What is the purpose of engine oil?

Motor oil provides lubrication to the many moving parts of an engine, which helps to avoid damage and keep your engine running smoothly. Each time your engine runs, by-products from combustion are collected in your engine oil.

What is the main function of engine oil?

The main role of engine oil is to lubricate the engine parts, which are in constant friction. It thus reduces friction which tends to increase wear & tear of engine parts. The energy is lost through combustion and the friction between mechanical parts causes the engine temperature to rise.

What are the 3 main purposes of engine oil?

Oil. Its basic functions within an engine include reducing friction, cooling, sealing, cleaning, and serving as protection for moving parts.

What are the characteristics of engine oil?

The main requirements for an engine oil are defined temperature-viscosity properties, protection against wear and corrosion, keeping the engine clean, holding particles like soot or abrasives in suspension, yield strength under compression and many more.

Choose an oil with the vehicle manufacture’s recommended viscosity rating (check your owner’s manual). Viscosity is an oil’s ability to flow at different temperatures. The two most common viscosities (a.k.a. weights) are SAE 5W-30 and SAE 10W-30. The lower the number, the thinner the oil.

What are the 6 functions of lubricating oil?

There are 6 Basic Functions of a Lubricant/Oil.

  • Lubrication – Provide a film between moving parts.
  • Cooling – Heat transfer media.
  • Sealing – Filling in uneven surfaces.
  • Cleaning – Holding contaminants in suspension.
  • Dampening & Cushioning – Of components under high stress.
  • Protection – From oxidation & corrosion.
