What does oil viscosity mean?

Viscosity tells how “viscous” the engine oil is at a given temperature. However, it initially says nothing about the quality of the engine oil.

  • Low viscosity = low resistance to deformation
    “Thin viscosity” (example: water)
  • High viscosity = high resistance to deformation
    “viscous” (example: honey)

Engine oil viscosityWhile engine oil with low viscosity flows more easily and is easier to transport through the engine, engine oil with high viscosity can withstand higher mechanical beslatings.
