• The aftertreatment diesel particulate filter clean/replace
interval is based on the use of lubricating oils that meet
the Cummins Engineering Standard (C.E.S.) 20081 oil
specification. If a non-low ash lubricating oil meeting the
Amer ican Petroleum Institute (API) perfor mance
classification CI-4/SL and/or C.E.S. 20078 is used, the
service intervals for the aftertreatment systems will be
reduced to 241,000 [150,000 mi] or 5000 hours.
• Replace the primary (or suction side) fuel filter at every
oil change.
• Replace the secondary (or pressure side) fuel filter at
every other oil change.
Oil Drain Intervals
See the following flowchart to determine the maximum rec-
ommended oil change and filter change intervals in kilome-

If yours is a refuse or Mixer/dumper, use table 2. For other
applications, use table 1.
If No -
If the vehicle has not been listed, select the correct oil drain
interval from Table 1.
Table 1—Maximum Oil Drain Intervals
(A) Severe Duty
(If the Vehicle Meets Any of These Conditions)
(B) Normal Duty
(If the Vehicle Meets Both of These Conditions)
Average fuel economy is less than 2.98 km/liter [7.0 mpg], or idle time
is 40 percent or greater, or vehicle operates in dusty areas, or gross
vehicle weight is greater than 27,215 kg [60,000 lbs].
Average fuel economy is greater than 2.98 km/liter [7.0 mpg], and gross

Vehicle uses the severe-duty oil drain interval (A).
Vehicle uses the normal-duty oil drain interval (B).
