Vamos falar sobre a "viscosidade", que é o indicador mais importante deóleo de motor. Um dos indicadores mais comuns deóleo de motor viscosityé o valor SAE deóleo de 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 óleo de motor, which are 20, 30, 40, 50, and 60, which represent the viscosity of the óleo de motor. This is also the case in motorcycle oil. Most of the óleo de 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 óleo de motorsusados pela Honda e Kawasaki são 0W-30 ou 10W-40. Portanto, pode-se ver que os fabricantes de automóveis europeus e americanos prestam mais atenção ao desempenho do veículo, portanto, a viscosidade do óleo de design é ligeiramente superior.
