Are Oil Additives Good for Your Car’s Engine

Oil additives may improve the work of your engine, but they are not completely necessary for it to work properly. Many people add them to the oil, so they can increase or stabilize some features, especially in older vehicles. Of course, they can also help reduce friction and extend the life of car parts. According to some estimates, certain additives can extend the life of your oil by up to 50%, due to the additives that are responsible for it. But many enthusiasts and mechanics still do not adore them much and consider it an unnecessary waste of money. Although there is no concrete evidence for any of the claims, the use of additives remains the choice of the vehicle user.

Of course, all this depends on the quality of the products. Initially, they can protect your engine from corrosion, and build-up, and help it to cool down. Chemical additives are added which are certainly not the same for every car. It is best to buy them from authorized sellers and pay attention to the manufacturer. If you look at, you can see what they are used for and how they can positively affect the operation of the vehicle.

If you are thinking, you can always consult your mechanic, who can give you appropriate advice.

What is an oil additive?


As we have already explained, this is an accessory that improves the performance of your engine. Some cars can do without them, but sometimes it is necessary to use additives. There are different types, which have different uses. Engine oil burns and can stick to other parts of the engine. This is why certain defects occur. Although you need to change the oil at certain times, the additives prolong it, making the whole situation more economical for you.

Some of the additives improve the viscosity, others protect the engine from wear, while others are a combination of several features, for a better end effect.

Why are oil additives good for your vehicle?

They improve much of the engine’s function and prevent oil oxidation. As time goes on, the quality of the engine oil decreases, so you either need to change or extend its life with the help of these supplements. If you do not do any of these, you run the risk of your vehicle breaking down prematurely, heating up, or corroding. Additives are an economical choice to extend the time between two oil changes. Care must also be taken to use the specified amount to avoid secondary damage as a result of the additives. Of course, do all this in coordination with a mechanic, or someone who is a good connoisseur of these things.

Facts you need to know about oil additives


It is always good to find out as much as you can about the things you want to do for your car.

1. Oil additives work best on older motor vehicles. The newer ones have a more advanced engine oil regulation system.
2. Additives decompose over time, so regular replenishment may be required. Failure to do so may result in further damage.
3. These additives work immediately, even on the first addition to the engine oil.
4. Chemicals improve the functionality of your engine, lubricate and clean even the smallest parts.

These are only the most important facts, and of course, there are many more, that you will discover as you use the additives regularly.

Types of oil additives

As you may have guessed, there are different types of additives, with different uses. These supplements are usually intended for a specific problem, but can also be combined, for various engine improvements.

There are supplements to improve engine viscosity. This means that they help the oil to function the same way, whether it is cold or hot outside. When heated, the viscosity of the oil changes, so the additive helps it to be constant no matter what happens inside or outside.

A popular type of additive is those that serve to lubricate engine parts, which protects them from wear. It also prevents oxidation of the parts where the oil penetrates less. This also helps to prevent corrosion and rust on the engine in the long run.

Some additives serve as a detergent to clean the engine. This removes all residues from the oil combustion.

Are there any bad additives?


A bad additive is almost non-existent. You can only make the wrong choice, which can have the opposite effect on the needs of your engine. Sometimes it is better to use supplements recommended by the car manufacturer. In general, it can be said that there are no bad additives, but they can be chosen incorrectly due to current poor evaluation.


Before adding the additive, change the oil. You should do this especially if the engine oil is really very old. Choose quality oil and additives that will complement each other.

Note that additives are not always necessary for the engine to work. This applies to new vehicles, which have an optimized mode of operation.

But if you have an older car, additives can help you get the most out of your engine. Consider using additives if the engine makes a strange sound, smells bad, or has a check engine light on. These are different signs that your engine needs an additive. The benefits are numerous, as the engine returns to optimal operating mode and extends the life of the vehicle itself.


In general, engine oil additives are not bad for your vehicle, but only if you use them in doses that are recommended. That’s why you need to find an effective supplement, with quality ingredients, but also compatible with your engine and oil. It is necessary to work functionally with different engines. This maximizes the positive effects of the additives, thus extending the life of the car.

However, if you think there is no need for additional additives, you are not obliged to use them. But do not forget about regular technical inspections in such cases. And that would be everything we have to say on this topic.
