Hi all, i am considering the Mazda 5 in 2.0 petrol form 2011 plate, and wonder whether anyone has experience of that engine in their 6 for mpg please? Appreciate the 5 is bigger and heavier, but did the improvements made to this motor see significant gains at the pumps? We only do 8k miles per year, so the extra cost of 1.6d model is not justified. Thanks
