Pogovorimo se o "viskoznosti", ki je najpomembnejši kazalnikmotorno olje. Eden najpogostejših kazalnikovmotorno olje viscosityje vrednost SAE zamotorno olje. 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 motorno olje, which are 20, 30, 40, 50, and 60, which represent the viscosity of the motorno olje. This is also the case in motorcycle oil. Most of the motorno olje 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 motorno oljeski jih uporabljata Honda in Kawasaki so 0W-30 ali 10W-40. Zato je mogoče videti, da evropski in ameriški proizvajalci avtomobilov večjo pozornost posvečajo zmogljivosti vozil, zato je viskoznost konstrukcijskega olja nekoliko višja.
