The distance traveled per unit of fuel used; most commonly miles per gallon (mpg) or kilometers per liter (km/L).<br/><br/> <ul> <li>Note 1: There are unfortunately no standard unit codes for miles per gallon or kilometers per liter. Use <a class="localLink" href="http://schema.org/unitText">unitText</a> to indicate the unit of measurement, e.g. mpg or km/L.</li> <li>Note 2: There are two ways of indicating the fuel consumption, <a class="localLink" href="http://schema.org/fuelConsumption">fuelConsumption</a> (e.g. 8 liters per 100 km) and <a class="localLink" href="http://schema.org/fuelEfficiency">fuelEfficiency</a> (e.g. 30 miles per gallon). They are reciprocal.</li> <li>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 <a class="localLink" href="http://schema.org/valueReference">valueReference</a> to link the value for the fuel economy to another value.</li> </ul>
