    Can any one shed any light on my situation. When I put fuel in my car, the fuel gauge will go up, but as I drive the car the gauge doesn't seem to fall at all???

    If it doesn't seem to fall at all, how does it go up when you put fuel in?

    As above:
    How do you know it goes up, if it never goes down for you to refill it and see if it goes back up? :dk:

    It had quarter tank in it the other day so I put £30 in it and it went up to 3/4, after 2 days didn't move and have just put another £40 in it and now sayin 1 bar below full, just been up the motor way and back and it's not moved at all

    You're not driving it hard enough :devil:

    Try using some fuel system cleaner, or fill up with V-Power.
