Maintenance and care 2. Each time you fill the tank, record the amount of fuel added (in liters or gallons). 3. After at least three to five tank fill-ups, fill the fuel tank and record the current kilometer (mileage) reading. 4. Follow one of the simple calculations in order to determine fuel economy: Multiply liters used by 100, then divide by total kilometers traveled. Divide total miles traveled by total gallons used. Keep a record for at least one month and record the type of driving (city or highway). This will provide an accurate estimate of the vehicle's fuel economy. Additionally, keeping records during summer and winter will show how temperature impacts fuel economy. In general, lower temperatures give lower fuel economy. Driving style - good driving and fuel economy habits Give consideration to the lists that follow and you may be able to change a number of variables and improve your fuel economy. Habits • Smooth, moderate operation can yield up to 10% savings in fuel. • Steady speeds without stopping will usually give the best fuel economy. • Idling for long periods of time (greater than one minute) may waste fuel. • Anticipate stopping; slowing down may eliminate the need to stop. • Sudden or hard accelerations may reduce fuel economy. • Slow down gradually. 164
