Hitz egin dezagun adierazle garrantzitsuena den "biskositateaz"motor olioa. Ren adierazle ohikoenetako batmotor olioa viscosity-ren SAE balioa damotor olioa. 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 motor olioa, which are 20, 30, 40, 50, and 60, which represent the viscosity of the motor olioa. This is also the case in motorcycle oil. Most of the motor olioa 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 motor olioasHonda eta Kawasaki-k erabiltzen dituztenak 0W-30 edo 10W-40 dira. Horregatik, Europako eta Amerikako auto fabrikatzaileek ibilgailuen errendimenduari arreta handiagoa eskaintzen diotela ikus daiteke, beraz, diseinu olioaren biskositatea zertxobait handiagoa da.
