Interesting listening to the experienced pilots, I'm a new pilot myself with 100 hours now in 180 HP C172.
The 100LL at my airport is $6.84 a gallon and Sunoco 110 leaded is $7.45 gallon here and a lot easier to buy. So not a huge difference in price here.

My class delta home airport is a busy place right here in town so the price of fuel is higher than at the rural airports I noticed.
I fly at least once a week sometimes twice a week renting my flight school planes, they have 3 that I can rent. These are the 3 I fly.
