Odd that it's not giving good economy, our 1.8 Weekend has always been outstanding for a petrol fuel car with so much room in it, one of the reasons it's still around 7 years after we got it. 35 around town and easily 40+ on a run. I imagine you have changed the air filter perhaps a can of injector cleaner would be worth a try. Also, have you got a lot of clutter in the car adding to the weight you are carrying about, or a roof rack on it<PS Our son in law had a 1.6 for a couple of years which they got becuase they liked ours, and the price you can get them for. It gave pretty similar MPG results to ours and one reason they got it was to lug stuff like roof tiles around while the were renovating a victorian house.
