well over 250,000 miles.
In fact most engines will do this sort of mileage with regular oil changes, the oil is the most critical part of your engine why wouldn't you want to make sure its a fresh as it should be, ive seen the condition of oil coming out of longlife serviced cars all I would say is I wouldn't want that lubricating my engine.
Finally some common sense from someone else with a background in the trade. Good post.The most famous one is the corsa timing chain rattle caused by lack of fresh oil this week infact ive seen a corsa in with low compression due to only having 1 oil change in 4 years the oil was like tar.

I'd like to see your evidence for that one as well. AFAIK the USA has been on extended oil change interval for at least as long as UK. And they were certainly in first with the light 30 and now even 20 weight synthetics.
No Siree, the USA was well behind Europe in long drain engine oils. That's my experience after working for many years in the Lubricants Division of the largest oil company. Clearly remember ferrying a senior American colleague in my, then, Mk 1 Fabia vRS. He couldn't believe it was a diesel and relatively quick and thought 9000 mile oil change was outrageous. USA was slow to adopt because oil changes were dirt cheap.......and still are.Heaveho said:

Don't think you need to worry about this on modern turbo charged cars.
Yes you do, especially on the op's mini, one of the recalls is a heat wrap that goes around the oil feed pipe, heat build up from the Turbo is carbonising (is that a word) the oil inside so eventually it blocks the line and starves the Turbo of oil, result one fecked Turbo.IMO unless the thing's glowing hot after a serious blast it's not going to come to any harm these days. Most people slow down for at least a few minutes before they park and switch off, which gives the turbo time to cool a bit. Saab must have been turbo-charging their engines for 30 years but there's no sign they disintegrate every 10 minutes.

And even then they'd changed the oil filter halfway!
