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 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).
