Apart from doing intermediate oil changes which are not part of the service schedule, does your car not give you a read-out on the speedo display of the km reading at which the next oil change is due, when you first switch on the ignition?
It varies depending on the usage the car gets and the type of driving it endures, apparently.
For example mine tells me I should change the oil at 12,000 miles (or before obviously).
Id agree with you jonan, and am still ignoring mini and changing at 6k! at that point the wife's roadster s turbo oil was very very black and i like to see nice clean stuff circulating; call me old fashioned but if you read the NAM threads on oil i'd say gut reaction/old fashioned is right!
I remember when 3,000 miles was the 'sensible' oil change interval and all cars had to be serviced that often.
For cars doing high speeds in Arizona deserts, I can believe that shorter intervals than Mini suggest might be good, but in Europe, I'm unconvinced.
Where are the huge number of work-out engines caused by the long oil change intervals? I suspect the answer is that they are in the same place as all the ones with worn-out starter motors caused by the stop-start....
I own a new MCS and asked the same question about service since I'm typically a low mileage driver but also live in a high altitude arid environment.
He said "Pay close attention to your onboard computer and adjust any fluid levels and tire pressure as indicated before making a service appointment to investigate the cause."
And then he added what I always believed was part of responsible ownership "Despite what your onboard computer may indicate, full service (including an oil change) should be provided at a minimum of once a year."
Algorithms are one thing... long term care is another.
Have to agree cruella there are inferences that Citroen with the same engines as the r56 had less trouble due to the shorter service intervals. For how little it costs me an oil change is a no brainer yearly. Then if I do decide to keep the car as I did with my mr2 (16 years 160000miles and still as sweet as sweet on 6 k oil change ) I know it's had the best chance .waste of money if you're definitely going to change the car regularly though.
