Using Oil Additives in Your Engine: What You Need to Know

car engine

The use of oil additives in engines has been debated among vehicle enthusiasts for years. While some believe these products can provide various benefits, such as improved performance, reduced wear, and extended oil life, others argue that they can potentially cause damage to the engine. This blog section aims to provide a comprehensive look at the subject, discuss the potential risks and benefits of using oil additives, and how professional fuel fixing services can help in case of any issues.

What are Oil Additives?

Oil additives are chemical compounds added to engine oil to enhance its properties and provide additional benefits. These additives can be classified into two main categories: those that enhance the existing properties of the oil, such as viscosity modifiers, and those that provide new properties, such as anti-wear or friction-reducing agents. Some of the most common oil additives include:

1. Viscosity Modifiers

These additives help maintain the oil’s viscosity at high temperatures, allowing it to flow more easily and provide better lubrication.

2. Anti-Wear Agents

These compounds form a protective layer on the engine’s metal surfaces, reducing friction and wear.

3. Corrosion Inhibitors

These additives protect the engine from rust and corrosion by neutralising acidic by-products of combustion.

4. Detergents

These compounds help keep the engine clean by preventing sludge buildup, varnish, and other deposits.

5. Dispersants

These additives help suspend and disperse the oil’s contaminants, preventing them from settling and forming deposits.

Are Oil Additives Bad for Your Engine?

The answer to this question is not a simple yes or no, as the effects of oil additives on an engine can vary depending on the type and quality of the additive, the specific engine, and the vehicle’s overall maintenance. However, there are some potential risks associated with using oil additives, which include:

1. Incompatibility with the Engine Oil

Some oil additives may not be compatible with the specific type of oil your engine requires or may interact negatively with the existing additives in the oil. This can lead to reduced performance, increased wear, or even engine damage.

2. Overdosing

Adding too much of an oil additive can have negative consequences, such as causing the oil to become too thick or thin, leading to poor lubrication and potentially damaging the engine.

3. Voiding Warranty

Some vehicle manufacturers may void the warranty if oil additives are used, as they believe that these products can potentially harm the engine.

How Professional Fuel Fixing Can Help

If you suspect that your engine has been damaged due to oil additives, it is crucial to seek professional help to address the issue. A professional fuel fixing service can help by:

1. Draining and Flushing the Engine

If the issue is caused by an incompatible or overdosed oil additive, a professional fuel fixing service can drain the contaminated oil and flush the engine to remove any residue before refilling it with the appropriate oil.

2. Diagnosing and Repairing Issues

If oil additives have resulted in engine damage, such as worn components or leaks, a professional mechanic can diagnose the issue and recommend the necessary repairs.


While oil additives can provide some benefits, they can also pose risks to your engine if not used correctly or if they are of poor quality. It is essential to do thorough research and consult with a professional mechanic before using any oil additives to ensure they are compatible with your engine and provide the desired benefits. In case of any issues arising from oil additives, professional fuel fixing services can help diagnose and resolve the problem, ensuring the longevity and optimal performance of your engine.
