Engines
if oil pressure does not build within approxi-
mately ten seconds. Check to determine the
cause of the problem. Operating the engine with
no oil pressure will damage the engine.
6. It is not necessary to idle the engine before en-
gaging or starting the operation, but load should
be applied gradually during the warm-up period
until the oil temperature reaches 140°F (60°C).
7.
Apply load gradually during the warm-up period.
NOTICE
If the oil pressure gauge indicates no oil pres-
sure, shut down the engine within approximately
ten seconds to avoid engine damage.
8. Check the oil pressure gauge for any drop in lu-
bricating oil pressure or mechanical malfunction
in the lubricating oil system. Minimum oil pres-
sure at idle is 7 psi (50 kPa).

Cold-Weather Starting

Electronic engines do not normally require special
starting aids.
See the engine manufacturer's operation manual for
starting aids that are approved for specific engines.
Starting After Extended
Shutdown or Oil Change
Before engine start-up, complete the engine pretrip
and post-trip inspections and maintenance proce-
dures in Chapter 11.
NOTICE
Failure to eliminate water-diluted lubricating oil
may lead to serious engine damage at startup.
An engine in storage for an extended period of time
(over winter, for example) may accumulate water in
the oil pan through normal condensation of moisture
on the internal surfaces of the engine. Oil diluted by
water cannot provide adequate bearing protection at
start-up. For this reason, change the engine oil and
filters after extended storage.

Engine Break-In

Each engine must pass a full-load operating test on
a dynamometer before shipment, thereby eliminating
the need for a break-in. Before running the engine
for the first time, follow the instructions in the engine
manufacturer's operation manual specific to your en-
gine.

Engine Operation

Safety and Environmental
Considerations
All Freightliner diesel engines comply with the re-
quirements of the Federal (U.S.) Clean Air Act. Once
an engine is placed in service, the responsibility for
meeting local jurisdictional regulations is with the
owner/operator.
IMPORTANT: EPA emissions regulations apply
to vehicles domiciled in Canada and the U.S. at
the time of printing this manual. Vehicles that
are domiciled outside of the U.S. and Canada
may not have engines with an emission after-
treatment system that is compliant with EPA
regulations, depending upon local statutory
emissions guidelines.
NOTICE
It is extremely important that the following guide-
lines be followed for vehicles with EPA07 or
newer engines, or damage may occur to the af-
tertreatment device, and the warranty may be
compromised.
•
Use ultralow-sulfur diesel with 15 ppm sul-
fur content or less.
•
Do not use fuel blended with used engine
lube oil or kerosene.
•
Use only engine lube oil with a sulfated ash
level less than 1.0 wt %; currently referred
to as CJ-4 oil.
Adequate maintenance of the engine and the diesel
particulate filter (DPF) are the responsibility of the
owner/operator, and are essential to keep the emis-
sion levels low. Good operating practices, regular
maintenance, and correct adjustments are factors
that will help keep emissions within the regulations.
