| How many miles does that give you Chris?
=A3100 @ 133p/litre =3D 75.2 litres =3D 16.56 gallons
In summer it does 29 mpg on long journeys, or about 27.5 pottering about/short journeys, so between 455 and 480 miles. In winter I'd be down at the low end of that range all the time (I think the diesel engine is over-cooled in our climate).
On a long trip I normally reckon on about 500 miles to an 80 litre tank-full, or 520 miles if I've been light-footed and I leave it till the little red light is really nagging at me.
I don't normally drive that fast - on the motorway I tend to set the cruise control to about 67 mph which is a tad under 2400rpm. If I up that to 70mph I lose at least 2 mpg, or maybe more, it's hard to be more precise. I guess that's not surprising: 5% more speed should reduce mpg by at least 10%.
The best I've ever had was 31.5, 32.1 and 31.1 mpg on three consecutive tanks full while on holiday in France. But that was on good diesel (it seems to like the Total Excellium stuff), in hot weather and driving in a seriously laid-back fashion on French "D" roads (top speed 50 mph).
