2020 Ram 3500 oil additives

SERVICING AND MAINTENANCE403
Engine oil not designated by the FCA or
Cummins Material Standards and API CK-4
should not be used, as engine and exhaust
system durability may be compromised. 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 “Engine Compartment” in
“Servicing And Maintenance” for further
information.
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended 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 addition 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 disposable 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 ensure most efficient
service. Mopar engine oil filters are high quality
oil filters and are recommended.
ENGINE AIR CLEANER FILTER
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.

458TECHNICAL SPECIFICATIONS
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if
stored properly, provides for protection against
fuel oxidation for up to six months.
Fuel Water Separation — Must Use Mopar/
Cummins Approved Fuel Filter Elements
You must use Mopar/Cummins approved fuel
filter elements in both your engine mounted
filter and frame mounted filter.
Biodiesel fuel has a natural affinity to water and
water accelerates microbial growth. Your
Mopar/Cummins filtration system is designed
to provide adequate fuel water separation
capabilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for
both storage and operation. Precautions can be
necessary at low ambient temperatures, such
as storing the fuel in a heated building or a
heated storage tank, or using cold temperature
additives.
Fuel In Oil Dilution — Must Adhere To
Required Oil Change Interval
Fuel dilution of lubricating oil has been
observed with the use of biodiesel fuel. Fuel in
oil must not exceed 5%. To ensure this limit is
met your oil change interval must be
maintained to the following schedule:
Ram PickUp 2500/3500 Only — 15,000 Miles*
(*unless otherwise notified with a oil service
message)
CAUTION!

Under no circumstances should oil change
intervals exceed 15,000 miles (24 000 km)
pickup or 12,500 miles (20 000 km) chassis
cab if operation occurs with greater than 5%
biodiesel blends. Oil change intervals should
not exceed 6 months in either case. Failure
to comply with these Oil Change require -
ments for vehicles operating on biodiesel
blends up to B20 may result in premature
engine wear. Such wear is not covered by the
New Vehicle Limited Warranty.

B20 Biodiesel capable: The engine may
suffer severe damage if operated with
concentrations of Biodiesel higher than
20%.
