My 98 Mondeo V6 ATX (170 Hp Duratec) with 44000 mls on it did not require any additional oil between the 9500mls (15000km) service intervals. It went from full to well abow low on the dipstick in that distance.
My current 2002 Mondeo with same engine seems to use more. But I do a lot of Autobahn driving now, and I keep it a lot above 5000 RPM. I had to top off 1 quart after 10000 km (car has 14000 km on it now). But this may be due to the initial breaking in phase, I don't know what it will be in the long run.
