Re: why so use much petrol???
Mine does that aswell! I was going to post the same question! - Just sitting in the car with engine running the bloody fuel runs out! BUT! I dont think it truely runs out, because yes, the needle does rise very slowly when you get goin again. But then the next day its back up to where it should be.
When I bought my car, used, the very first time i fuelled it the needle didnt go up the the proper level, but after a while it did.
I think the 147s just dont like sittin down for too long/ or with the engine running!
..and i havent had air con on, heater, radio, etc, anything that would affect petrol, its just one those mystery alfa things!
