Engine Lubrication and
Filter Intervals
See the following table to determine the
maximum recommended oil change and oil
filter change intervals. Intervals are based
on oil capacity and fuel economy.
Oil drain intervals for engines running
biodiesel blends greater than B5 must
reduce the oil drain interval to one half of
the value obtained in the table below.
The use of Centinel™ or any type of
blending is prohibited.
Maintaining the correct oil and filter change
interval is a vital factor in preserving the
integrity of an engine. Lubricating oil filters
must be changed when the oil is changed.
Drain the oil and change the lubricating oil
filter according to whichever occurs first.
• Engine distance
• Run time
• 18 months
NOTE
A Maintenance Monitor feature is
available through the engine's ECM.
This feature can be enabled by a PAC-
CAR Authorized Repair Location.
CAUTION
Extending the oil and filter change in-
terval beyond the recommendations
will decrease the engine life due to
factors such as corrosion, deposits,
and wear. Engine oil filters capture dirt
and remove deposits from the oil to
prolong the life of internal moving com-
ponents. Follow the oil and filter
change intervals as recommended in
this section of the manual. Failure to
comply may result in equipment or
property damage.
