You should be getting a bit more than that. Can you do a more accurate check by filling up reset the trip counter and then check your mileage at the next fill up. once you know how much fuel you used to fill up you can workout your mpg.muzz said:I have a 57 plate 2.0TD auto Antara and my fuel economy is pretty shocking. Im lucky if i get 300 miles to a full tank. Id say im in the low 20s on mpg. I do mostly urban and 15-20 mile dual carraigeway runs at 65-70mph. I just assumed its a power to weight thing. Can anyone shed any light on it.
