That's terrible. I had a much bigger Mazda 5 with the same engine for a year and it averaged nearly 50mpg. Your problem could be a blocked air filter, it could be the diesel you are using (Shell V-Power or BP Ultimate are the best), it could be the turbo, it could be over-active regeneration of the DPF, or it could be your right foot.
Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
