Just a quick question about how fuelly calculates my mpg, with my current car i only ever fill it up with 20l at a time and then refill once the fuel light starts flashing at me and always have now would fuelly be calculated my mpg correctly this way if i dont enter it as a partial refil?
dont really want to chuck a full tank in to work it out as it seems too costly
