A classificação numérica dos óleos de motor - como 20W50, 15W40 ou 5W30 - muitas vezes passa despercebida, mas ela é essencial para entender o desempenho ea proteção do motor. Esses números indicam a viscosidade, ou seja, o grau de espessura e fluidez do óleo em diferentes temperaturas. Em um teste visual, é possível ver claramente como cada tipo se comporta: óleos mais espessos descem lentamente, enquanto os mais finos escorrem com facilidade, adaptando-se melhor a motores modernos e condições.
