oil temperature Ram 2500 2016 Diesel Supplement

Oils with a high ash content may produce damaging
deposits on cylinder head valves and/or aftertreatment
system damage. A maximum sulfated ash content of 1.00
mass % is recommended for all oil used in the engine.
The same oil change interval is to be followed for
synthetic oil as for petroleum based oil. Also, synthetic oil
must meet the same performance specifications as petro-
leum oil.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
In ambient temperatures above 0°F (-18°C), we recom-
mend you use SAE 15W-40 engine oil such as MOPAR,
Shell Rotella and Shell Rimula that meets FCA MaterialStandard MS-10902 and the API CJ-4 engine oil category
is required. Products meeting Cummins CES 20081 may
also be used. The identification of these engine oils is
typically located on the back of the oil container.
In ambient temperatures below 0°F (-18°C), SAE 5W-40
we recommend you use
syntheticengine oil such as
MOPAR, Shell Rotella and Shell Rimula that meets FCA
Material Standard MS-10902 and the API CJ-4 engine oil
category is required.
CAUTION!
Failure to use SAE 5W-40 synthetic engine oil in
ambient temperatures below 0°F (-18°C) could result
in severe engine damage.

5. Place the shift lever momentarily into each gear posi-tion (allowing time for the transmission to fully en-
gage in each position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill.Use
ONLY the specified fluid (see Fluids, Lubricants, and
Genuine Parts for fluid specifications). After adding
any quantity of oil through the dipstick tube, wait a minimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at 60-70°F / 16-21°C for 68RFE transmis-
sion, or 68-86°F / 20-30°C for AS69RC transmission. Only
use the COLD region of the dipstick as a rough reference
when setting the fluid level after a transmission service
or fluid change. Re-check the fluid level, and adjust as
required, once the transmission reaches normal operating
temperature.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
