I can get up to 14 m/litre on my car and its due to no special device I know my car I know the roads I take and I am constantly consciously "calculating" where I can us 5th gear instead of 4th or 4th instead of 3rd on what sections of road i can roll at 25 mph regardless of how flat it looks this make for fuel economy not this crap people keep trying to sell !
