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). The engine oil change indicator
system is duty cycle based, which means the engine oil
change interval may fluctuate depending on your per-
sonal driving style. Driving styles such as frequent stop
and go type driving or extended idle time can increase
the frequency of the engine oil change. This is the result
of more frequent regeneration of the exhaust after treat-
ment system, which can decrease the life of the engine oil.
Failure to change the engine oil per the maintenance
schedule can result in internal engine damage.
For information on resetting the Oil Change Indicator
message, refer to “Oil Change Due” under “Electronic
Vehicle Information Center (EVIC)/EVIC Warning
Lights” 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 circum-
stances 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).
