Maintenance and care Calculating fuel economy 1. Fill the fuel tank completely and record the initial odometer reading. 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 fillĆups, 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 under current driving conditions. Additionally, keeping records during summer and winter will show how temperature impacts fuel economy. In general, lower temperatures give a deterioration in fuel economy. 236
