Additives for Car Oil

Car oil additives are compounds that are added to engine oil to improve the performance and life of an engine by reducing wear and tear. They can also help with cold starts, reduce friction, prevent corrosion, and keep the engine clean.

Most motor oils today are already fortified with additives, but they can wear out over time or become inadequate for certain conditions. Adding a high-quality oil additive can help extend the life of your engine and keep it running smoothly.

Common Additives for Engine Oil

Common oil additives include detergents, dispersants, anti-foamers, anti-wear agents, viscosity modifiers, extreme pressure additives, and corrosion inhibitors.



  • Detergents – Detergents help to keep the engine clean by keeping the oil free from dirt and deposits, and help to keep the oil from losing its viscosity.
  • Dispersants – Dispersants help to keep the oil clean by suspending dirt and other contaminants in the oil so they can be removed during an oil change.
  • Anti-foamers – Anti-foamers reduce the foaming that can occur in the oil, which can reduce the performance of the engine.
  • Anti-wear agents – Anti-wear agents help to reduce wear and tear on the engine by creating a protective film between moving parts.
  • Viscosity modifiers – Viscosity modifiers help to keep the oil thick and viscous, which helps to reduce friction and wear on the engine.
  • Extreme pressure additives – Extreme pressure additives help to reduce wear on parts that are exposed to extreme conditions, such as high temperature and pressure.
  • Corrosion inhibitors – Corrosion inhibitors help to protect the engine from corrosion and rust.

Is it Necessary to Add Additives to Your Car Oil?

When it comes to maintaining your car and ensuring that it runs smoothly, one of the most important considerations is the type of oil you put in it. While conventional oil is the most common type of oil used, many drivers are beginning to explore the benefits of adding additives to their car oil. But is it really necessary?

The answer is that it depends on the type of vehicle you drive and the condition of your engine. Modern car engines are designed to operate with oil that meets specific standards set by the manufacturer. Adding additives to this oil can improve engine performance and extend the life of the engine.



For newer cars, adding additives to your oil can help lubricate the engine, reduce engine noise, and improve fuel economy. For older cars, additives can help protect against wear and tear and extend the life of the engine. However, it is not always necessary to add these additives, and in some cases, it may even be detrimental.

To determine if additives are necessary for your vehicle, it is important to consult the owner’s manual or speak with a qualified automotive technician. In many cases, the manufacturer may recommend specific additives for your vehicle, and these should be used if possible. A professional mechanic can assess the condition of your engine and recommend the type of oil and additives that are best for your car.




When choosing an additive for your engine oil, it is important to select one that is specifically formulated for your type of engine. Some additives may be beneficial for certain types of engines and damaging to others. Additionally, adding too much of an additive can be damaging to your engine. One time a client brought in a car with coagulated oil paste that we had a hard time to expunge from the engine. This client had used a fake oil additive that underwent a chemical reaction when it came into contact with oil. See? You need to do your own research before using an oil additive.

In conclusion, while additives can be beneficial for some vehicles, it is not always necessary to add them. It is important to consult the owner’s manual or a qualified automotive technician to determine if additives are necessary for your vehicle. Additionally, it is important to select an additive that is formulated for your type of engine and not to add too much. Ultimately, adding additives to your car oil can help protect your engine and ensure that it runs smoothly for years to come.
