Gilders , as I have previously said I drive kia xceed 1.4tgdi and was only getting 29 mpg but recently i’ve started putting in premium petrol and driving a bit more considerately and have been achieving 37mpg on 2 to 3 mile journeys so am hopeful of say 35mpg with the mhev 1.6tgdi . I even got in the 40’s on a quick run down the motorway so i’m not as fearful as I once was .
