MAINTAINING YOUR VEHICLE 373

ComponentFluid, Lubricant, or Genuine Part
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requires that you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500 ppm Sulfur
maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15
will provide good performance.
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to operate at
colder-than-normal conditions for prolonged periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel filters.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM
specification D-975.Pickup models, and Chassis Cab models configured with optional B20
capability, are additionally compatible with 20% biodiesel meeting ASTM specification
D-7467.

Oil Change Indicator System — Cummins Diesel
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID).
The oil change reminder will remind the owner to change
the engine oil every 15,000 miles or 500 hours, whichever
comes first, except for the Chassis Cab models and
Pickup models configured with optional B20 capability
that are using B20 biodiesel, which are 12,500 miles or 400
hours, whichever comes first. Failure to change the
engine oil per the maintenance schedule can result in
internal engine damage.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset byreferring to the steps described under “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
Replace the engine oil and oil filter every 15,000 miles
(24 000 km) or six months, or sooner if prompted by the
oil change indicator system. Under no circumstances
should oil change intervals exceed 15,000 miles (24
000 km) or six months, whichever comes first.
NOTE:
•
Under no circumstances should oil change intervals
exceed 15,000 miles (24,000 km) or six months or 500
Hours, whichever comes first.
• Replace the engine oil and oil filter every 12,500 miles
(20 000 km) when running B20 fuel (Chassis Cab
Only).

MAINTENANCE SCHEDULE 381
Page 384 of 406

If Chassis Cab models and Pickup models configured
with optional B20 capability are operated with greater
than 5% levels of Biodiesel, the oil change interval must
not exceed 12,500 miles (20 000 km) under any circum-
stances. See the Fuel Requirements section for more
information regarding operation of Chassis Cab models
and Pickup models configured for use with Biodiesel
blend (B6-B20) fuel meeting ASTM specification D-7467.
Perform Service Indicator — Cummins Diesel
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance isdue, the Electronic Vehicle Information Center (EVIC) or
Driver information Display (DID) will display “Perform
Service”. When the “Perform Service” message is dis-
played on the EVIC/DID it is necessary to have the
emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure for clearing
and resetting the “Perform Service” indicator message is
located in the appropriate Service Information.
