My mini dealer has set my computer to 25000 km to next oil change. Is this right. I've always used mobil 1 syn. and never gone more than 10000.

you dont say what engine you have???

if you want to change your oil before hand you can do..

my oil gets changed once a year regardless of mileage,max is 5-6k..

i don't beleive in these extended oil services..

The newest Mobile 1 extended life says 15,000 miles!
