Oil Additives; Oil Consumption; Oil Change - PREVOST H3-41 Maintenance Manual

SECTION 01 : ENGINE

2.3.6 Oil Additives

CAUTION
Extra oil additives must never be added to
any engine oil used. Additives such as break-
in oils, top oils, graphitizers, and friction
reducing liquids are not necessary and may
even harm the engine.
Using oils to the
recommended in this manual makes the use of
extra oil additives unnecessary, as these oils
already contain a
additives.

2.3.7 Oil Consumption

Once the engine is stopped, check the oil level
daily. If the engine has just been stopped and it
is warm, wait approximately five minutes to allow
the oil to drain back to the oil pan before
checking. Add oil as necessary.
CAUTION
DO NOT overfill engine with oil.
All diesel engines are designed to consume
some oil, so it is normal to add oil periodically.
An engine used in heavy-duty operation will
consume more oil than one in normal operation.

2.3.8 Oil Change

WARNING
A hot engine or engine oil can be dangerous.
Serious burns can result from contact with a
hot engine or oil. Take precautions when
draining the oil. Wear gloves or let the engine
cool down before draining.
WARNING
When draining the oil, use the proper tools
and keep away as far as possible. Raise the
elbow so the forearm is parallel to the ground
to prevent oil running down the arm, causing
burns.
