What are the components of motor oil?
Engine oil is comprised of two basic components–base oils and additives. The base oils constitute 70-90 percent of the total and are created from natural gas or crude oil, while additives round out the remaining 10-30 percent and can be variety of things. These additives include among other things: Dispersants.
What are the 5 functions of oil?
The seven primary functions of motor oil
- Minimize friction and reduce wear. The most common and essential function of motor oil is to minimize friction and wear between components. …
- Clean. …
- Cool engine parts. …
- Form a seal. …
- Dampen shock. …
- Prevent corrosion. …
- Transfer energy.
What does the 5 mean in motor oil?
The first number describes viscosity at low temperatures. The second number refers to viscosity at normal engine operating temperatures. Some examples: the “5” in a 5W-30 motor oil will protect an engine down to an air temperature of about -25 degrees Fahrenheit.
What is the most common motor oil?
Conventional oil is the most commonly used type of oil.
What is the function of the motor 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 does motor oil do in a car?
The primary purpose of motor oil (also known as “engine oil”) is to lubricate all of the moving metal pieces inside the engine of your car, truck, or SUV.
What is 80% of motor oil?
Base oil makes up nearly 80% of a motor oil formulation and additives make up the remaining nearly 20%. The chemically engineered molecules in synthetic base oil have more uniform properties while the molecules found in conventional base oil differ in shape and levels of impurity.
What does the 5 mean in 5W-30 oil?
5w30 motor oil has a winter viscosity grade of five, meaning it’s less viscous (less thick) at very low temperatures compared to, say, 10w30. It has a hot viscosity grade of 30, which means it is less viscous at high temperatures than an oil such as 5w50.
Is 5W or 10W thicker?
A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures.
Which is best engine oil?

What is conventional motor oil?
Conventional motor oil is a lubricant that is derived directly from crude oil. It has excellent properties that allow it to provide lubrication at high temperatures, as well as maintaining its stability over long periods of time.
Who makes Castrol oil?
Castrol is a U.K.-based producer of industrial and automotive lubricants for a global market. The company was founded by Charles Wakefield in London in 1899. 8 It was acquired by BP in 2002. 9 Castrol lubricants are sold in automotive stores and gas stations in over 150 countries.
