Here's an interesting exercise using your Honda:

E0 MPG: 27, Highway (We'll assume the EPA rated mileage is using E0)
E10 MPG: 25, Highway (per your observation)

E0: $3.07/gallon
E10: $2.73/gallon

*these prices per GasBuddy.com at the station nearest me (ZIP 50309)

Using the above, we can calculate the cost per mile (or miles per dollar)

E0: $3.07/27 = $0.114/mi
E10: $2.73/25 = $0.110/mi

E0: 27/$3.07 = 8.79 mi/$
E10: 25/2.73 = 9.15 mi/$

So, as we can see using today's fuel example prices, you would have actually saved a bit of money using the E10 despite its lower MPG rating.
