    Poor fuel economy

    My astra seems to be using a hell of a lot of fuel. I'm only getting about 350 miles from a full tank, which works out at about 30 mpg. Don't know if anyone else has a problem with poor economy, its a standard 1.8 sri. Anything I could do to improve it? i don't drive it that hard either.

    What sort of driving do you do? I do 250 miles on motorway/A road and 50 in town and average about 30mpg. It's the sprint gearing that does it, it revs far too high. 80mph in fifth is about 3600rpm.

    Edit: Mine is also a standard 1.8SRi

    I can get 450miles just about on full tank, (thats drive very carefully)
    On average i get 350 to 400miles
    I have 1.8 Sri, 3 door and standard.
    Drive around countyside and town roads.
    Sounds daft, try not revving hard and easy on the accleration.
    See how that goes

    To be fair i do alot of stop-start driving to work, it's only 5 miles half of which is town and half countryside. Maybe it does sound about right for the type of driving i do.
    The daft thing is the fuel gauge only seems to drop when i turn the ignition key, and it does drop a fair bit.

    If I use the country roads for work rather than the motorway fuel consumption is up to about 35. When I go out to Norfolk 300 mile round trip I can generally get 35+
