Filter Specifications
PACCAR is not responsible for problems
caused by non-genuine filters that do not
meet PACCAR performance or durability
requirements.
Contact your local PACCAR authorized
repair location for specific part numbers.
Fleetguard filters are standard on new
PACCAR engines. PACCAR recommends
their use.
Fleetguard products meet all PACCAR test
standards to provide the quality filtration
necessary to achieve the engine's design
life. If other brands are substituted, the
purchaser should ensure the filter
specification meet or exceed the
Fleetguard specifications.
CAUTION
Use of non-genuine PACCAR oil filters
can cause severe engine damage.
Engine Lubricating Oil
Recommendations and
Specifications
A major factor in maintaining engine
performance and durability is the proper
use of quality engine lubricating oils used
in conjunction with the appropriate oil drain
and filter change intervals. Attempting to
extend the oil and filter change interval
beyond the manufacturer's
recommendations may decrease engine
life due to factors such as corrosion,
deposits, and wear.
See "Engine Lubrication and Filter
Intervals" to determine which oil drain
interval to use for an application.
NOTE
It is the operator’s responsibility to fol-
low these recommendations to ensure
that the engine warranty is not affect-
ed.
The primary PACCAR recommendation is
for the use of SAE 10W-30 API CK-4 or
CJ-4 multigrade lubricating oil for normal
operation at ambient temperatures above
