Engine Lubrication and
Filter Intervals
Oil change intervals for normal and severe
duty applications.
See the following table to determine the
maximum recommended oil change and oil
filter change intervals in miles (kilometers)/
hours or months, whichever comes first.
Replace the fuel filters (pressure and
suction side) at the same interval as the oil
and oil filter are changed.
NOTE
Idle time must be factored into calcu-
lating average vehicle speed.
The intervals are based on the vehicles
average speed/miles per hour (mph)
(Includes idle time). Locate your vehicles
average vehicle speed/mph in the first
column to determine the oil change/filter
change interval to use. If the vehicle is
equipped with an hour meter, it is
acceptable to use the engine hours listed
for the oil change and oil filter change
interval.
If the average vehicle speed/mph is
unknown and the vehicle is not equipped
with an hour meter:
1. See the "Typical Application(s)"
column. Use the lowest interval listed
for your application.
2. Connect an electronic service tool.
The electronic service tool can
provide the average vehicle speed
recorded by the engine control
module (ECM). This can be done at a
PACCAR Authorized Repair
Location.
