Just had 3yr old diesel transit serviced, only done 5000mls, had engine flush, oil and filter changed , but oil on dip stick is still blackish, have I been done, did have a another petrol car done at same garage and the oil was clean on that car afterwards.
diesels are bad for dirty oil in general,it may look bad but I would say that the majority would be like this after an oil change,just keep changing at regular intervals and you cant go wrong
