If I figure correctly, in USA terms that is about 33 MPG. On a long trip I have gotten 40 MPG, but generally I am getting 30-39 MPG. With a 2011 GLS. I have check the computer MPG against paper and pencil and they are pretty close. Maybe only a gallon to two apart.
10% ethanol reduces fuel mileage by about 10%. I've done the real world checking and verification. Funny thing is, if you crunch the numbers you'll learn we're actually putting MORE harmful gasses into the atmosphere because of the reduced efficiency.... the gas has 10% ethanol, which I hear increases the cost and decreases the mileage.
