A Guide To Buying Engine Oil Additives

In order to choose the best product, it is important to understand the common types of chemical compounds in oil additives. Before you make a purchase, check the chemical compounds of the engine oil additives. It will help you know which option will be the best for your car.

Zinc: If your oil additive consists of zinc, then it is available as a performance booster. Zinc is an ideal chemical compound for engine oil additives. It works wonders for older models, i.e. the traditional cars. Make sure you check the recommended amount of zinc usage and do not exceed the limit.

Phosphorus: Phosphorus and Zinc happen to be the two most common oil additives found in the engine. Basically, Phosphorus is used to enhance the vehicle’s performance by preventing unnecessary wear and tear.

Now, this leads us to an important question “how can the chemical compounds found in the oil additives benefit you”? Here is how oil additives can improve the performance of your vehicle.

Reduces Friction

Interactions between the metal components in your car engine can lead to deterioration. By reducing the friction between these materials, the oil additive can extend the life of the important metal components running in your car’s engine. Besides, it prevents wear and tear from metal-to-metal friction.

Increase MPG

Now that you are upgrading the engine oil, you will notice a 2 MPG increase as soon as the oil changes. This reduces the unnecessary pressure in your motor and saves you hundreds of bucks in the long run.

Rust Inhibitors

Not only do you need to protect your engine from chipping away due to friction, but it is equally important to keep your engine components from corrosion. Ensure a smooth and comfortable drive and extend the durability of your engine with oil additives.

Remove Impurities

Some additives are known for their detergent properties that help clean the metal components. They unclog all the dirt and debris stuck between these running parts and prevent friction. Now, you don’t have to worry about the impact of unclean components on your engine’s performance.

Control Too Much Smoke

Does your car produce excessive black smoke? Well, oil additives can be your ideal solution to the thick and black smoke. Basically, the excess amount of smoke is produced because of the engine oil loss. As a result, the thick black smoke is released from the engine’s exhaust pipe. The additives not only prevent the smoke, but it can help control the unnecessary engine noise.

Control Leakage

Oil leakage is one of the most common issues in engine oil. The good news is you don’t need to take your car to the automobile servicing store frequently. With the right oil additives, your car will not suffer oil leakage. Usually, car owners get their engine oil replaced if it is leaking. However, the additives are designed to repair the minor scratches and gaps that may cause leakage.

Common Types Of Oil Additives

Detergents

As the name implies, the main purpose of using detergent oil additives is to remove all sorts of impurities and dirt collected on the engine components. Since detergents are mostly alkaline, they can control the acid levels in the engine. This protects the engine from debris, dirt, dust, and other accumulated particles.

Antioxidants

Antioxidant oil additives are used to decelerate the oxidation. It builds a strong layer that avoids corrosion and keeps your engine healthy and active for years. Basically, oxidation leads to corrosion and premature wear and tear of the components around your engine oil. If you choose the additive oils rich in antioxidants, then you can rest assured that your engine oil will last for years without showing any sign of deterioration.

Friction Modifiers

Metal components in your engine are prone to friction. A friction modifier is designed specifically to control the friction level between metal components. Not only does it protect the components from chipping away, but friction modifiers save your fuel economy and improve the durability of your engine oil. Most engine oil additives available on the market feature friction modifiers.

Anti-foaming Agent

Manufacturers have started to design oil additives containing an anti-foaming formula. Such solutions consist of strong chemicals that prevent bubbles and foam in your car engine oil. Foam and air bubbles in the oil can cause significant damage to the engine oil as well as the running components in the engine. If the bubbles do not burst, they will accelerate oxidation that can result in corrosion.  Car owners do not need to buy a solution rich in anti-foaming agents. Only a small concentration of this formula will suffice.

Viscosity Modifiers

Your engine oil tends to lose its thickness and consistency when it is exposed to extremely high temperatures. As a result, the oil gets as thin as water. To avoid this issue, viscosity modifiers can be mixed with your car additive oil. These additives can maintain the oil fluidity and keep the engine oil from getting thinner over time. Moreover, it improves the fuel economy and prevents premature wear. Before you make a purchase, check if the oil additive contains viscosity modifiers.

Tips For Selecting The Best Type Of Oil Additive

Oil additives blend well with the engine oil and improve your vehicle’s overall performance. It reduces wear, promotes smooth driving, eliminates impurities from the components in the engine, and prevents oxidation and corrosion. If you would like to upgrade your vehicle and improve its efficiency, then oil additives should be your first and cheapest investment. If you are not certain about the best quality oil additives on the market, you have come to the right place. In this post, we have mentioned a few important factors you need to take into consideration when buying engine oil additives.

Climate Adaptability

Despite being designed to resist almost all weather conditions, only a few units can withstand freezing temperatures. Some oil additives cannot handle the high temperature. There is a good chance they will lose their consistency if exposed to extreme temperatures. The best model is the one that can withstand almost all temperatures efficiently. Climate adaptability is especially important for those who live in places that receive either extremely hot or below-freezing temperatures.

Compatibility

It is important to note that only a few oil additives are compatible with all types of vehicles and engine oil. Most will be compatible with synthetic engine oil and specific types of engines only. To ascertain the best and most suitable oil additives for your vehicle, take a look at your car manual. The manual will also tell you the specific chemicals that must be avoided in the car engines. Of course, you have many options that are compatible with all types of car engines.

Chemicals

As mentioned above in the article, most brands add zinc and phosphorus to oil additives. Zinc is especially recommended for older vehicles since it enhances engine performance and extends its life. Phosphorus, on the other hand, can control metal-to-metal friction. You should look for a model that contains both zinc and phosphorus.

EPA Certification

Nowadays, both consumers and manufacturers are shifting to eco-friendly products. So, it makes sense to choose an eco-friendly oil additive that could reduce emissions. Such units will also be EPA-certified. Since oil additives are known for improving the fuel economy, they can reduce emissions. However, do not trust the manufacturer’s word. Check if the product is EPA-certified. An EPA certification indicates that the formula does not contain chemicals.
