Going digital

Since I bought my first car I have always wrote down my fuel consumption and kilometers that I have travelled with my car. So today I downloaded an app to my phone where I can fill in the same information than in my little notebook. I am just adding the data of my present car fuel consuption from the notebook to the app. Let's see if I am a economic driver or not... only "few" times I have fillup my tank since I bought this car. I have been driven 47200km since 1st of March 2015 and I have used 3500 litres of gasoline.
