Subaru legacy 2.5, 480 miles in 6 hrs dead on A roads + 32.7 mpg (Low 20s around town though)
In my wifes 1.5 diesel megane you can top 70mpg keeping to low revs + 60mph max

turining the air con off makes a significant difference - I'd say as much as 3mpg.
On the acceleration, I made a point of using the diesel torque to accelerate the car very gently and keeping the rpm below 1500 means that the turbo
never spools up therefore minimising fuel consumption. The turbo spolls up at around 1800rpm on my TDI.
Hills make a significant difference too. I was using gentle acceleration down hill to build extra momentum and minimise fuel use climbing back up the
other side.

My best was 647miles on 1 tank of diesel (fill to fill) in my '51 plate 106 Diesel. I calculated it to be over 70mpg.
This was commuting from Woodbridge to Colchester, including hitting rush hour traffic. Driving slowly on a very busy dual carrageway is quite
scary..!
Diesel Rules!
A couple of months back I took my petrol 106 down to Burnley that was just over 223 miles each way
on the way back:
168 miles of mostly clear M6 / M74 (about 60 mph average)
then 39 miles of twisty back road (about 4500-5000 rpm average and 3rd gear most of the way)  
then 16 miles of dual carriageway
it managed 51.4 mpg
I'm pretty happy with for a car that has only 4 gears, a carb, 8 valves and the clock hit 100,000 miles just before the return trip
I'm especially happy because I wasn't even tiring
about 4 years ago (with the same car) I managed about 62mpg crawling up the A9 despite having 5 people in the car (and all their drink + stuff for a
week) - that was not a fun trip, ~950 miles in a 3dr 106 with 5 people

Don't go too fast and dont brake are the key factors
Sorry I crashed into that car officer, you see, I was saving fuel
The trick is to observe the road and lift off the accelerator so that you natrually slow rather than having to use the brakes, not to grit your
teeth and brake the speed you have.
Jeremy Clarkeson said recently that he has never braked on a motorway - he observes conditions instead. I don't believe him of course but he
makes the right point.

My passat 110 tdi used to do 60mpg without trying then i put 17's on it with the wrong tyres. It does 52 now unless on a run then steady 70
driving just off the throttle itl do 60mpg. 65 if i sit at 60mph. My old wheels (15's) i used to get it to 70 - 75 on a run. It still did 40
when my locost is on the trailer behind. Havent towed it any distance with the 17s on yet.
My fiesta zetec-s i had before it used to average about 18 which no one believed. sposed to do 30. If i really tried to get the mpg up it actaully
went down. The induction kit i had on it made it better.

My mate in NI had a saxo 1.5d. It used to average 80mpg and he used to run it on red diesel so u can imagine how much it cost him to run.. 8 quid to
fill the tank i think he said.

Some how I doubt that. The official figure is 58 MPG if memory serves. 80 sounds a bit high to me.

my 54 plate vectra cdti 150 over the last 14,000 miles has managed an average of 40 mpg but apparently they over read by 5 mpg so 35 mpg aint bad.
i've started saving for a 170 bhp leon fr though
bet that wont be as good lol
