Another AX fellow
Welcome ! Have a look at my thread :

I have mounted 2 flow meters to measure the fuel consumption (volume only) but it's rather expensive and not really easy to mount. My '95 AX has a mechanical speedometer and according to Citroën Service, only the latest gasoline had an electronic sensor.
3,8 l/100 km is a good start but you'll see the AX has even more potential.
