Motorcycles usually use gasoline engines, and the quality grade of motorcycle oil is usually suitable for gasoline engine oil quality classification and API classification of API gravity, with specifications of SA, SB, SC, SD, se, SF, SG, SH, SJ, SL and SM.

From "SA" to "SL", with each additional letter, the performance of engine oil will be better than the previous one, and there will be more additives in engine oil to protect the engine. The lower the letter, the higher the quality grade, and most of the oil grades in international brands are above SF grade.

Classification of quality grades of two-stroke motorcycle oil:

The quality classification of two-stroke gasoline engine oil is not completely unified internationally, and JASO's FA, FB and FC classification are generally adopted.

FC is semi-synthetic engine oil, which has the characteristics of less smoke and good cleanliness. 1989, China issued the classification standard of two-stroke gasoline engine oil (GB 763 1 3), which was divided into four types according to characteristics and application occasions, namely ERA, ERB, ERC and ERD, and the quality grades increased in turn.

Two-stroke gasoline engine oil is divided into times, ERB, ERC and ERD according to its characteristics and application occasions.
