What causes drop in ...

[PeteH]

I have noticed our MPG always suffers when the temperature drops..
For instance, in January going to Spain we average 21.2 mpg
Coming home mid March it goes up to 22.5+ MPG

This has happened every year for the past 11 years .. and we are always heavier coming home than going

AH!! Well, It`s downhill coming back. Simples?

As a by the by, the trip of 250 miles to Blackpool on Monday saw a mpg figure of 25.4 !
Absolutely unprecedented!
Never seen better than 22.5 mpg before
