Re: Super poor fuel economy
When fuel light comes on you usually have 50mls fuel left . I think tank capacity is 50litres , near enough 10 gallons . Going by that , which is only a rough guide , you would seem to be averaging at least 28mpg . MPG depends on many factors , like type of driving , is it stop start town work , colder weather meaning longer to warm up , year and mileage of car , tyre pressures etc. etc . Could see if any sign of fuel leaks whilst engine running and also check fuel cap / seal .
