octane Ram 2500 2014 Owner's Manual

FUEL REQUIREMENTS
3.6L/6.4L Engine
These engines are designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high quality unleaded “regular”
gasoline having an octane rating of 87. The
use of premium gasoline is not recommended, as it will
not provide any benefit over regular gasoline in these
engines.
5.7L Engines
This engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having an octane range of 87 to 89. The manufacturer recom-
mends the use of 89 octane for optimum performance.
The use of premium gasoline is not recommended, as it
will not provide any benefit over regular gasoline in
these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturer’s world wide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications, if they are available.
568 STARTING AND OPERATING

E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing 10% ethanol (E10). Gasoline with higher
ethanol content may void the New Vehicle Limited
Warranty.
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,
570 STARTING AND OPERATING

CAUTION!(Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

572 STARTING AND OPERATING

Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel ethanol and
15% unleaded gasoline.
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 add less than 5 gallons (19 Liters) when
refueling

Engine Oil – 5.7L Engine For
2500/3500 trucks operating un-
der a gross combined weight rat-
inggreater than
14,000 lbs/(6,350 kg.)We recommend you use API Certified SAE 5W-30 Engine Oil, meeting the
requirements of Chrysler Material Standard MS-6395 such as MOPAR®, Penn-
zoil®, Shell Helix® or equivalent. Refer to your engine oil filler cap for correct
SAE grade.
Engine Oil – 6.4L For best performance and maximum protection under all types of operating
conditions, the manufacturer only recommends full synthetic engine oils that
meet the American Petroleum Institute (API) categories of SN. The manufacturer
recommends the use of Pennzoil Ultra™ 0W-40 or equivalent MOPAR® engine
oil meeting the requirements of Chrysler Material Standard MS-12633 for use in
all operating temperatures.
Engine Oil Filter We recommend you use MOPAR® brand Engine Oil Filters.
