I have recently purchased a 3 L diesel sportbrake, 7 months old with 8k on the clock and was shocked to discover the oil at a dangerously low level after only having driven it myself approximately 200mls so either the dealer did not chech the oil levels before I took delivery or it is useing a phenominal amount of oil. The dealer informed me that diesel engines take a little while to run in and that the oil consumption should reduce over time but having had no such alarming experience with my previous 202L diesel Mazda I am a little sceptical. Can anyone out there reassure me that this is to be expected with an XF and that it will improve?
