Performance classification according to
It is convenient to use universal multi-range oils to avoid oil changes due to ambient temperature.
Exceeding the upper temperature limit, considering the reduced lubricating capabilities of the oil must not last for long.

10W/30 10W
Exceeding the lower temperature limit does not result in damage to the engine; it can only cause some starting difficulties.
5W/40
Use of permissible oils according to API: CK-4 / CJ-4 or better quality.
5W/30
To determine the SAE (Society of Automotive Engineers) viscosity class, the ambient temperature and type of operation where the machine is used are decisive.
