The service interval is calculated for the fuel consumption. Thats why all owners get different intervals. The fuel consumption is a good measure for service intervals, it takes into account:
# cold starts
driving in congestion, in country roads or Autobahn
driving hard or environmentally
only driver or fully loaded
winter or summer
