Dense air gives you more power, so should give better fuel economy. However I think fuel injection does better in warmer weather, so it could overcome the former. Also the oil is thinner in warmer weather, thus better MPG.
Summer/winter gas definitely is a thing in the US.

dense air requires more fuel to get the correct a/f

Signs on every pump in ct clearly state something to the likes of. During the winter the gasoline at this station can contain an ethanol content of up to 10%

Anybody with flash pro, what is the lowest K.Control you have seen? (Indicates fuel quality) I'm at 54% on Shell 91 thankfully which is as good as it gets on pump gas Doug says. Is all American gas mixed with ethanol in the winter?
