Fuel and Refueling • Turn the ignition off before fueling; an inaccurate reading results if the engine is left running. Use the same fill rate (low-medium-high) each time the tank is filled. Allow no more than two automatic click-offs when filling. Conditions • Heavily loading a vehicle or towing a trailer may reduce fuel economy at any speed. Carrying unnecessary weight may reduce fuel economy (approximately 1 mpg [0.4 km/L] is lost for every 400 pounds [180 kilograms] of weight carried). Adding certain accessories to your vehicle (for example bug deflectors, rollbars/light bars, running boards, ski racks) may reduce fuel economy. Using fuel blended with alcohol may lower fuel economy. Fuel economy may decrease with lower temperatures during the first 8-10 miles (12-16 kilometers) of driving. Driving on flat terrain offers improved fuel economy as compared to driving on hilly terrain. Transmissions give their best fuel economy when operated in the top cruise gear and with steady pressure on the gas pedal. Close windows for high speed driving. • • • Results are most accurate when the filling method is consistent. • Calculating Fuel Economy Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine's break-in period); a more accurate measurement is obtained after 2000 miles - 3000 miles (3200 kilometers - 4800 kilometers). Also, fuel expense, frequency of fill ups or fuel gauge readings are not accurate ways to measure fuel economy. 1. 2. 3. Fill the fuel tank completely and record the initial odometer reading. Each time you fill the tank, record the amount of fuel added. After at least 3 to 5 tank fill ups, fill the fuel tank and record the current odometer reading. Subtract your initial odometer reading from the current odometer reading. Calculate fuel economy by dividing miles traveled by gallons used (For Metric: Multiply liters used by 100, then divide by kilometers traveled). • • • • • 4. 5. EMISSION CONTROL SYSTEM WARNINGS Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Keep a record for at least 1 month and record the type of driving (city or highway). This provides an accurate estimate of the vehicle's fuel economy under current driving conditions. Additionally, keeping records during summer and winter show how temperature impacts fuel economy. In general, lower temperatures mean lower fuel economy. 142 F150 (TF6)
