Winter fuel (if you have it in your region) _is less efficient_ so your
mileage per gallon will decrease. Is that what you're saying?

I also see my fuel gage fall more quickly in colder months,
even though the mileage often stays the same. I keep an eye
for gasoline "adjusted" for winter. But I also think part of
the explanation is that in summer, cool gasoline is pumped
from underground into one's gas tank. Then it heats up and
so expands. This keeps the fuel gage reading higher,
compared to cold months, for awhile.

I've been recently noticing the same behaviour in my '04 Civic LX regardless
of the weather. And I just found a TSB about it on the EBSCO online
database, something to do with incorrect software specifications. The
solution is to replace the fuel gauge assembly. This applies to Civics with
the "Visteon" gauge assembly.

Looks like I'll be making an appointment with the dealer, and hopefully they
won't have to keep it and drive too long to see the symptoms themselves.

Fuel gages are only an indicator, no gospel by any means. Readings will
vary from car to car etc.

They can be notoriously inaccurate.
