2012 FORD F550 fuel cap

• Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
• Resting your foot on the brake pedal while driving may reduce fuel
economy.
• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
• Use recommended engine oil. Refer to Maintenance product
specifications and capacities in this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in scheduled maintenance information.
Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
• Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
• Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
• Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
• Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
• Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
• Close windows for high speed driving. Maintenance and Specifications

Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult your Warranty Guide for complete emission warranty
information.
On-board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When the service
engine soon indicator illuminates, the OBD-II system has detected
a malfunction. Temporary malfunctions may cause the service engine
soon indicator to illuminate. Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel cap may not have been securely tightened. See Fuel filler
cap in this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly tightening the fuel cap or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon
indicator should stay off the next time the engine is started. A driving
cycle consists of a cold engine startup followed by mixed city/highway
driving. No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon indicator on can
result in increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and lead to more costly repairs. Maintenance and Specifications

EXCEPTIONS
There are several exceptions to the Normal Schedule. They are listed
below:
Normal vehicle axle maintenance: Rear axles and power take-off
(PTO) units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3,000 miles (4,800 km) or three months, whichever
comes first. This interval can be waived if the axle is filled with 75W140
synthetic gear fluid meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles (refer to Maintenance product specifications and capacities in
the Maintenance and Specifications chapter for details).
Police/Taxi/Livery vehicle axle maintenance: Change rear axle fluid
every 100,000 miles (160,000 km). Rear axle fluid change may be waived
if the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent.
Add four ounces (118 mL) of additive friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle fluid should be changed anytime the axle has been
submerged in water
California fuel filter replacement: If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the vehicle’s
useful life. Ford Motor Company, however, urges you to have all
recommended maintenance services performed at the specified intervals
and to record all vehicle service.
Class A Motorhome: Change brake fluid every two years.
Hot climate oil change intervals: Vehicles operating in the Middle
East, North Africa, Sub-Saharan Africa or locations with similar climates
using an American Petroleum Institute (API) Certified for Gasoline
Engines (Certification mark) oil of SM or SN quality, the normal oil
change interval is 5,000 miles (8,000 km).
If the available API “SM” or “SN” oils are not available, then the oil
change service interval is 3,000 mile (4,800 km).Scheduled Maintenance
