I tend not to fill the car up unless I’m doing a long journey as it’s just extra weight I’m pulling around when just in town with lots of stop /start and doing mainly short journey’s and the school run everyday, where the car don’t really get hot either, burns the most fuel.
On average i’d say maybe £20 a week. had the new car almost a month is a vitara 1.4 turbo mild hybrid only done 265 miles so far. Off to the beach tomorrow as daughter has inset day and my brothers this weekend a 380 mile round trip so guess I’ll know more then on the true mpg right now is around 30mpg.
