Just because the topic comes up from time to time :

I Just received the latest bulletin from TOTAL.
AVGAS 100LL in France ranges from $7.11/gal to $7.99/gal with average
about $7.30. JET A1 is from $3.97 to $4.25/gal.

The FBO where I often rent in New York has just sent out e-mail to the
effect that they are removing their temporary fuel surcharge, because
prices have come back down somewhat. Wet rental of a 172SP there is about
$110/hr. Wet rental of a 172R outside Paris is $186/hr.
