What are Oil Additives? How do They Work?

Additives offer a way to enhance your motor oil without replacing it. Let’s touch on the basics before we go any further.

The oil circulating through your engine is the lifeblood of your vehicle. It keeps the vital internal mechanisms in the motor running smoothly.

It is first and foremost a lubricant. To power our vehicles, engines operate at high temperatures and under enormous pressure.

From the fuel pistons to the cylinders, everything is working in sync to keep the vehicle running. Keeping all these parts lubricated prevents them from wearing away or seizing up.

Oil also works alongside the coolant to stop your engine from overheating. By circulating, it carries heat away from parts that get extremely hot while in motion.

Lastly, it plays the role of cleaning out your engine’s system. It gathers grime and other debris, carrying it to the filter. This reduces the risk of these build-ups accumulating and causing trouble later on.

The Difference Between Oil Additives and Additives in Oil

There are all sorts of motor oils for sale these days. You can choose conventional types, or unconventional products, which are made from fully synthetic materials or synthetic oil blends.

You can also find specialty products, like high mileage oils for well-traveled or older vehicles. Regardless of the type, nearly all of these products contain additives.

Additives are compounds that boost the properties of motor oil. Certain compounds have targeted abilities—e.g., rust-inhibiting, antioxidants, etc. The quantity and type of additives vary from brand to brand.

As I’ve mentioned, most now contain some sort of additive. However, you can also purchase additional additives that are designed to be mixed with the oil already in your engine. Think of them as you would a health supplement.

They work alongside the additives already in your motor oil to further improve performance. They can also help compensate for whatever may be lacking in your current oil.

Let’s say you’re dealing with the symptoms of a dirty engine. It may idle roughly or misfire on occasion. Perhaps your current oil is low on detergents. Purchasing an additive with a high quantity of detergent could help your vehicle run more smoothly.

Additives can be manmade or natural substances—or a combination of both. These substances will sometimes undergo chemical processing, to increase their effectiveness.

Difference Between Fuel and Oil Additives?

Fuel additives are made to be added to fuel—gasoline, diesel, or biofuel. As with their oil counterparts, fuel additives enrich your car’s fuel. They can increase the octane rating of gasoline (for example, with the best octane boosters from our guide), fight corrosion, and promote lubrication.

These additives may share some similar ingredients with oil additives, but that’s it. Motor oil and fuel of any variety are distinct compounds. Respective additives are created to meet the needs of each.

Needless to say, you shouldn’t substitute one for the other. Any treatment intended for your fuel won’t do well in motor oil, and vice versa. You can avoid a costly visit to your mechanic by using the right variation.

What are the Benefits of Using Oil Additives?

We’ve already established that they have beneficial properties. It’s time to get familiar with all the advantages that using these additives can bring to your vehicle, while we take a look at the different types of oil additives.

Reduce Friction in Your Engine

Friction is unavoidable in engines. As it clocks up the miles, wear and tear will become more of a concern.

Certain additives protect the motor from friction damage. They can accomplish this through lubrication and film forming.

The more lubricated your oil is, the better. Lubricant-based additives keep it slick to ensure the mechanisms continue running at optimal capacity.

Other additives can form a film over metal. This film serves as a shield over the moving parts to protect them. In a quality oil additive, the film shouldn’t interfere with function.

An example of film-forming compounds is ionic liquids. These chemicals are absorbed into metal, creating a film on the surface. This film takes the brunt of the friction rather than the part itself.

Phosphorus and zinc are also additives that stave off wear. As with ionic liquids, they form a thin surface film over metals.

If your engine is already worn, avoiding further friction damage is essential. The motor in your vehicle is durable but not invincible.

If you want to keep your automobiles running for as long as you can, this involves preservation and care. Even newer vehicles can benefit from friction-reducing additives as a preventative measure.

Improve MPG and Fuel Economy

These additives can improve your miles-per-gallon (MPG) rating. With the right one, you can save on fuel costs.

It’s important to note that no magic chemical or compound that can conserve fuel. Rather, they help to economize fuel indirectly by reducing friction.

If your engine is poorly lubricated, more friction needs to be overcome to power it. Friction is a primary cause of unnecessary efficiency loss in most cars, especially older models.

Clean Your Engine of Deposits and Sludge

Other popular additives are those with detergent and antioxidant properties. These clear out everyday deposits that can accumulate internally, such as soot and road grime. They act as dispersants, attracting dirt particles and carrying them away.

These additives can also break down sludge, which may be hindering your vehicle’s performance. They inhibit debris from building up and reforming.

Even well-maintained engines can face problems. During the combustion process, acids are formed. High levels of these acids can cause corrosion and other nasty consequences.

Additives such as calcium carbonate work to neutralize these acids. Other compounds used in detergent additives include sodium and magnesium.

Extend Oil Lifespan

There’s a reason why we have to change the oil in our vehicles every so often. Remember that the environment inside your engine is harsh. Oil degrades over time, losing its effectiveness.

This is due to multiple factors. For example, exposure to extreme temperatures, either external or internal, results in degradation.

The same is true of the contaminants found in your engine. Don’t forget, oil accumulates dirt and debris of all sorts. It’s exposed to dust, soot, chemicals that can form, and more.

Unfortunately, not every last bit of contamination is removed by the oil filter. Leftover particles remain in the oil, contributing to deteriorating quality.

Additives can stretch the lifespan of your oil by combating these issues. As an example, polymers are often additional ingredients, due to their versatile abilities.

Polymers can change the density and temperature-resistance of oil. In turn, this can stretch the time between changes.

Of course, this doesn’t exclusively apply to polymer-based additives. Any additive that alters the property of the base (current) oil can improve its longevity.

Stop Leaks

As your engine seals age, they’re more likely to leak. Rubber can dry out, shrink, or perish over the years.

The formula of these additives may include conditioning agents that can moisten and rejuvenate dried out, brittle seals. Minor leaks can be stopped or prevented.

Enhance Overall Performance

Your engine can run under less-than-ideal circumstances. It’s running, but not necessarily as well as it should. Excess friction, sludge, and dirt can all impact performance.

Oil additives are likely to have a noticeable effect on how your vehicle runs. Loud, rough-sounding acceleration and idling can be quietened. Cars that have lost horsepower over the years could recuperate power.

Make Sure You Buy the Right One!

These compounds are not universal products. You can’t buy one at random and expect that it will work with any and all vehicles.

Choosing the best oil additive for your individual vehicle is important. Before you make your purchase, bear in mind the following:


Check that the additive you’re considering is compatible with your vehicle, and the oil you are already using.

You should know what type is in your car, whether it’s conventional, blended or synthetic. It’s important to double check that the additive you’re considering is suitable.

You are also aware of the specifics of your engine—or at least you should be. Is the product you are looking at suitable for gasoline or diesel? Can it be used to treat two-cycle or four-cycle motors—or both?

Make sure to think about how many vehicles you want to treat. If you have more than one, you may want to buy a product that’s multi-compatible. This way, you won’t have to buy numerous products to suit each vehicle.

The Purpose of Your Additive

Keep a mental list of what you’re looking to get out of one of these treatments. This is going to be unique to your vehicle’s condition.

Is protection from friction damage your primary concern? Or are you looking to clean your car’s internal works out thoroughly?

Select a product with the specific properties that you’re looking for. There’s no reason to pick any old brand when you can go for one that’s better suited to your vehicle and your needs.
