3rd tank with TMC box:
275.3 miles, only 36 litres used, and 34.7 MPG (stupid tourist traffic been holding me up recently)
Also, filled her with V-power today, only the 3rd time since having the car, and the 1st time since having the TMC box. Will let you know the results of both performance and economy in due time! First thing it affected was my wallet, £1.30 a litre!
