Fuel Consumption; Filling The Fuel Tank; Calculating Fuel Economy - Ford Mustang 2016 Owner's Manual

Note: A fuel spillage concern may occur if
overfilling the fuel tank. Do not overfill the
tank. The fill pipe is equipped with a drain
hole. Excess fuel due to overfill may drain
through the drain hole and drip onto the
ground.
If the fuel fill inlet was not properly closed,
a service engine warning lamp may appear
on the instrument cluster.
At the next opportunity, do the following:
1. Stop your vehicle as soon as safely
possible and shift the transmission into
park (P).
2. Switch the ignition off.
3. Open the fuel filler door and remove
any visible debris from the fuel fill
opening.
4. Insert either the fuel fill nozzle or the
fuel fill funnel provided with the vehicle
several times to allow the inlet to close
properly. This will dislodge any debris
preventing the inlet from sealing.
If this action corrects the problem, the
message may not reset immediately. It
may take several driving cycles for the
message to turn off. A driving cycle
consists of an engine start-up (after 4 or
more hours with the engine off) followed
by city or highway driving. Continuing to
drive with the message on may cause the
service engine soon lamp to turn on as
well.

FUEL CONSUMPTION

The advertised capacity is the indicated
capacity and the empty reserve combined.
Indicated capacity is the difference in the
amount of fuel in the fuel tank and when
the fuel gauge indicates empty.
See Capacities and Specifications

Fuel and Refueling
Note: The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Note: When refueling your vehicle after the
fuel gauge indicates empty, you might not
be able to refuel the full amount of the
advertised capacity due to the empty
reserve still present in the fuel tank.

Filling the Fuel Tank

For consistent results when refueling:

•
Results are most accurate when the filling
method is consistent.

Calculating Fuel Economy

Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine's break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km) to 3,000 mi
(4,800 km). Also, fuel expense, frequency
of fill ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1.
2. Each time you fill the fuel tank, record
3. After at least three fill ups, fill the fuel
4. Subtract your initial odometer reading

I n f o r ma t i o n P r o v i d e d b y :
Always switch the ignition off before
refueling. If you leave the engine
running, you will get an inaccurate
reading.
Use the same fill rate
(low-medium-high) each time you fill
the tank.
Allow no more than two automatic
shut-offs when refueling.
Fill the fuel tank completely and record
the initial odometer reading.
