2023 FORD F150 engine

SELECTING THE CORRECT FUEL -GASOLINE
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane 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.
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 a Trailer(page 418).
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.
For additional information, visitwww.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, which is amanganese-based fuel additive, will impairengine performance and affect theemission control system.
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.

2.Fully insert the fuel filler funnel into thefuel filler inlet.
3.Add fuel to your vehicle from the fuelcontainer.
4.Remove the fuel filler funnel.
5.Fully close the fuel filler door.
6.Clean the fuel filler funnel and place itback in your vehicle or correctly disposeof it.
Note:If your vehicle runs out of fuel add aminimum of 1.3 gal (5 L) of fuel to restartthe engine.
Note:You may need to switch the ignitionfrom off to on several times after refuelingto allow the fuel system to pump the fuelfrom the tank to the engine. Whenrestarting, cranking time takes a fewseconds longer than normal.
Note:Extra funnels can be purchased froman authorized dealer if you choose todispose of the funnel.

REFUELING YOUR VEHICLE -EXCLUDING: HYBRID ELECTRICVEHICLE (HEV)
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: Fuel vapor burnsviolently and a fuel fire can cause severeinjuries.
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.

WARNING: Do not remove the fuelpump nozzle from its fully insertedposition when refueling.
WARNING: Stop refueling whenthe fuel pump nozzle automaticallyshuts off for the first time. Failure tofollow this will fill the expansion spacein the fuel tank and could lead to fueloverflowing.
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: Wait at least fiveseconds before removing the fuel pumpnozzle to allow any residual fuel to draininto the fuel tank.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of yourvehicle's emissions system and filtersharmful pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
To avoid damaging the catalytic converter:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 481).
•Use the correct fuel. See Fuel andRefueling (page 251).
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Do not make any unauthorizedchanges to your vehicle or engine. By law,vehicle owners and anyone whomanufactures, repairs, or services a fleet ofvehicles are not permitted to intentionallyremove an emission control device orprevent it from working.
