Our Key FAQS

Got a question about Castrol or engine oil in general? Please see the answers below.


  • As a lubricant they reduce the friction and wear that occurs when engine parts move against each other, for example between the cylinder walls and piston rings, or the camshaft lobes and followers/lifters.
  • As a coolant they absorb and transfer the heat produced in the engine combustion chambers and piston undercrown area, cooling the engine and helping prevent overheating.
  • As a sealant they seal the space between the piston ring and the cylinder wall to prevent combustion pressure (engine power) from escaping.
  • As a detergent they prevent waste matter resulting from combustion and impurities from sticking to the engine interior, helping to keep it clean.
  • As a rust inhibitor they neutralise acids produced by combustion gases, preventing rusting and corrosion.

Mineral and synthetic based oils are mostly derived from crude oil or its refined components. Mineral base oils are produced during normal crude oil refining process and are enhanced with chemical additives. Some synthetic base oils are produced by further refining and chemically altering these mineral base oils. Other types of synthetic base oils are made by using special refinery products to tailor-make specific and unique molecules.

Synthetic engine oils are able to:
  • Operate at much higher temperatures for longer.
  • Resist oxidation better than mineral oils leading to less wear and longer engine life.
  • Be used for longer or extended drain intervals.
  • Provide quicker oil circulation at start-up which contributes to improved fuel economy due to less energy being wasted through viscous drag.
