The Composition of a Lubricant

The Composition of a Lubricant

A lubricant is a mixture – a blend – of two key components of oil: Base Oil and Additives.

Base Oil

A lubricant exists for 70%-90% out of base oil. It’s is the foundation of a lubricant. There are three types of base oil:

  • mineral base oil
  • semi-synthetic base oil
  • synthetic base oil

Mineral oils are refined from crude oils, synthetic oils are completely chemically built and semi-synthetic oils are a mixture of mineral and synthetic base oils.

The base oils control the thickness – or “viscosity”- of an oil. This is important because a lubricant needs to be thin enough to reach all the different car parts, but not too thin so it can still protect against friction between the metal car parts.


The other 10%-30% of a lubricant consists of additives. These are a combination of several chemical components that are blended into the base oil to enhance its stability and to add specific performance features.

Additives contain different elements that will extend the life of the lubricant and as a result, the life of the engine.

Without the additives, the oil would get contaminated, break down leak out and not properly protect engine parts at all operating temperatures.

Over the last 10-15 years it has become necessary to develop even more adequate additive packages to create innovative lubricants that follow the latest technological evolutions in engine design.
