you could extrapolate that schedule out beyond 60K miles by going back to the third year and starting over although personally i'd never leave the oil in that long and never have.
also, you ought to consider an appropriate interval for things labeled as "life-time fill" by BMW, bearing in mind that BMW defines "life-time fill" as the life-time of the component (your DCT for example) cooled/lubricated by the "life-time fill", ending when the component ceases to function due to failure to service it, at which point you must purchase a new component from BMW. the new component, however, will of course come with a new "life-time fill", so not to worry.

(stop watch on for hysterical comments claiming DCT never needs service because it's an "automatic".)
so when do you recommend for DCT transmission oil change? Sounds like its a bad idea to let the component fail due to never changing out the oil.
