"MPG IS A MEASURE OF CONSUMPTION"

- PAUL HORRELL

MILES PER GALLON ISN’T A MEASURE OF fuel consumption but of economy. A higher number means lower quantities of fuel used. Which is higher economy. This upside down way of looking at things inhibits our ability to understand how we use fuel and even how we might save it.

For example, do you know how much extra fuel a roofrack uses? Or aircon, or underinflated tyres? No, because you can’t just add their fuel to the car’s baseline when you work in economy, but you can if you work in consumption.
