2024 FORD F650/750 Owners Manual

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
WARNING: Do not mix diesel withgasoline, gasohol or alcohol. This couldcause an explosion.
Note:Do not use home heating oil,agricultural fuel, raw fats and oils, wastecooking greases, biodiesel fuels greater than20% or any diesel fuel not intended forhighway use. Red dye is used to identifyfuels intended for agricultural andnon-highway use. Damage to the fuelinjection system, engine and exhaustcatalyst can occur if an improper fuel isused.
You may operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.

2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and RefuelingE67028

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 325).
•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.
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.
110
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

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.
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
Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. The use of these fuelscould result in engine damage that will notbe covered by the vehicle warranty.
We do not recommend these fuels. Forbest 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 a Trailer(page 181).
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.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance. Foradditional information, refer towww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 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.

RUNNING OUT OF FUEL -
DIESEL
Avoid running out of fuel. This allows air toenter the fuel system and may make itdifficult to restart your vehicle.
If your vehicle runs out of fuel:
•Normally adding 4–5 gal (15–19 L) offuel is enough to restart the engine. Ifyour vehicle is out of fuel and on asteep grade, more than 5 gal (19 L)may be required.
•You must purge trapped air from thesystem before restarting the engine.
Purging Air From the System
Switch the ignition on for 30 seconds andthen switch the ignition off. Repeat thisoperation six times in a row to purge anytrapped air from the fuel system.
Any remaining air in the system self-purgeswhen the engine starts. The engine mayrun rough or produce white smoke whenair remains in the fuel system. This isnormal and stops after a short period. Ifthe engine continues to run rough, haveyour vehicle checked as soon as possible.
Starting the Engine
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine fails to start, switch the ignitionoff and wait 30 seconds before crankingthe engine again. See Starting a DieselEngine (page 103).
RUNNING OUT OF FUEL -
GASOLINE
Avoid running out of fuel because thissituation may have an adverse effect onpowertrain components.
If you run out of fuel:
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal. With keyless ignition, just startthe engine. Crank time will be longerthan usual.
•Normally, adding 1 gal (3.8 L) of fuel isenough to restart the engine. If thevehicle is out of fuel and on a steepgrade, more than 1 gal (3.8 L) may berequired.
•The service engine soon indicator maycome on. See Warning Lamps andIndicators (page 67).
REFUELING - DIESEL
WARNING: Fuel vapor burnsviolently and a fuel fire can cause severeinjuries.
WARNING: Read and follow all theinstructions on the pump island.
WARNING: When refueling alwaysshut the engine off and never allowsparks or open flames near the fuel tankfiller valve. Never smoke or use a cellphone while refueling. Fuel vapor isextremely hazardous under certainconditions. Avoid inhaling excess fumes.
WARNING: Stay outside yourvehicle and do not leave the fuel pumpunattended when refueling your vehicle.
WARNING: Keep children awayfrom the fuel pump. Never let childrenpump fuel.
112
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

WARNING: Wait at least fiveseconds before removing the fuel pumpnozzle to allow any residual fuel to draininto the fuel tank.
WARNING: Stop refueling after thefuel pump nozzle automatically shutsoff for the second time. Failure to followthis will fill the expansion space in thefuel tank and could lead to fueloverflowing.
WARNING: Do not remove the fuelpump nozzle from its fully insertedposition when refueling.
An engine that suddenly becomes noisy oroperates poorly after a fuel fill could beusing substandard fuel. We recommendthat you purchase diesel fuel from areputable fuel station.
Use only clean, approved containers thatprevent the entry of dirt or water wheneveryou store diesel fuel.
Do not store diesel fuel in a galvanizedcontainer. The fuel dissolves the zinc in thegalvanized container. The zinc will thenremain in the fuel. If you run thecontaminated fuel through the engine, thezinc damages the fuel injectors. Enginedamage caused may not be covered bythe vehicle warranty.
Use the following guidelines to avoidelectrostatic charge build-up when fillingan ungrounded fuel container:
•Place the approved fuel container onthe ground.
•Do not fill a fuel container while it is inthe vehicle (including the cargo area).
•Keep the fuel pump nozzle in contactwith the fuel container when filling.
•Do not use a device that would holdthe fuel pump handle in the fill position.
Fuel Filler Cap
WARNING: The fuel system maybe under pressure. If you hear a hissingsound near the fuel filler inlet, do notrefuel until the sound stops. Otherwise,fuel may spray out, which could causeserious personal injury.
Note:If you do not use the correct fuel fillercap, excessive pressure or vacuum in thefuel tank may damage the fuel system orcause the fuel cap to disengage in a crash.
The fuel tank has a threaded fuel filler cap.
Note:If you must replace the fuel filler cap,replace it with a fuel filler cap that isdesigned for your vehicle. The vehiclewarranty may be void for any damage to thefuel tank or fuel system if the correctgenuine Ford, Motorcraft or other certifiedfuel filler cap is not used.
When refueling the vehicle fuel tank do thefollowing:
1.Bring your vehicle to a complete stopand shift into neutral (N) or park (P).
2.Apply the parking brake and switch theignition off.
3.Turn the fuel filler capcounterclockwise and remove it.
4.Refuel your vehicle as required.
5.Replace the fuel filler cap, turn itclockwise until you feel a strongresistance.
Fuel Fill Rate
Your vehicle has a fuel fill inlet that is ableto accept fuel up to 20 gal (75 L) perminute from a fuel-dispensing nozzle.Pumping fuel at greater flow rates mayresult in premature nozzle shut off or spitback.
113
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

Truck stops have fuel pumps and nozzlesdesigned for larger, heavy-duty trucks. Ifyou are refueling your vehicle at a truckstop and the nozzle shuts off repeatedly,wait 5-10 seconds, then use a slower fillrate.

When refueling the vehicle fuel tank do thefollowing.
114
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

1.When your vehicle has stopped, shiftinto neutral (N) or park (P).
2.Apply the parking brake and switch theignition off.
3.Turn the fuel filler capcounterclockwise and remove it.
4.Refuel your vehicle as required.
5.Replace the fuel filler cap, turn itclockwise until you feel a strongresistance.
If the fuel cap warning lamp or a warningmessage appears in the instrument cluster,you may not have installed the fuel fillercap correctly.
If the fuel cap warning lamp remains on,at the next opportunity, safely pull off ofthe road, remove the fuel filler cap, alignthe cap properly and reinstall it. The checkfuel cap warning lamp or warning messagemay not reset immediately. It may takeseveral driving cycles for the indicators toturn off. A driving cycle consists of anengine start-up (after four or more hourswith the engine off) followed by normalcity and highway driving.
FUEL CONSUMPTION
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included inthe advertised capacity is an emptyreserve. The empty reserve is anunspecified amount of fuel that remainsin the fuel tank when the fuel gaugeindicates empty.
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.
115
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

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.
FUEL TANK SELECTOR
SWITCH (IF EQUIPPED)
Your vehicle may have two fuel tanks. Thefuel in each fuel tank is independentlyused. Use the switch on the instrumentpanel to select the left-hand or right-handfuel tank. The fuel gauge indicates theremaining fuel in the selected fuel tank.See Gauges (page 64).
