    What sort of MPG should I be getting?

    Hello everyone, I'm new to this forum so forgive me if this is not the correct place to post this thread.

    I've just bought a 15 month old Astra (G) Convertible 1.8 16v and am not really that impressed with the MPG its returning. The car I had before it was a Renault 19 Convertible 1.8 8v and that seemed to do a lot more mileage between petrol stops!

    Thing is I went for the 1.8 as I was after something economical to run but considering how guttless the cars is I may have been better off with the 2.2 litre.

    Anyway, let me know if this makes sense, I filled her up to the brim, drove exactly 200 miles of mostly town use with short journeys etc where engine not really getting warm plus a bit of motorway with 45 mins of stationary waiting for accident to clear. Filled her back to the brim and she took exactly 30 litres of unleaded.

    So 30 litres = 6.59 gallons
    6.59 gallons divided by 200 miles = 0.03295

    So that equates to 33mpg right??

    This figure doesn't seem that far from what the book says for urban driving so maybe the car is ok.

    What exactly is extra urban in the book anyway as that figure is higher??

    Thanks James

    Hi and welcome I have a 2.2 coupe, my travel to work and back is 12.5 miles on a 40 mph road with some traffic lights... mine returns about 33 mpg.

    it can also depend on how heavy your right foot is

    None of the petrol Astras are particularly stunning when it comes to fuel economy.

    Then again, I get 41mpg in the city with my 2.0DTi, though it'll do well over 55mpg on long runs on A-roads or motorways. It's also fit for well over 120mph if you're silly enough to try.

    Thanks for replies lads, I shall carry on monitering this to get an overall average. Just for the record I dont really boot it as it would be a waste of fuel. A 1.8 in a convertible which weighs considerably more than its hard top counterpart simply wont move any faster than it wants to regardless of how hard your foot is pressed on the pedal!!!

    Its just for poodling around in with the roof down really. If I want serious acceleration I leave the Astra at home and take the Fiat Coupe 20v Turbo instead..

    Yeah, but the 1.6 cab is just a glorified skip in relation to performance...
