Having checked my oil this morning, 3k miles in 4 months (autumn and winter). And it looks in the same state as oil in my previous 4x4 that did 9k in 4 months (May-September '17). Oil being done again in April or 2.5k miles to coincide with MOT and Pollen Filter. I would love a Citroen C Zero and use my Dad's car for longer trips but he wouldn't be best pleased.
