I recently purchased a 2015 Vauxhall Astra 1.6 Exite, I would like to know how I can find out the average fuel consuption of my car. I have checked the menu on the vehicle and all that it shows is the trip, total miles driven on the car, tire load, tire learn and oil percentage. I have tried everything that I can think off and I have searched through the owner manual of the car but I have been unable to find a way to show me the average fuel consumption. Any help would be greatly appreciated.
