Motor oil is described as a kind of oil that lubricates all the moving parts of an engine, by providing a protective film that reduces wear and friction, meaning more power is transferred to the wheels.

It also helps keep engine parts clean and free from harmful deposits, protects engines against Rust and corrosion, and lastly, motor oil cools the engine, by removing excessive heat from the combustion area and down into the oil pan.

Bases of motor oil are:
1. Mineral oil which is a conventional oil that man used for decades, and is produced by crude oil distillation and then mixed with some additives like detergents, viscosity improvers and anti-wear agents. They are relatively inexpensive and deliver average performances;
2. Synthetic oil is characterized as oil that is not derived from raw petroleum. This oil is completely man-made at the laboratories by complex chemical processes, and is more expensive. It has better thermal strength, meaning it is capable of maintaining its viscosity for longer periods of use and under much greater temperatures than conventional mineral oils; and
3. Semi-synthetic oil that refers to the blend of the two earlier mentioned oils (usually 70 to 80% mineral oil and 20 to 30% synthetic oil).
