In the modern climate fuel economy is becoming more and more important which is of no surprise considering the rising prices of petrol. Therefore people are becoming more and more conscious of MPG when it comes to buying a car.

What MPG is a little site that lists cars and how far they can go on a gallon of fuel, pretty useful if you’re looking for an efficient car, click here to take a look at their site.
