seems to be a lot of variation with MPGs on CMax models. I had an 04 1.6tdci 110BHP which did 40 - 55mpg. I had a mid life crisis and bought an X type Jag but got rid after a few months, bought a cheap Rover 45 (petrol) I recently 'saw the light' and bought an 07 CMax 1.6 tdci (90bhp) and made the following observation: Filled to brim, driven very carefully, 60 - 70 mph on open road, thinking ahead and avoiding braking and harsh acceleration. Drove 260 miles and re filled and noted amount of litres. Did the maths and worked out at 60.5mpg. Book figures are urban 48 extra urban 70 and average 60. The average MPG showed 65mpg. I think these displays are always a bit optimistic. When working out MPG, always do it by filling up and noting mileage, fill up next rtime and note miles driven and litres of fuel used. Divide litres by 4.55 to get gallons and divide distance driven by gallons used. I can do it in my head, saddo I know.
