2018 Ram 2500 oil type

Engine Oil Viscosity (SAE Grade) — 6.4L Engine
Use Mopar SAE 0W-40 engine oil approved to FCA Mate-
rial Standard MS-12633 such as Pennzoil Ultra equivalent
is recommended for all operating temperatures.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Compart-
ment” illustration in this section.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes are
followed.
Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact an authorized dealer, service station
or governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter at
every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type dispos-
able oil filter. Use a filter of this type for replacement. The
quality of replacement filters varies considerably. Only
high quality filters should be used to assure most efficient
service. Mopar engine oil filters are high quality oil filters
and are recommended.
530 SERVICING AND MAINTENANCE

NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials
1500 Model rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) Mopar Limited Slip
Additive be added to the gear lubricant. Refer to “Fluids
And Lubricants” in “Technical Specification” for further
information. The Mopar Limited Slip Additive should be
added to the gear lubricant whenever a fluid change is
made to an axle equipped with a Limited Slip Differential.
2500/3500 Model axles DO NOT REQUIREany limited
slip oil additive (friction modifiers).
NOTE: When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive), the Lim-
ited Slip Additive should be added before the gear lubri-
cant is added to insure proper additive fill.
Drain And Refill
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.
Transfer Case
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
Fluid Level Check
This fluid level can be checked by removing the filler plug.
The fluid level should be to the bottom edge of the filler
plug hole with the vehicle in a level position.
Drain And Refill
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.8
SERVICING AND MAINTENANCE 557

To Help Maintain The Appearance Of Your Spray-On
Bedliner, Follow The Steps Below:
1. Rinse your truck bed out with water to remove anyloose dirt and debris.
2. Mix a mild soap or detergent with water with a soft cloth or brush.
3. Rinse bedliner with water.
4. Once dry, apply a small amount of Mopar Spray-On Bedliner Conditioner to a moist towel or sponge and
wipe over the entire surface of the truck bedliner.
WARNING!
Do not use silicon-based protection products to clean
your bedliner. Silicon-based products can become slip-
pery and may result in personal injury.
Spray-On Bedliners are chemically-resistant to many dif-
ferent types of chemicals (including gasoline, oil, hydraulic
fluids) for short periods of time. If a spill occurs on your
Spray-On Bedliner, rinse the truck out as soon as possible
to avoid permanent damage. Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage a Spray-On
Bedliner. One common condition is when loading a heavy
pallet and dragging that pallet across the floor of the bed.
If a nail or sharp point is exposed under the weight of the
pallet a scratch or tear is possible. While not covered by
your new vehicle warranty, a cosmetic fix to cover the
metal exposed by the scratch is required. To repair a tear or
gouge, follow the directions provided in the Mopar Quick
Repair Kit.
INTERIORS
Seats And Fabric Parts
Use Mopar Total Clean to clean fabric upholstery and
carpeting.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in closed
areas they may cause respiratory harm.

Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
cloth.
2. Dry with a soft cloth.
Leather Parts
Mopar Total Clean is specifically recommended for leather
upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt can act as an abrasive and damage the leather upholstery and
should be removed promptly with a damp cloth. Stubborn
soils can be removed easily with a soft cloth and Mopar
Total Clean. Care should be taken to avoid soaking your
leather upholstery with any liquid. Please do not use
polishes, oils, cleaning fluids, solvents, detergents, or
ammonia-based cleaners to clean your leather upholstery.
Application of a leather conditioner is not required to
maintain the original condition.
NOTE:
If equipped with light colored leather, it tends to
show any foreign material, dirt, and fabric dye transfer
more so than darker colors. The leather is designed for easy
cleaning, and FCA recommends Mopar total care leather
cleaner applied on a cloth to clean the leather seats as
needed.
CAUTION!
Do not use Alcohol and Alcohol-based and/or Ketone
based cleaning products to clean leather seats, as
damage to the seat may result.

WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

WARNING!(Continued)
materials lit or products that can cause spark in or near
the vehicle when removing 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
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with any octane rating, or solely E-85
fuel, or any mixture of these fuels.
For best results, avoid fueling patterns alternating be-
tween E-85 and unleaded gasoline.
When switching fuel types:
•Add 5 gallons (19 liters) or more when refueling.
• Drive the vehicle immediately after refueling for at least
5 miles (8 km).
Observing these precautions will avoid possible hard start-
ing and/or driveability problems during warm up. NOTE:
•
Use seasonally adjusted E-85 fuel (ASTM D5798). With
non-seasonally adjusted E-85 fuel, hard starting and
rough idle following start up may be experienced even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).
• 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
caused by these deposits, a supplemental gasoline addi-
tive, such as Mopar Injector Cleanup or Techron may be
used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formulated
engine oils. These special requirements are included in
Mopar engine oils, and in equivalent oils meeting FCA US
Material Standard MS-6395. It is recommended that engine
oils that are API Certified and meet the requirements of
Material Standard MS-6395 be used. MS-6395 contains
additional requirements, developed during extensive fleet
testing, to provide additional protection to FCA US LLC
engines.
