I can understand the mileage increase.

Since 'pure' gas tends to cost more per gallon; what has your cost per mile done?

Up?

Down?

Same?

I get 11% better mileage. The cost has been 8% higher.

In this area SW Missouri stations sell premium gasoline 91 octane as their ethanol free gasoline. It has been running about 24 cents per gallon higher than regular gasoline 87 octane E-10 (10% ethanol). The price differential ranges from 20 to 35 cents per gallon from station to station and will vary at the same station at times.

I have a drive of 160 miles round trip, on E-10 I was getting 18.4 mpg in my pickup. On premium no ethanol 20.6 mpg. Same road, same driving habits and speed.

The savings is not huge, but it has to be better for the motor.
