Disco 200TDI, with roof tent and gentle foot, averaged 28 MPG, just staying in front of trucks on the motorway and some minor road work, from Edinburgh to the South of France and back, included four people and all their holiday kit.
Regularly does the same from Edinburgh to Hereford and back, not sure how much oil it also uses, not a lot or I would have remembered.
Much better than expected.
