  • One class viscosity engine oil
    · This oil has only one kind of features which works well in low temperature or in high temperature like SAE 10W, SAE 20, SAE 30 etc.
    · This oil is used in place where there is not much temperature change.
  • Diverse class viscosity engine oil
    · For example of SAE15W-40 product, it has two features of SAE 15W(working well in low temperature) and SAE 40(working well in high temperature)
    · Oil is stiff in low temperature and watery in high temperature. Diverse class viscosity engine oil is a bit watery in low temperature and is not too watery in high temperature.
    It is most popularly used product in the world.
