FORD 2015 E-450 - Manual (Page 102)

Use of any fuel other than recommended fuel can cause powertrain
damage, impair the emission control system or cause loss of vehicle
performance. Any damage to a vehicle that is caused by use of fuel not
recommended will not be covered under warranty.
Choosing the Right Fuel (Gasoline Engines)
Use only UNLEADED gasoline or UNLEADED gasoline blended with a
maximum of 15% ethanol in your gasoline vehicle. If your vehicle is a
Flex Fuel Vehicle (FFV), it will have a yellow fuel filler cap placed over
the fuel fill inlet.
Do not use:
• Fuels containing more than 15% ethanol or E-85 fuel.
• Fuels containing methanol.
• Fuels containing metallic based additives, including manganese-based
compounds.
• Fuels containing the octane booster additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded-fuel (The use of leaded fuel is prohibited by law).
Note: Use of any fuel other than recommended fuel can cause
powertrain damage, impair the emission control system or cause loss of
vehicle performance. Any damage to vehicle that is caused by use of fuel
not recommended will not be covered under warranty.
Octane Recommendations
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as “Regular” with
an octane rating below 87,
particularly in high altitude areas. Fuels with octane levels below 87 are
not recommended.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
