What is a lubricant?
Like human blood, oil is the blood of the engine. For full functional operation, the engine requires high-quality oil. Various oils used in the engine to operate such as fuel, transmission oil, lubricant.
Fuel is the key to engine operation addition of fuel runs the engine. The engine stays in operating mode until getting fuel.
When the engine runs, some unexpected factors occur, such as friction, vibration, corrosion, the heat that decreases the life of the engine.
To reduce friction, heat dissipation, reducing vibration of the engine, noise removal, increase the efficiency of the engine, a substance is used called lubricant.
Lubricants prevent the engine from friction, corrosion, less vibration. It cools the engine.
If there is no engine oil on the operation of the engine. It will produce noise, higher vibration. The great heat problem is that it may cause severe damage to the engine may cause a fire.
Without lubricant or engine oil, no vehicle is safe for smooth operation.
Lubricants give smooth engine operation, provides longer life, less fuel consumption, dissipating heat increases engine efficiency and durability.
Benefits of using lubricant
Using lubricants benefits can be described in a few lines. The engine gets a long life, excellent efficiency. Some of the vital interests are discussed below
- Reduce friction: Movement of the motor causes friction of the mechanical part that makes friction. If lubricant is used, the resistance is reduced, saving the engine life.
- Noise reduction: When lubricant or engine oil used for lubrication, less friction occurs that reduces noise on engine operation.
- Reduce corrosion: Using lubricant decrease friction engine decays very slowly. It gets longer life; otherwise, corrosion will make short life.
- Rust prevention: Lubricant prevents mechanical parts from getting rust.
- Cooling agent: At the operating time, the heat produced inside the system lubricant absorbs the heat, saves the engine, and increases the efficiency of the engine.
- Cleaning: Lubricant cleans the dirt of the engine. When you buy a vehicle, the engine contains small particles that need to be cleared for full operation. There is no other method to clean it; it is washed by the rotation of the engine. If the engine has excellent lubrication, it absorbs the particles released by the engine; thus, the way lubricant cleans the engine.
- Seal the leakage: Engine oil seals the leakage if there is leakage inside the system.
Properties of lubricants
The features of oils are
- High flashpoint
- Prevention from corrosion
- Pour point & cloud point
- Anti-freeze property

Classification of lubricants
Based on source
There are two types of lubricants based on source viz. i) mineral-based lubricants ii) synthetic-based lubricants
i) Mineral-based lubricants:
Mineral-based lubricants produced through crude oil after refining. Generally, refined crude is not suitable to use as lubricant additives added to make mineral-based lubricants usable.
Usually, 10% of additives added to refined crude oil to make it suitable for lubrication.
ii) Synthetic based lubricants:
Synthetic based greases are artificially chemically compound to use as lubricants.
Petroleum components are compounds with chemical treatment; there is needed to add additives to make synthetic lubricant usable.
Based on using
i) Automotive lubricants:
Automotive lubricants are chemical compounds to use only for automotive applications. There are also varieties in automotive lubricants; all the engines are not the same size or same type.
So that different engine needs different types of lubricant. All the automotive grease is not the same; they have a specific grade number.
Motorcycle, car, bus, truck vehicles have different grades engine oil or lubricant.
ii) Industrial lubricants:
Industrial lubricants are special treatment for industrial use only. For industrial machinery, high-quality lubricant requires, those lubricants are chemically treated for industrial use.
iii) Special lubricants:
Grease is a unique lubricant mixer of oil or other lubricant combination of soap foam or semisolid typically made for particular purpose usage. Particular purpose lubricants are formulated for a single lubrication job.
Based on grade
i) Multigrade lubricants:
Multigrade lubricants have multi-grade viscosity at cold and hot condition both. The first number is followed for winter “W,” and the second one is for the burning state. For example, 5W-30
ii) Monograde lubricants:
Monograde lubricants are not for winter or hot conditions. It is formulated for only one term, either hot or cold situation.
Based on condition
i) Solid lubricants:
Solid lubricants are used as powder formed for lubrication to reduce friction. Example: The most commonly used stable oils are graphite, boron nitride, molybdenum disulfide.
ii) Semi-solid lubricants:
Greases, vaseline, and waxes are semi-solid lubricants.
iii) Liquid lubricants:
Most of the applications on your vehicle live are used liquid lubricants.
What are the additives?
Additives are those compounds that are used to enhance the performance of lubricants to keep the engine functioning.
- Viscosity modifier
- Corrosion inhibitor
- Rust inhibitor
- Ant wear agent
