It is best not to alternate repeatedlybetween gasoline and E85. If you do switchfuels, it is recommended that you add asmuch fuel as possible—at least half a tank.Do not add less than 5.0 gal (18.9 L) whenrefueling. You should drive the vehicleimmediately after refueling for at least 5 mi(8 km) to allow the vehicle to adapt to thechange in ethanol concentration. Therecommendation if you exclusively use E85fuel, is to fill the fuel tank with regularunleaded gasoline at each scheduled oilchange.
Octane Recommendations

Super Duty (TFA) Canada/United States of America, enUSA, First Printing
Fuel and RefuelingE161513

We recommend regular unleaded gasolinewith a pump (R+M)/2 octane rating of 87.Some stations offer fuels posted as regularwith an octane rating below 87, particularlyin high altitude areas. We do notrecommend fuels with an octane ratingbelow 87.
Do not be concerned if your enginesometimes knocks lightly. However, if itknocks heavily under most drivingconditions while you are using fuel with therecommended octane rating, see yourauthorized dealer to prevent any enginedamage.
RUNNING OUT OF FUEL
Avoid running out of fuel because thissituation may have an adverse effect onengine components.
If you have run out of fuel:
•You may need to cycle the ignition fromoff to on several times after refuelingto allow the fuel system to pump thefuel from the tank to the engine. Onrestarting, cranking time will take a fewseconds longer than normal. Withkeyless ignition, just start the engine.Crank time will be longer than usual.
•Normally, adding 1.06 gal (4 L) of fuelis enough to restart the engine. If thevehicle is out of fuel and on a steepgrade, more than 1.06 gal (4 L) may berequired.
REFUELING
WARNINGS

Stop refueling after the fuel pumpnozzle automatically shuts off for thesecond time. Failure to follow thiswill fill the expansion space in the fuel tankand could lead to fuel overflowing.
Do not remove the fuel pump nozzlefrom its fully inserted position whenrefueling.
Use the following guidelines to avoidelectrostatic charge build-up when fillingan ungrounded fuel container:
•Place approved fuel container on theground.
