2.4 Oil
Important
• The engine may be damaged if operated with improper oil
level.
• Do not exceed the MAX level because a sudden increase in
engine rpm could be caused by its combustion.
• Use only the recommended oil to ensure adequate protection,
efficiency and service life of the engine.
• The use of lubricants other than recommended may shorten
the engine life.
• Viscosity must be appropriate to the ambient temperature to
which the engine is to be exposed (Par. 2.4.1).
Danger
• Prolonged skin contact with the exhausted engine oil can
cause cancer of the skin.
• If contact with oil cannot be avoided, thoroughly wash your
hands with soap and water as soon as possible.
• For the exhausted oil disposal, refer to
Par. 6.8 DISPOSAL and SCRAPPING.
2.4.1 SAE oil classification
• In the SAE classification, oils are identified according
to viscosity without considering any other qualitative
characteristic.
• The code is made up of two numbers. The first number
refers to the viscosity when cold, for use during winter ("W"=
winter), while the second number is for viscosity at high
temperatures.
2.4.2 Reversing gear oil
NOTE: Refer to the technical documentation of the reversing gear supplied with the engine.
