I drove from Pueblo to Winter Park and back last summer on one tank of gas (the fuel light turned on as I was pulling into Shell). I did the math and I averaged 21.6 mpg on that trip. I don't usually fill the tank, but I estimate I average around 17-18 around town with 91 octane Shell gas, and 15-16 with everyone else's 91 octane.

 

We'll see how that changes when my AC lift is done. Almost there, just the rears and an alignment and I'm good to go.
