About these numbers
EPA ratings come from standard laboratory tests adjusted to reflect real-world driving, so they are best for comparing vehicles. Your own figure will vary with speed, temperature, load, tires and driving style — measure it with the MPG calculator. If you have fitted larger tires, correct the reading with the tire size and fuel economy calculator.
