Gasoline engine oil
Engine oil is the main factor affecting performance and service life. Use a four-stroke car cleaner.
Recommended oil
Use four-stroke motor oil that meets or exceeds API maintenance level SE or higher (or equivalent). Be sure to check the API service label on the oil reservoir to ensure that the label includes the letters SE or higher (or equivalent)

It is generally recommended to use SAE 10W-30. When the average temperature of the area is within the display range, other viscosities shown in the figure can also be used.
Wash your hands with soap and water after touching the used engine oil.
