INTRODUCTION
Engine oil
Engine oil has been specified as per its performance classification and viscosity classification.
Performance classification under:
American Petroleum Institute (API)
Viscosity classification
The ambient temperature and type of operations at the place where the machine will be used are decisive in deter-
mining Society of Automotive Engineers (SAE) viscosity class.
• Exceeding the low temperature limit will not cause engine damage; but may cause some starting difficulties.
• It is convenient to use universal multi-range oils to avoid the need to change oil due to ambient temperature.
• It is possible to use a synthetic engine oil if the performance and viscosity classifications of the oil correspond to
the recommended mineral oils.
• The oil change intervals used must be the same as those for mineral oils.
• To make starting at temperatures below
0 °C
(
32 °F
) easier, the engine manufacturer recommends SAE 10W-30
oil.
