Simply driving the same route with the exact same fuel in a +2 celcius morning and measuring it against the same drive in a +15 celcius afternoon will measurably affect both your cars performance and fuel economy.

Well, I couldn't comment on air/fuel mixtures as I don't know much about that particular side of the coin. I could look it up though...

I suppose you could record the temperatures from your trip computer at the start and end of each journey... that would somewhat standardize the results or at least put them into some sort of context for those who do know about air/fuel mixtures.

What do you think British SD?
