Motorcycle Oil Grade Ranking?
1 Answers
Motorcycle oil grade ranking is as follows: 1. Identification: The grade of motorcycle oil can be identified by the markings on the packaging. 2. By quality: The quality grade of motorcycle oil is determined by the API standard (i.e., the standard of the American Petroleum Institute). This is a comprehensive measure of oil quality, with grades ranked from low to high as follows: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN. 3. Look at the letter symbols: From "SA" to "SN", each subsequent letter indicates better performance than the previous one. Additionally, some additives are included in the oil to protect the engine. The further back the letter, the higher the oil grade. Currently, most international brands of oil are SF grade or above.
