2015 Ram 5500 Chassis Cab octane

General Information
This device complies with Part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions:
•This device may not cause harmful interference.
• This device must accept any interference received,
including interference that may cause undesired op-
eration.
The TPM sensors are regulated under one of the follow-
ing licenses:
United States GQ4-61T
Canada 1470A-42T
FUEL REQUIREMENTS
5.7L/6.4L 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 manufac-
turer recommends the use of 89 octane for optimum
performance. The use of premium gasoline (Over 89
octane) 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

Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% Ethanol
are not the responsibility of the manufacturer and may
not be covered under New Vehicle Limited Warranty.
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
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
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

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.

ComponentFluid, Lubricant, or Genuine Part
Engine Oil – 6.4L Engine 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 Penn-
zoil Ultra™ 0W-40 or equivalent MOPAR® engine oil
meeting the requirements of Chrysler Material Stan-
dard MS-12633 for use in all operating temperatures.
Engine Oil Filter – 5.7L/6.4L Engine We recommend you use MOPAR® Engine Oil Filters.
Spark Plugs – 5.7L/6.4L Engine We recommend you use MOPAR® Spark Plugs.
Fuel Selection – 5.7L/6.4L Engine 87 Octane Acceptable - 89 Octane Recommended.
