Cold Weather Starting
WARNINGS
Do not use starting fluid, for exampleether, in the air intake system. Suchfluid could cause immediateexplosive damage to the engine andpossible personal injury.
Do not add gasoline, gasohol, alcoholor kerosene to diesel fuel. Thiscreates a serious fire hazard andcauses engine performance problems.
We recommend that the engine blockheater be used for starting when thetemperature is -9°F (-23°C) or colder. SeeEngine Block Heater (page 181).
When operating in cold weather, you mayuse Motorcraft® cetane improvers ornon-alcohol-based cetane improvers froma reputable manufacturer as needed.
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine does not start, switch theignition off and wait 30 seconds beforetrying again.
Switch the ignition on. Do notstart the engine until theglow-plug indicator turns off.
When the glow plug pre-heat indicatorturns off, turn the key to start. After youstart the engine, the glow plugs mayremain on for a period. If you do not startthe engine before the glow plug activationtime ends, you will need to reset the glowplugs by switching the ignition off. Afterthe engine starts, allow it to idle for about15 seconds. This protects the engine. Donot increase engine speed until the oilpressure gauge indicates normal pressure.
Cold Weather Operation
Note:Idling in cold weather does not heatthe engine to its normal operatingtemperature. Long periods of idling,especially in cold weather, can cause abuildup of deposits which can cause enginedamage.
Change to a lighter grade engine oil tomake starting easier under theseconditions. Refer to engine oilspecifications. See Capacities andSpecifications (page 427).
Diesel fuel is adjusted seasonally for coldtemperatures. Diesel fuel which has notbeen properly formulated for the ambientconditions may gel which can clog the fuelfilters. One indication that the fuel filter(s)may be clogged is if the engine starts, stallsafter a short time, and then does notrestart. If you have been using biodiesel,you may need to use a fuel with lowerbiodiesel content, try another brand, ordiscontinue using biodiesel. Do not usealcohol based additives to correct fuelgelling. This may result in damage to thefuel injectors and system. Use the properanti-gel and performance improvementproduct. See Capacities andSpecifications (page 427).

Starting and Stopping the Engine

Your vehicle has a fuel and water separatorthat recirculates fuel from the engine tohelp prevent fuel filter clogging. To avoidengine fuel starvation during cold weatheroperation of 32°F (0°C) or below, werecommend that the fuel level in your tankshould not drop below ¼ full. This helpsprevent air from entering the fuel systemand stalling the engine.
Your vehicle has a selective catalyticreduction system that uses Diesel ExhaustFluid (DEF) to operate properly. You needto replenish your vehicle’s DEF at certainintervals. When filling your vehicle’s DEFtank in cold weather, take special care toprevent damage to the tank. SeeSelective Catalytic Reduction System(page 188).
In cold weather below 32°F (0°C), theengine may slowly increase to a higher idlespeed if you leave it idling in park (P). Asthe engine warms-up, the engine soundlevel decreases due to the activation ofPCM-controlled sound reduction features.
If you operate your vehicle in a heavysnowstorm or blowing snow conditions,snow and ice can clog the engine airinduction. If this occurs, the engine mayexperience a significant reduction in poweroutput. At the earliest opportunity, clearall the snow and ice away from inside theair filter assembly. Remove the air cleanercover and the air filter and remove anysnow or ice. Remove any debris, snow orice, on the foam filter by brushing thesurface with a soft brush. Once you havecleared all of the debris, reinstall the airfilter and cover.
Do not use water, solvents, or a hard brushfor cleaning the foam filter.
WARNING
To reduce the risk of vehicle damageand personal burn injuries, do notstart your engine with the air cleanerremoved and do not remove it while theengine is running.
In order to operate the engine intemperatures of 32°F (0°C) or lower, readthe following instructions:
•Make sure that the batteries are ofsufficient size and are fully charged.Check other electrical components tomake sure they are in optimumcondition.
•Use the proper coolant solution at theconcentration recommendedprotecting the engine against damagefrom freezing.
•Try to keep the fuel tank full as muchas possible at the end of operation toprevent condensation in the fuelsystem.
•Make sure you use proper cold weatherengine oil and that it is at its properlevel. Also, if necessary, make sure tofollow the engine oil and filter changeschedule found under the Specialoperating conditions section listed inthe scheduled maintenanceinformation.
•At temperatures of -9°F (-23°C) orbelow, it is recommended that you usean engine block heater to improve coldengine starting.
•If operating in arctic temperatures of-20°F (-29°C) or lower, consult yourtruck dealer for information aboutspecial cold weather equipment andprecautions.

Operation in Standing Water
Ingestion of water into the diesel enginecan result in immediate and severedamage to the engine. If driving throughwater, slow down to avoid splashing waterinto the intake. If the engine stalls, and yoususpect ingestion of water into the engine,do not try to restart the engine. Consultyour dealer for service immediately.
Your fuel tank vents to the atmosphere byvalves on top of the tank and through thefuel cap. If water reaches the top of thetank, the valves may pull water into thefuel tank. Water in the fuel can causeperformance issues and damage the fuelinjection system.
DIESEL PARTICULATE FILTER
The filter forms part of the emissionsreduction system on your vehicle. It filtersharmful diesel particulates (soot) from theexhaust gas.
Regeneration
WARNING
Do not park or idle your vehicle overdry leaves, dry grass or othercombustible materials. Theregeneration process creates very highexhaust gas temperatures and the exhaustwill radiate a considerable amount of heatduring and after regeneration and after youhave switched the engine off. This is apotential fire hazard.
Note:Avoid running out of fuel.
Note:During regeneration at low speed orengine idle, you may smell a hot metallicodor and could notice a clicking metallicsound. This is due to the high temperaturesreached during regeneration and is normal.
Note:Changes in the engine or exhaustsound may be heard during the regenerationprocess.
The diesel particulate filter on your vehiclerequires periodic regeneration to maintainits correct function. Your vehicle will carryout this process automatically.
If your journeys meet one of the followingconditions:
•You drive only short distances.
•You frequently switch the ignition onand off.
•Your journeys contain a high level ofacceleration and deceleration.
You must carry out occasional trips withthe following conditions to assist theregeneration process:
•Drive your vehicle in more favorableconditions, which you will find at highervehicle speeds in normal driving, on amain road or freeway for a minimumof 20 minutes. This drive may includeshort stops that will not affect theregeneration process.
•Avoid prolonged idling and alwaysobserve speed limits and roadconditions.
•Do not switch the ignition off.
•Select a suitable gear to ideallymaintain engine speed between 1500and 3000 RPM.

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel sprayand fire.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler inlet, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Automotive fuels can cause seriousinjury or death if misused ormishandled.
Flow of fuel through a fuel pumpnozzle can produce static electricity.This can cause a fire if you are fillingan ungrounded fuel container.
Fuel may contain benzene, which isa cancer-causing agent.
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Observe the following guidelines whenhandling automotive fuel:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Always turn off the vehicle beforerefueling.
•Automotive fuels can be harmful orfatal if swallowed. Fuel such asgasoline is highly toxic and ifswallowed can cause death orpermanent injury. If fuel is swallowed,call a physician immediately, even if nosymptoms are immediately apparent.The toxic effects of fuel may not bevisible for hours.
•Avoid inhaling fuel vapors. Inhaling toomuch fuel vapor of any kind can leadto eye and respiratory tract irritation.In severe cases, excessive or prolongedbreathing of fuel vapor can causeserious illness and permanent injury.
•Avoid getting fuel liquid in your eyes. Iffuel is splashed in the eyes, removecontact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek propermedical attention could lead topermanent injury.
•Fuels can also be harmful if absorbedthrough the skin. If fuel is splashed onthe skin, clothing or both, promptlyremove contaminated clothing andwash skin thoroughly with soap andwater. Repeated or prolonged skincontact with fuel liquid or vapor causesskin irritation.
•Be particularly careful if you are takingAntabuse or other forms of Disulfiramfor the treatment of alcoholism.Breathing gasoline vapors could causean adverse reaction, serious personalinjury or sickness. If fuel is splashed onthe skin, wash the affected areasimmediately with plenty of soap andwater. Consult a physician immediatelyif you experience any adverse reactions.

FUEL QUALITY - E85
Choosing the Right Fuel - Flex FuelVehicles
Flex fuel vehicles have one of the followingidentifiers:
•Yellow fuel filler cap.
•Yellow bezel around the fuel filler inlet.
•Yellow fuel filler housing.
•Yellow E85 label on the fuel tank fillerdoor.
Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87 orregular unleaded gasoline blended with amaximum of 85% ethanol (E85).
Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. We do not recommendthese fuels.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as wellas other conditions, for example whentowing a trailer. See Towing (page 268).
Do not use any fuel other than thoserecommended because they could lead toengine damage that will not be covered bythe vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuels containing more than 85%ethanol or E100 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.

Switching Between E85 andGasoline
We do not recommend repeatedlyalternating between E85 and gasoline. Ifyou switch from using E85 to gasoline, orfrom gasoline to E85, add as much fuel aspossible, at least half a tank. Drive yourvehicle immediately for a minimum of 5 mi(8 km) to allow it to adapt to the changein ethanol concentration. If you use E85exclusively, we recommend that you fillthe fuel tank with regular unleadedgasoline at each scheduled oil change.
FUEL QUALITY - DIESEL
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs Required (UnitedStates/Canada/Puerto Rico/U.S.Virgin Islands And Other Locales)
You should use Ultra-Low Sulfur Dieselfuel (also known as ULSD) designated asnumber 1-D or 2-D with a maximum of15-ppm sulfur in your diesel vehicle. Youmay operate your vehicle on diesel fuelscontaining up to 20% biodiesel, alsoknown as B20. These fuels should meetthe ASTM D975 diesel or the ASTM D7467B6-B20 biodiesel industry specifications.Outside of North America, use fuelsmeeting EN590 or equivalent local marketstandard.
Note:The vehicle Warranty does not coverdamage caused by using an improper typeof fuel or fuel additive.
Note:Do not blend used engine oil withdiesel fuel under any circumstances.Blending used oil with the fuel willsignificantly increase your vehicle’s exhaustemissions and reduce engine life due toincreased internal wear.
Using low sulfur diesel fuel(16-500 ppm) or high sulfurdiesel fuel (greater than 500ppm) in your diesel engine will causecertain emission components tomalfunction which may also cause theservice engine soon light to illuminateindicating an emissions-related concern.
Diesel fuel is adjusted seasonally for coldtemperature. For best results attemperatures below 19°F (-7°C), it isrecommended to use a diesel fuel whichhas been seasonally adjusted for theambient conditions.
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs Not Required
For the engine to operate reliably onlow-sulfur or high-sulfur diesel fuel, theengine must be a factory built high-sulfurengine (available as a dealer order optionfor select markets) or an ultra low sulfurdiesel fuel configured engine that has beenretrofitted for high-sulfur diesel fuel usingFord Motor Company dealer service parts.Failure to use retrofit components otherthan those available through yourauthorized dealer will result in coolantsystem damage, engine overheating,selective catalyst reduction system ordiesel particulate filter damage andpossible base engine damage.
Use only a diesel engine configured for usewith high sulfur diesel fuel in markets withdiesel fuel that has sulfur content greaterthan 15 ppm. Using low sulfur diesel fuel(16–500 ppm) or high sulfur diesel fuel(greater than 500 ppm) in a diesel enginedesigned to use only Ultra Low SulfurDiesel fuel may result in damage to engineemission control devices and theaftertreatment system, potentiallyrendering the vehicle inoperable.

Vehicles with engines configured for usewith high sulfur diesel fuel are onlyavailable for sale in countries where ultralow sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in a ultra low sulfurdiesel fuel market that are subsequentlyexported to non- ultra low sulfur diesel fuelmarkets will need to be retrofitted (at thecustomer’s expense using Ford authorizeddealer service parts) in order to be reliablyoperated on non- ultra low sulfur dieselfuel.
Biodiesel
WARNINGS
Do not use home heating oil,agricultural fuel, raw fats and oils,waste cooking greases, biodieselfuels greater than 20% or any diesel fuelnot intended for highway use. Damage tothe fuel injection system, engine andexhaust catalyst can occur if an improperfuel is used. Do not add gasoline, gasoholor alcohol to diesel fuel. This practicecreates a serious fire hazard and engineperformance problems.
Do not mix diesel fuel with gasoline,gasohol or alcohol. This could causean explosion resulting in personalinjury.
Do not add gasoline, gasohol oralcohol to diesel fuel. This practicecreates a serious fire hazard resultingin personal injury and engine performanceproblems.
Do not use home heating oil or anydiesel fuel not intended for highwayuse. Damage to the fuel injectionsystem, engine, exhaust catalyst and dieselparticulate filter can occur if an improperfuel is used. Red dye is used to identifyfuels intended for agricultural andnon-highway use.
You may operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.
Biodiesel fuel is a chemically convertedproduct from renewable fuel sources, suchas vegetable oils, animal fats and wastecooking greases.
To help achieve acceptable engineperformance and durability when usingbiodiesel in your vehicle:
•Confirm the biodiesel content of thefuel to be B20 (20% biodiesel) or less
•Only use biodiesel fuel of good qualitythat complies with industry standards
•Follow the recommended servicemaintenance intervals. SeeScheduled Maintenance (page 573).
•Do not store biodiesel fuel in the fueltank for more than 1 month
•Consider changing brands or reducingbiodiesel content if you have coldtemperature fuel gelling issues or afrequent LOW FUEL PRESSUREmessage appearing
•Do NOT use raw oils, fats or wastecooking greases
Use of biodiesel in concentrations greaterthan 20% may cause damage to yourvehicle, including engine and/or exhaustafter-treatment hardware (exhaustcatalyst and particulate filter) failures.Concentrations greater than 20% can alsocause fuel filter restrictions that may resultin a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil isrecommended for fuels with greater than5% biodiesel (B5). Refer to the Specialoperating conditions section under theSchedule Maintenance chapter for moreinformation about oil change intervals andother maintenance when operating onbiodiesel.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201710, Second Printing
Fuel and Refueling

Look for a label on the fuel pump toconfirm the amount of biodiesel containedin a diesel fuel. Biodiesel content is oftenindicated with the letter B followed by thepercent of biodiesel in the fuel. Forexample, B20 indicates a fuel containing20% biodiesel. Ask the service stationattendant to confirm the biodiesel contentof a diesel fuel if you do not see a label onthe fuel pump.
Biodiesel fuels degrade more easily thandiesel fuels not containing biodiesel andshould not be stored in the fuel tank formore than 1 month. If you plan to park orstore your vehicle for more than 1 month,then you should empty your vehicle fueltank of biodiesel fuel. You should fill thetank with a pure petroleum-based dieselfuel and run your vehicle for a minimum of30 minutes.
Note:Degraded or oxidized biodiesel candamage fuel system seals and plastics andcorrode steel parts.
During cold weather, if you have problemsoperating on biodiesel, you may need touse a diesel fuel with lower biodieselcontent, try another brand, or discontinuethe use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add anyaftermarket additives to your fuel if youuse a high quality diesel fuel that conformsto ASTM industry specifications.Aftermarket additives can damage the fuelinjector system or engine.
Use Motorcraft® cetane booster or anequivalent cetane booster additive if yoususpect fuel has low cetane. UseMotorcraft® anti-gel & performanceimprover or an equivalent additive if thereis fuel gelling.
Do not use alcohol-based additives toimprove cetane quality, to prevent fuelgelling or any other use. The use of alcoholadditives may result in damage to the fuelinjectors and system. See Capacities andSpecifications (page 427).
The Vehicle Warranty may not coverrepairs needed to correct the effects ofusing an aftermarket product that doesnot meet Ford specifications in your fuel.
FUEL QUALITY - GASOLINE
Choosing the Right Fuel
We recommend regular unleaded gasolinewith a minimum pump (R+M)/2 octanerating of 87. Some fuel stations offer fuelsposted as regular unleaded gasoline withan octane rating below 87, particularly inhigh altitude areas. We do not recommendfuels with an octane rating below 87.
Do not use any fuel other than thoserecommended because they could lead toengine damage that may not be coveredby the vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
