During the recent colder temps I had noticed an increase in fuel consumption.However with the temps movin' into double figures at the weekend,
I started to get much better fuel usage again.

Another thing I've noticed that can make a difference, is to avoid roads with roundabouts
as much as possible.
Also temporary traffic lights can be horrendous on fuel consumption,
so if ya have temp lights on your normal commute,
try to avoid them using another route if possible.
Hill climbing isn't the best thing for economy either,
it's worthwhile planning a route to avoid inclines,
even if it makes the journey a few miles longer, it will make a difference.
Just my tuppence worth. (givin' away my age now)

Roll on the warmer weather.

Couldn't agree more. I've said so many times but most folk seem to disagree, quoting air density being higher at lower temperature, but whatever factors are in play I agree that hot weather gives far better mpg.
During the winter I've been getting mid-fifties (1.6 CRDi Eco SW) but one hot day got 76mpg.
I can _normally_ get near the 60mpg mark on average, but not in winter. It's easy in summer.

It won't.
You're just looking at the instantaneous reading, not the average which includes the downhill when you use no fuel. It is even technically not impossible for hills to work in your favour.

I do not use the instantaneous readout but use the average.I'm sorry but I must disagree with you there Ace Demon.

You obviously have your own ideas which you are entitled to, but I also have mine.

So in other words....

if you were to drive across Norfolk on a hot day the mpg would be awesome

Fair enough. It is common for people to make that error. Since you have made the assessment, what are your actual results?
