thats absolutely crazy, ive had the car now for just about 10,000 miles and its had 2 oil changes in that time, a new air filter, cabin filter, fuel filter and its about to have its second timing belt/water pump service and 4 new glow plugs, im hoping to get to 200,000 miles.
when i first did an oil chnage i was shocked to how dirty diesel engine oil gets, there was loads of tiny bits of carbon in, i pooped myself at first thinking it was metal.
