I went and filled up with some petrol this morning i left the keys in the ignition while i did as my missus was in the car listening to the radio, when i cam out i had got 2 miles down the road when i noticed my gauge still only had 2 bars on it and the miles said i had about 40 miles before i needed to fill up, over the next 20 mins it slowly rose to what i would consider a true level, hoever tonight, i had travelled somewhere and it said i had about 60 miles and 3 bars left ( did a lot of travelling today mind ) and then i stopped my car. Then started it up when i was setting off and the gauge had no bars and was saying i had no miles left in the tank???
