Why we need Engine Oil

The primary function of an engine oil is to act as a lubricant. All mechanical devices require lubrication to prevent over-heating and damaging wear. Where any two solid surfaces move in contact with each other, the friction created generates heat and causes wear. High quality engine oil, such as those produced by Castrol, will lubricate, protect, cool, clean and seal your engine.

Engine oils:
  • reduce friction and wear for efficient engine operation and long life.
  • remove heat from the engine to prevent it overheating.
  • prevent deposits and corrosion to keep the engine clean.
  • contribute to energy savings and clean combustion.

So now you know why engine oil so important.
