Filling The Tank; Calculating Fuel Economy - Ford Escape 2013 Owner's Manual

The advertised capacity is 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 amount of fuel in the
tank after the fuel gauge indicates empty.

Filling the Tank

For consistent results when filling the fuel
tank:
• 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.
Results are most accurate when the filling
method is consistent.

Calculating Fuel Economy

Do not measure fuel economy during the
first 1000 miles (1600 km) of driving (this
is your engine's break-in period); a more
accurate measurement is obtained after
2000 miles - 3000 miles (3200 km - 4800
km). Also, fuel expense, frequency of fill
ups or fuel gauge readings are not accurate
ways to measure 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.
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. Calculate fuel economy by dividing
miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
Keep a record for at least one 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.
