2017 FORD F250 SUPER DUTY fuel

Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
Filling the Fuel Tank
For consistent results when refueling:
•Turn the ignition off before fueling; aninaccurate reading results if the engineis left running.
•Use the same fill rate(low-medium-high) each time the tankis filled.
•Allow no more than one automaticshut-off when refueling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1,000 mi (1,600 km) of driving (this isyour engine’s break-in period). A moreaccurate measurement is obtained after2,000 mi (3,200 km) to 3,000 mi(4,800 km). Also, fuel expense, frequencyof fill ups or fuel gauge readings are notaccurate ways to measure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2. Each time you fill the fuel tank, recordthe amount of fuel added.
3. After at least three fill ups, fill the fueltank and record the current odometerreading.
4. Subtract your initial odometer readingfrom the current odometer reading.
To calculate L/100 km (liters per 100kilometers) fuel consumption, multiply theliters used by 100, then divide by kilometerstraveled. To calculate MPG (miles pergallon) fuel consumption, divide milestraveled by gallons used.
Keep a record for at least one month andrecord the type of driving (city or highway).This provides an accurate estimate of yourvehicle's fuel economy under currentdriving conditions. Keeping records duringsummer and winter will show howtemperature impacts fuel economy.
Conditions
•Heavily loading your vehicle reducesfuel economy.
•Carrying unnecessary weight in yourvehicle may reduce fuel economy.
•Adding certain accessories to yourvehicle such as bug deflectors, rollbarsor light bars, running boards and skiracks may reduce fuel economy.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures.
•Fuel economy may decrease whendriving short distances.
•You will get better fuel economy whendriving on flat terrain than when drivingon hilly terrain.

Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while yourvehicle is moving, especially at highspeeds.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for serviceof components affecting emission control,such non-Ford parts should be equivalentto genuine Ford Motor Company parts inperformance and durability.
Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehiclesare not permitted to intentionally remove
an emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement.
Please consult your warranty informationfor complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.
2. Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 192).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctions

present, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the on
position for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
1. 15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2. Allow your vehicle to sit for at leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.

EMISSION CONTROL SYSTEM
- DIESEL
Oxidation Catalytic Converter andDiesel Particulate Filter System (If
Equipped)
WARNING
The normal operating temperatureof the exhaust system is very high.Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the diesel oxidationcatalytic converter or the diesel particulatefilter. The diesel oxidation catalyticconverter and the diesel particulate filterheat up to very high temperatures afteronly a short period of engine operation andremain hot after you switch the engine off.
Your vehicle has a diesel particulate filter.The diesel particulate filter is an inline filterin the exhaust system that reduces carbonemissions by trapping exhaust particlesbefore they reach the tailpipe. The dieselparticulate filter looks similar to atraditional exhaust catalyst and is part ofthe exhaust system under your vehicle. Thefilter couples to a diesel oxidation catalystthat reduces the amount of harmfulexhaust emitted from the tailpipe. As sootgathers in the system, it begins to restrictthe filter. The system must periodicallyclean the soot that gathers inside the filter.This is carried out in two ways, passiveregeneration and active regeneration. Bothmethods occur automatically and requireno actions from the driver. During eitherone of these regeneration methods,although you may notice a change inexhaust tone. At certain times, theinformation display shows variousmessages related to the diesel particulatefilter. See Information Messages (page128).
Diesel Particulate Filter Maintenance
You must properly maintain your vehicle'sdiesel particulate filter in order for it tofunction properly.
Do not disregard maintenance messagesthat appear in the information display.Failure to follow the instructions of aninformation message may degrade vehicleperformance and could lead to enginedamage that may not be covered by thevehicle Warranty.
Failure to perform active or operatorcommanded regeneration when instructedcould result in a clogged diesel particulatefilter. If the diesel particulate filter fillsbeyond the regeneration threshold, yourvehicle disables the ability for active andoperator commanded regeneration. Thiscould result in irreversible damage to thediesel particulate filter requiringreplacement that may not be covered bythe vehicle Warranty.
Passive Regeneration
In passive regeneration, the exhaustsystem temperature and constituentsautomatically clean the filter by oxidizingthe soot. Cleaning automatically occursduring normal vehicle operating conditionsdue to driving patterns.
Active Regeneration
Once the diesel particulate filter is full ofexhaust particles, the engine controlmodule commands the exhaust system toclean the filter through active regeneration.Active regeneration requires the enginecomputer to raise the exhaust temperatureto eliminate the particles. During cleaning,the particles convert to harmless gasses.Once cleaned the diesel particulate filtercontinues trapping exhaust particles.

The regeneration process operates moreefficiently when you drive your vehicle ata constant speed above 30 mph(48 km/h) and at a steady engine speedfor approximately 20 minutes. Thefrequency and duration of regenerationfluctuates by how you drive your vehicle,outside air temperature and altitude. Formost driving, regeneration frequency variesfrom 100–500 mi (160–805 km) betweenoccurrences and each occurrence lasts9–35 minutes. You can usually reduce theduration of regeneration if you maintain aconstant speed above 30 mph (48 km/h).
When the engine control module detectsthat the diesel particulate filter is nearlyfull of particulates and you are notoperating your vehicle in a manner to alloweffective automatic regeneration,messages appear in the informationdisplay as a reminder for you to drive yourvehicle in order to clean the dieselparticulate filter. If you drive your vehiclein a manner to allow effective automaticregeneration, the information displayshows a cleaning exhaust filter message,which is the normal regeneration process.You can also choose operator commandedregeneration to clean the exhaust systemat this point. See Information Messages(page 128).
If you are not able to drive in a manner thatallows effective automatic activeregeneration or you choose to performregeneration of the diesel particulate filterwhile at idle, then operator commandedregeneration would need to be performed.
Operator Commanded Regeneration(If Equipped)
If your vehicle is operated with significantstationary operation, low speed drivecycles less than 25 mph (40 km/h), shortdrive cycles, a drive time is less than 10 -15 minutes or the vehicle does not fullywarm up, passive and active regenerationmay not sufficiently clean the diesel
particulate filter system. Operatorcommanded regeneration allows you tomanually start regeneration of the dieselparticulate filter at idle to clean the filter.If you are not sure whether your vehicle hasthis feature, contact an authorized dealer.
When to Carry Out Operator CommandedRegeneration
You can use the operator commandedregeneration feature when a messageappears in the information display and youare not able to drive in a manner thatallows effective automatic activeregeneration or if you choose to manuallystart the regeneration of the dieselparticulate filter manually while the vehicleis idle. See Information Messages (page128).
Operator Commanded RegenerationPrecautions and Safe Exhaust Position
WARNING
Failure to comply with the followinginstructions for OperatorCommanded Regeneration mayresult in fire, serious injury, death orproperty damage.
Make sure that the louvers located at thetip of the exhaust are clear of anyobstructions as they are used to introducefresh air into the tailpipe to cool theexhaust gases as they leave the exhaustsystem.
Before you start operator commandedregeneration, do the following:
•Shift into park (P) and apply theparking brake on stable, level ground.
•Park your vehicle outside of anystructure.

•Park your vehicle 10–15 ft (3–5 m)away from any obstructions and awayfrom materials that can easily combustor melt, for example paper, leaves,petroleum products, fuels, plastics andother dry organic material.
•Make sure there is a minimum of 1/8tank of fuel.
•Make sure all fluids are at proper levels.
How to Start Operator CommandedRegeneration
WARNING
Stay clear of the exhaust tailpipeduring regeneration. Hot exhaustgases can burn you badly.
Note:You cannot use the operatorcommanded regeneration until the dieselparticulate filter load percentage hasreached 100%. The diesel particulate filterload percentage fluctuates up and downwhen driving your vehicle due to active andpassive regenerations.
Note:During the use of operatorcommanded regeneration, you may observea light amount of white smoke. This isnormal.
You may not be able to useoperator commandedregeneration if the service enginesoon warning lamp appears in theinformation display
Information Display Procedure
Start with your vehicle engine and when ithas reached the normal operatingtemperature, press the information displaycontrol button on the steering wheel. SeeGeneral Information (page 111). If amessage advising that the exhaust filter isfull appears in the information display,press the OK button to set the display toY. Answer yes to this prompt and then
follow the next prompts regarding exhaustposition required to initiate operatorcommanded regeneration. Be sure tounderstand each prompt. If you are notsure what is being asked by each prompt,contact an authorized dealer. The displayconfirms the operation has started andwhen it has finished.
If the diesel particulate filter is near or atsaturation, a message requestingpermission to initiate filter cleaningappears in the information display. SeeInformation Messages (page 128).Answer yes to this prompt and then followthe next prompts regarding exhaustposition required to initiate operatorcommanded regeneration. Be sure tounderstand each prompt. If you are notsure what is being asked by each prompt,contact an authorized dealer. The displayconfirms the operation has started andwhen it has finished. You can also drive toclean the filter.
When the system is at the pointof oversaturation, the serviceengine warning lamp illuminatesand a message appears in the informationdisplay. You cannot initiate filter cleaning.You must have your vehicle checked assoon as possible.
Once operator commanded regenerationstarts, engine speed increases toapproximately 2000–2500 rpm and thecooling fan speed increases. You will heara change in audible sound due to enginespeed and cooling fan speed increases.
It is not necessary to open the hood on theengine compartment. Once operatorcommanded regeneration completes, theengine speed returns to normal idling. Theexhaust system remains very hot forseveral minutes even after regeneration iscomplete. Do not reposition the vehicleover materials that could burn until the

exhaust system has had sufficient time tocool. Depending on the amount of sootcollected by the diesel particulate filter,ambient temperature and altitude,operator commanded regeneration lastsapproximately 30 minutes.
Operator Commanded Regenerationwith Automatic Regeneration Control(If Equipped)
If your vehicle is operated with significantstationary operation, low speed drivecycles less than 25 mph (40 km/h), shortdrive cycles, drive time less than 15 minutesor the vehicle does not fully warm up,passive and active regeneration may notsufficiently clean the diesel particulatefilter system. You can switch off automaticregeneration until better driving conditionsare available, for example steady highspeed driving. You can then switchautomatic regeneration back on to cleanthe diesel particulate filter.
Switching Automatic RegenerationControl On and Off
To switch operator commandedregeneration on and off, use theinformation display control on the steeringwheel. See General Information (page111). Scroll to the exhaust cleaningmessage and then select Y or N to switchit On or Off.
How to Interrupt or Cancel OperatorCommanded Regeneration
If you need to cancel the operatorcommanded regeneration, pressing thebrake, accelerator or switching the engineoff stops the procedure. Depending on theamount of time you allowed the operatorcommanded regeneration to operate, sootmay not have had sufficient time to be fullyeliminated, but the exhaust system andexhaust gas may still be hot. If you shut
your vehicle off during operatorcommanded regeneration, you may noticeturbo flutter. This is a normal consequencecaused by shutting off a diesel engineduring boosted operation and is considerednormal.
Filter Service and Maintenance
Over time, a slight amount of ash buildsup in the diesel particulate filter, which isnot removed during the regenerationprocess. The filter may need to be removedfor ash cleaning at approximately120,000 mi (190,000 km) or it may needto be replaced with a new orremanufactured part. Actual mileagevaries depending on engine and vehicleoperating conditions. The filter may needto be replaced with a new orremanufactured part at approximately250,000 mi (400,000 km). Actualmileage varies depending on engine andvehicle operating conditions.
If filter service is required, theengine control system warninglamp illuminates in theinformation display.
If there are any issues with thediesel particulate filter system,the engine control systemwarning lamp and a serviceengine soon warning lampilluminate to inform you thatyour vehicle requires service. Have yourvehicle checked as soon as possible.
