referring to the steps described under “Instrument Cluster
Display” 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).
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 circumstances. 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 is due,
the instrument cluster will display “Perform Service”.
When the “Perform Service” message is displayed on the
instrument cluster it is necessary to have the emissions
maintenance performed. Emissions maintenance may in-
clude replacing the Closed Crankcase Ventilation (CCV)
filter element. The procedure for clearing and resetting the
“Perform Service” indicator message is located in the
appropriate Service Information.
