MAINTENANCE, LUBRICATION AND SERVICE
ENGINE OIL
at high temperatures. An oil is not fully
dened until both the oil quality (see
previous pages) and the viscosity grade
are specied.
Choose the viscosity grade for the
typical ambient temperature for the
application.Multigrade oils have a broad
range that suit operation in changing
temperature. The standard engine oil
weight is 10W/30.
The engine viscosities shown in the
viscosity/temperature table is
recommended.
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 quality standards
recommended in this manual makes the
use of extra oil additives unnecessary,
as these oils already contain a balanced
treatment of additives.
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 ve minutes to allow the
oil to drain back to the oil pan before
checking. Add oil as necessary.
NOTE
DO NOT overll 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.
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.
