Engine Compartment Overview

Engine Oil

Engine oil is an important factor
determining engine performance and
longevity. Be sure to use only the specified
oil and oil filters. The engine oil level must
be checked and the oil should be changed
regularly according to the Maintenance
Schedule.
The engine oil performs the following
important functions:
It prevents engine parts from
becoming worn.
Vehicle Care
It cools engine parts.
It cleans engine parts.
It seals the combustion chambers and
prevents rust.
Replace the engine oil at regular intervals.
When particulate matter (PM) has
accumulated to a preset level in the diesel
particulate filter (DPF), the filter is
automatically regenerated through
combustion. To make this regeneration
(combustion) possible, a small amount of
fuel is injected into the engine combustion
chamber after firing. This causes fuel to
gradually become mixed with the engine oil,
and the engine oil level may rise beyond
the original level. This does not indicate a
malfunction of the engine.
Access to the Engine
Access to the engine oil dipstick is located
on the engine left side after tilting the cab.
See Cab Tilting 0 192.
