2013 FORD F650 fuel

Fuel Filler Cap
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
WARNING:If you do not use the proper fuel filler cap, excessive
pressure or vacuum in the fuel tank may damage the fuel system
or cause the fuel cap to disengage in a crash, which may result in
possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel system if the correct
genuine Ford, Motorcraft® or other certified fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a
14–turn on and off
feature. When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise a
14–turn until it clicks at least once.
If the check fuel cap light appears in the instrument cluster and stays on
after you start the engine, the fuel filler cap may not be properly
installed.
If the fuel cap light remains on, at the next opportunity, safely pull off of
the road, remove the fuel filler cap, align the cap properly and reinstall
it. The check fuel cap light may not reset immediately; it may take
several driving cycles for the indicators to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by normal city and highway driving.
FUEL CONSUMPTION
Filling the Tank
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.

Note: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 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.
•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 balances out and
becomes equal.
Note:For vehicles equipped with dual fuel tanks, engine performance
may degrade if fuel is not added to both tanks when refueling.
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 2000–3000 miles
(3200–4800 kilometers). 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 as follows:
•Standard: Divide miles traveled by gallons used.
•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 shows how temperature impacts fuel
economy. In general, lower temperatures mean lower fuel economy.

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM (DIESEL
ENGINE ONLY)
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of Maintaining the DEF Level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled before the DEF
gauge in the instrument cluster reaches the first low level warning
(seeWarning messages and vehicle operations).
The engine control unit monitors the amount of fluid available in the
DEF tank. Failure to maintain an adequate amount of DEF in the system
generates warning messages that appear in the information display and,
unless the DEF tank is refilled, leads to a forced reduction of engine
operations.
Warning Messages and Vehicle Operations
The instrument cluster contains a DEF gauge and indicator lights to alert
you to any low DEF level conditions. The indicator lights illuminate if the
DEF gauge level drops below 0.5 gallons (1.9 liters) in the 5 gallon
(19.0 liters) DEF tank or 1 gallon (3.8 liters) in the 9 gallon (34.0 liters)
DEF tank.
Upon filling the DEF tank after a low level warning, normal operation
resumes when the vehicle is restarted.
