Running Out of Fuel NOTE: Avoid running out of fuel because this situation may have an adverse effect on modern powertrain components. You may need to crank the engine several times before the fuel system starts to pump fuel from the tank to the engine. Fuel Economy Fuel economy is an estimate of the efficiency of your vehicle, and can be calculated as Miles Per Gallon (MPG) or Liters Per 100 Kilometers (L/100K). Do not calculate fuel economy during your vehicle's break-in period. This would not be an accurate estimate of how much fuel your vehicle will normally use. To calculate fuel economy: 1. Fill the fuel tank completely and record the initial odometer reading. 2. Every time you buy fuel, record the amount (in gallons or liters) purchased. 3. After at least 3-5 tankfuls, fill the fuel tank and record the final odometer reading. 4. Use these equations to calculate your fuel economy: s English: MPG q (total miles driven) Ȗ (gallons used) s Metric: L/100k q Multiply the number of liters used by 100 and divide the answer by the number of kilometers travelled. 308
