fuelEfficiency

The distance traveled per unit of fuel used; most commonly miles per gallon (mpg) or kilometers per liter (km/L). * Note 1: There are unfortunately no standard unit codes for miles per gallon or kilometers per liter. Use $1 to indicate the unit of measurement, e.g. mpg or km/L. * Note 2: There are two ways of indicating the fuel consumption, $1 (e.g. 8 liters per 100 km) and $1 (e.g. 30 miles per gallon). They are reciprocal. * Note 3: Often, the absolute value is useful only when related to driving speed ("at 80 km/h") or usage pattern ("city traffic"). You can use $1 to link the value for the fuel economy to another value.
