I think, or rather it feels as if my 156 Twinny 1.6 is going a lot better in the cooler air. Sure she spews condensation and all that until warm, but once there, Bella feels aces.

Not really noticed the MPG though, may have to do a trip reset and have me a look-see:p

Also cold air is denser so contains more oxygen...

Which means taking it easy should keep mpg the same or improve it very slightly. If you drive hard it will use more fuel though as more oxygen is getting in same space so more fuel is added and you get more power out (it's why engine feels better - effectively earths own intercooler lol).

So combo of longer to warm, sitting waiting on windows to defrost at the start and hard driving and fuel economy can dip noticeably. But on 100-200 mile runs if you are not driving particularly hard I would suggest you may want to look for another reason for the change :)

I was going to post much the same - colder denser air should make more power, but, is that true if your car has a mass air flow meter which measures the mass (not the volume) of the air going into the engine?
