Perhaps the thread should be re-titled to read "Summer Fuel Efficiency......" My 61 reg Tourer has really come into its own in the past month with the warmer weather . I have a fairly light foot and virtually all my miles are on Motorways and A-Roads, generally at 60-65 mph, but my last three fill to fill consumption figures are as follows:- 58.09 58.88 61.66 My reaction to the 61.66 MPG figure was that the odometer must be inaccurate but measuring it against the mileposts on the motorway it seems spot on. I always use Shell fuel and have used the V Power Diesel for the last two fillups, taking advantage of the recent offer of 5 pence a litre off. On filling up again today I have gone back to the Standard Diesel so will have to see if the figure comes down again. Overall consumption from new is shown as 51.2 on the computer but is actually 54.4 using my spreadsheet. Can anyone improve on this?
