i just did a 200 mile trip to the cotswolds, cruising on the motorway mostly and got just 23mpg.
albeit there was a passenger, a boot load of gear, oh and a little box trailer
but still it's fairly rubbish by your standards! great by mine tho as my around town pootling generally gets me 18mpg!
Last time i hit 30mpg was for a couple of miles on a motorway once when the moon was blue
average is 25 i recall! no lpg for me either!
Debs - what's the secret!? I know i'm heavy round town but still, the crusin should be over 30 shouldn't it? :-/
Surely yes!

....I`d be gutted if I couldn`t keep above 30 MPG on
any journey!
I`ve found 65 MPH gives the right balance of progess versus economy.
I keep tyre pressures at (rather) the high end of the load-scale and the tracking is spot-on.
Regular oil & filter changes and keeping those 'breathers' clear.
Use only [size=16]really[/size] gentle acceleration (allowing time for the car`s mass to 'catch up with the slowly increasing throttle setting').
Use downhills for overtaking on m`way where safe/possible and 'reading the road' to conserve kinetic energy of car in bends rather than harsh-braking and wasting that £1.07/litre fuel just to heat the brake-discs/tyres.....
All a bit
'sad' isn`t it?.....but as petrol is now priced as a luxury, anything to make it stretch-out has to be good!

As I noted, for me it`s an
economic-driving game; `to pass the time on boring trips (and save a bit of money too!).
