Mari kita bincangkan mengenai "kelikatan" yang merupakan petunjuk terpenting bagiminyak motor. Salah satu petunjuk yang paling biasa untukminyak motor viscosityialah nilai SAE sebanyakminyak motor. What do you usually hear about OW-20 and 5W-30, right? There are five common numbers in front of W, which are 0, 5, 10, 20, and 25. The smaller the number, the lower the applicable ambient temperature. There are also 5 common numbers behind W, which represent the highest temperature applicable to the minyak motor, which are 20, 30, 40, 50, and 60, which represent the viscosity of the minyak motor. This is also the case in motorcycle oil. Most of the minyak motor used by European and American motorcycles such as BMW is 5W-40, 15W-50, Harley 20W-50, KTM 10W-50, and Ducati 15W-50. The minyak motorsyang digunakan oleh Honda dan Kawasaki ialah 0W-30 atau 10W-40. Oleh itu, dapat dilihat bahawa pengeluar kereta Eropah dan Amerika lebih memperhatikan prestasi kenderaan, sehingga kelikatan minyak reka bentuk sedikit lebih tinggi.
