Wheel works

The main function of engine oils is to reduce friction between engine parts. Even short periods of engine operation in dry (unlubricated) conditions can cause engine failure.

Functions of a high quality engine oil

• Disperses excessive heat between frictioning engine parts.
  
• Keeps engine parts clean
  
• Ensures adequate power to engine parts

Causes of loss of functional performance of engine oil

• Oil contamination by soot, dust, metal particles, etc.
  
• Oxidation caused by high oil temperature (contact with hot engine parts).
  
• Reduction in quantity due to combustion, evaporation, etc. of engine oil
