the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
Your vehicle may be equipped with dual fuel tanks. If so, you will have a
selector control. For information on the Dual Fuel Tank Selector Control
refer to the
Driving Tips
section in the
7.3 Liter Power Stroke Direct
Injection Turbo Diesel Owner’s Guide Supplement.
Filling the tank
For consistent results:
•
Use the same fill rate setting (low — medium — high) each time
during filling.
•
Allow three automatic click-offs when filling.
•
Always use fuel of a known quality, preferably a national brand.
•
Have the vehicle loading and distribution the same every time.
•
When refueling a vehicle equipped with dual fuel tanks, if the two
tanks are not filled equally, the fuel gauge reading may fluctuate
slightly until the fuel level between the two tanks balance out and
become equal.
Your results will be most accurate if your filling method is consistent.
Note:
For vehicles equipped with dual fuel tanks, engine performance
may degrade if fuel is not added to both tanks when refueling.
Calculating fuel economy
1. Fill the fuel tank(s) completely and record the initial odometer
reading (in kilometers or miles).
2. Each time you fill the tank(s), record the amount of fuel added (in
liters or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank(s) and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. 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.
