Engine oil is the lifeblood of every engine in an automobile, and adding engine oil additives is the greatest approach to improve the quality of the oil. Chemical substances known as engine oil additives are created to alter or modify the properties of engine oil in order to increase performance or solve particular engine-related difficulties. These additives are combined with the base oil to produce a unique mixture that offers more advantages than the base oil by itself. The following are a few types of common engine oil additives:

1. Anti-Wear Additives: These additives form a protective layer on metal surfaces, reducing friction and wear between moving parts. They are especially important in older engines or high-stress conditions where metal-to-metal contact is more likely.

2. Viscosity Index Improvers: The resistance of the oil to flowing at various temperatures is referred to as viscosity. In order to maintain the oil's effectiveness in both cold-start situations and high-temperature operations, viscosity index improvers help stabilise the oil's viscosity across a variety of temperatures.

3. Anti-Foaming Additives: These additives stop the oil from foaming, which can restrict oil flow and cause a loss of lubrication. Foam might develop as a result of air entrainment or the rapid movement of engine parts.

4. Corrosion Inhibitors: These additives protect engine components from corrosion and rust, particularly in areas exposed to moisture or acidic combustion by-products.

5. Friction Modifiers: By using these additives, friction is decreased even more, potentially improving fuel efficiency and reducing wear on engine components.

6. Pour Point Depressants: They help lower the temperature at which the oil starts to solidify, ensuring better oil flow and pumpability in colder climates.

7. Seal Swell Agents: In older engines with worn seals, these additives are used to condition and expand seals, avoiding or minimising oil leaks.

8. Anti-Oxidants: These additives aid in preventing oil oxidation, which can cause oil to thicken and produce hazardous sludge and deposits.

All the engine oil additives are Different to operate therefore one should Always understand the need and read the instruction manual Properly before using any kind of additives in the engine .
