features and benefits

Without the lubrication and protection supplied by oil, engines would, quite literally, grind to a halt. So let’s take a closer look at engine oil.

Oil protects engines from corrosion

Acidic corrosion occurs when leftover contaminants from the engine's combustion process react with the metal parts. Oil forms a protective layer, reducing contact with these acidic residues. Engine oil also contains anti-oxidant additives that work on neutralising harmful acidic compounds.

Speed, heavy loads and high temperatures can all lead to abrasion. Without the lubrication that oil provides, the moving components would overheat, causing the engine to seize up.

Tiny particles of dirt and soot that find their way into an engine can cause abrasion issues. Oil is specifically designed to catch such particles and hold them in suspension. These particles are then removed via the oil filter.

Friction is a problem because it reduces engine efficiency and increases fuel consumption and emissions. By reducing friction, oil also reduces excessive heat and engine wear. Oil reduces heat in two ways:

  • It reduces friction between moving components
  • Heat is transferred from the engine parts to the oil

Oil ensures a seal for the gap that's required to allow free movement between pistons and cylinders. Without oil there would be a definite reduction in engine performance.

The thickness of the oil (viscosity) has an effect on reducing engine noise. However, it's important to always use the recommended grade of oil to achieve the best compromise between engine performance and engine noise.

THE COMPLEXITY OF OIL

Fact

With the focus on lower fuel economy and reduced emissions, it’s obvious that most manufacturers favour the more predictable performance qualities of synthetic oils.

As stated, motor oils are produced from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil with a selection of additive to improve certain properties. The standard refined oil is defined by the term ‘mineral’ motor oil.

Synthetic motor oils are made using more advanced refining processes than standard mineral oils. Synthetic oils have a higher purity than conventional mineral oils or semi-synthetic (a blend of mineral and synthetic).

Fully synthetic oils offer:

  • Improved fuel economy
  • Cleaner engine surfaces
  • Improved power input
  • Reduced engine wear
  • Longer oil life
  • Better low temperature flow properties
