Xantia 1.8i 16V fuel consumption?

I moved to France to live at the start of the year and in mid February bought a 1998 1.8i 16V Xantia. When we bought the car it had 129,000km on the clock; it has about 144000km on it now. I got it from a good garage, it has been properly looked after and serviced and, as far as I know, there are no faults.

The query I have is regarding fuel consumption. I have calibrated the distance shown on the odometer against motorway posts and have found the odometer reads 4% fast. So that's reasonably ok. I drive the car until the fuel gauge is down to about quarter-full then I fill the car to the brim.

I confess that I do drive very carefully - hardly any acceleration, coasting wherever I can safely do so and generally anticipating events so that I brake as little as possible.

Allowing for the 4% error and correcting litres to UK gallons and km to miles, then over the whole distance I have had the car it has achieved 42mpg. On a return run from my home here to Birmingham (very large amount of motorway) the fuel consumption was 48mpg!

What do others get?

That sounds better than average to me, I used to get 38-40 around town, and up to 45mpg on a long motorway

My Xantia was also a 1.8i 16v 1998 model (dimension)

I must be doing something wrong then as I'm on my second 1.9TD and neither has given more than 45mpg.

I have about a 42 mile return journey to work mainly motorway at a steady(ish) 65mph and that returms about 42mpg.

I usually get less than 30 mpg in my 1.8i 8V Xantia, but that is on short runs.
I haven't gotten much more than 37 mpg even on long runs with cruise control.

The 8v engines seem to be considerably less economical than the 16v versions, My 2.0i 8v Synergie is getting about 23mpg around town, and about 28mpg on a run,
Its getting LPG converted in the near future otherwise i will be bankrupt trying to run this mpv !!

Thanks, repliers. I'm reassured that these cars are well capable of returning well over 45mpg on a long run. Much more should be made of this remarkable figure for a decent-sized 5 seat saloon.
BTW, second hand cars in France generally hold their values better than in UK. Even given that this is a really nice car, 5 excellent Michelin Energies, good service and pretty well faultless, over here it cost €3500 or about £2400. I suspect more like £1200 in UK!
