Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theMaintenance
product specifications and capacitiessection of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading may result if the engine is left running.
•Use the same filling rate setting (low — medium — high) each time
the tank is filled.
•Allow no more than three automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
•Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
•Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in miles or kilometers).
2. Each time you fill the tank, record the amount of fuel added (in
gallons or liters).
3. After at least three to five tank fill-ups, fill the fuel tank 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:

1Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.2Add the coolant type originally equipped in your vehicle.3Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated
for life. These lubricants do not need to be checked or changed unless a leak is suspected, service
is required or the axle assembly has been submerged in water. The axle lubricant should be
changed any time the rear axle has been submerged in water.4Service refill capacity is determined by filling the axle to 1/4-9/16 inch (6-14 mm) below the
bottom of the filler hole with the vehicle on a level surface.
Add 4 oz. (118 ml) of Additive Friction Modifier or equivalent meeting Ford specification
EST-M2C118-A, for complete fill of 9.75 inch Traction-Lok axles.5Approximate dry fill capacity including transmission fluid cooling system, actual refill capacities
will vary based on vehicle application and transmission fluid cooling system (i.e. coolers size,
cooling lines, auxiliary cooler capacities). The amount of transmission fluid and fluid level should
be set by the indication on the dipstick’s normal operating range.6Automatic transmissions that require MERCONV should only use MERCONV fluid or fluid that
is specified dual usage MERCON/ MERCONV. Use of any fluid other than the recommended
fluid may cause transmission damage. Refer toscheduled maintenance informationto determine
the correct service interval. Use of any fluid other than the recommended fluid may cause
transmission damage.7Service refill capacity is determined by filling the transfer case to the bottom of the filler hole
with the vehicle on a level surface.
