Anyone with a basic understanding of motors knows that oil is an essential part of their operation. It’s extremely important that you check your oil levels often and make sure there is enough oil flowing through your engine. 

Maintaining the appropriate level of oil in your engine will help it to function properly. However, using an oil additive might be able to enhance the abilities of your oil and boost the overall performance of your engine. Read on to learn more in this article of shine armor blog!

What Does Motor Oil Do For Your Engine? 

Oil is the lifeblood of your engine. Without oil, your engine won’t be able to last longer than a few seconds without experiencing permanent damage. There are a few responsibilities for motor oil, but the main one is to lubricate the various moving parts of your engine. 

The crankshaft component of your engine is where the pistons will move vertically to create the energy needed to move your car. Motor oil primarily stays in this area in order to lubricate all these moving parts and keep them gliding smoothly during their rotations. 

Since these moving parts are pumping at tremendous speeds, they can create a lot of friction and get very hot in the process. Oil is used to limit this friction and keep the engine as cool as possible. 

Oil also helps to prevent these parts from encountering oxidation, rust, or corrosion and removes potential contaminants that might cause sludge to build up. Most base oils are satisfactory at performing these essential tasks, but using an oil additive can really make a difference.

What Are Oil Additives?

Motor oil is a perfectly acceptable lubricant that can help keep your engine running smoothly and performing efficiently. The problem is that motor oil tends to break down and lose its effectiveness as it travels through your engine. That’s where the idea of using oil additives comes into it. 

Oil additives are different chemical compounds that are added into motor oil in order to help it perform a little bit better and last a little bit longer.

There are essentially three functions for oil additives:

  • Enhance the existing properties of the oil by further helping prevent corrosion, foaming, and buildups.
  • Reduce undesirable properties of the oil by maintaining its viscosity for longer and improving its pour point.
  • Provide additional properties to the oil, such as detergents to help keep the engine clean or absorbents to help plug leaks. 

There are so many benefits to using oil additives that most companies who manufacture motor oil have started to include them in the process. Whether the oil is fully synthetic or petroleum-based, there’s a very likely chance an additive was included when it was being made. 

In fact, most oils sold to the public include between 10 and 30 percent oil additives. Be sure to check the label the next time that you are buying motor oil so you can make sure you’re getting the right kind of additives for your engine.

What Are the Different Types Of Oil Additives? 

The phrase oil additive might sound like a generalized term, but not all additives are the same. The specific benefits of using specialized chemical compounds can be wildly different. None of these additives will do your engine any harm, but it’s just a question of using the right additive to meet your needs. 

There are several different types of oil additives available, including:


Different solvents are included in these oil additives in order to find and plug any leaks. The gaskets and seals inside your engine are constantly under pressure. Over time, they can begin to deteriorate, which results in leaks. Absorbent-based oil additives will find these gaps or cracks in your gaskets and create a makeshift seal.


Air bubbles can start to develop in your oil over time that create a foaming effect. When oil starts to foam it can result in overheating, oxidation, and misrepresent your oil levels during checks. Anti-foam additives aim to limit air bubbles from forming and prevent foaming.


When motor oil comes into contact with oxygen, it can create acids that result in oxidation. As a result, the oil can often become thicker and create a sludge that gums up your engine. It might also lead to corrosion developing on metal parts that come into contact with the oil. Anti-oxidant oil additives help prevent oxidation from taking place in the oil.


Acids, sludge, grease, and grime can slowly build up in your engine over time. Using an oil additive with detergents added in can help to break down these buildups and prevent them from forming in the future.


Foreign substances and other harmful particles can get caught up in your engine. Especially if you aren't regularly cleaning your engine bay as often as you should. Dispersants help to break apart these contaminants that might get stuck in your oil and prevent them from building up and creating clogs.

Friction Modifier

There is a lot of metal-on-metal contact happening at incredible speeds inside your engine. Your oil can only be in so many places at one time, and sometimes these moving parts are left without oil for a split second or two. Friction modifiers are designed to leave behind a protective film that coats these moving parts and limits the amount of friction they endure.

Pour Point Depressant

The term pour point is used to measure the lowest temperature that oil will flow. When the temperature of the oil is too low, it can cause wax crystals to develop. This will reduce the oil's fluidity. It will take longer for your oil to work its way through your engine and can lead to excess wear and tear in the meantime.

This is especially a problem during startups in cold weather. Oil additives with pour point depressants will help prevent wax crystals from forming and keep the oil in a liquid state.

Viscosity Modifier

The viscosity (thickness) of your oil slowly decreases over time due to natural decomposition and high temperatures. As oil gets thinner, it becomes less effective at lubricating your engine and dispersing heat. Viscosity modifiers help to keep the overall thickness of the oil staple for a longer period of time. 

Why Should You Use An Aftermarket Oil Additive?

The oil currently flowing through your engine almost certainly contains additives. These additives are included to provide a basic level of protection for your engine. Standard oil additives are perfectly serviceable and will help your engine function normally. 

On the other hand, aftermarket oil additives are specifically formulated to help boost the overall performance of your engine. The goal of aftermarket additives is to take your oil's performance to the next level.

Using an aftermarket oil additive can provide the following benefits:

  • Better gas mileage. Oil additives can help your engine operate more efficiently by reducing the overall friction generated by the various moving parts. Less friction and resistance will help reduce the total unit of fuel needed to create a complete rotation meaning better fuel efficiency and more horsepower.
  • Extends the effectiveness of oil. Motor oil will naturally break down over time and will start to lose its effectiveness after several thousand miles of intense heat. That’s why you should be changing your oil every 3,000 miles or so.
    Using an additive will help keep your oil functioning properly as you get closer to your change date. It will help limit the damage that might be occurring as the oil has lost its effectiveness. 
  • Prevents oxidation. When air bubbles start to develop in your oil, it can lead to a lot of problems. The oil can lose its ability to function properly and might cause rust damage to the key parts of your engine. Additives help prevent these bubbles and keep the oil flowing smoothly.
