open gas tank Ram 2500 2013 Owner's Manual

If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
• OBD II “Malfunction Indicator Light” on
• poor engine performance
• poor cold start and cold drivability
• increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
• drain the fuel tank (see your authorized dealer)
• change the engine oil and oil filter
• disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.MMT In Gasoline
MMT (Methylcyclopentadienyl Manganese Tricarbonyl)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
528 STARTING AND OPERATING

WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit in or near the vehicle when remov-
ing the fuel filler tube cap (gas cap) or filling the
tank. Do not use E-85 as a cleaning agent and never
use it near an open flame.
Fuel Requirements
Your vehicle will operate on both unleaded gasoline with
an octane rating of 87, or E-85 fuel, or any mixture of
these two. For best results, a refueling pattern that
alternates between E-85 and unleaded gasoline should be
avoided.
When you do switch fuel types it is recommended that:
•you do not switch when the fuel gauge indicates less
than 1/4 full •
you do not add less than 5 gallons (19 Liters) when
refueling
• you operate the vehicle immediately after refueling for
a period of at least 5 minutes
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.
NOTE:
• When the ambient temperature is above 90° F (32° C),
you may experience hard starting and rough idle
following start up even if the above recommendations
are followed.
• Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
