Top 10 Best Oil Additives For All Time Top 10 Best Oil Additives For 2020/Oil additives are chemical compounds that improve the lubricant performance of base oil (or oil “base stock”). The manufacturer of many different oils can utilize the same base stock for each formulation and can choose different additives for each specific application. Additives comprise up to 5% by weight of some oils. Nearly all commercial motor oils contain additives, whether the oils are synthetic or petroleum-based. Essentially, only the American Petroleum Institute (API) Service SA motor oils have no additives, and they are therefore incapable of protecting modern engines. If you want, your engine to perform likes the Champ it’s meant to be then you should think of using oil additives. Yes, the regular oil will work fine as long as you stick to the manufacturer’s recommendation. This includes correct grade, right volume, and timely changes. However, as you probably know, the oil will disintegrate over time. It will become thinner and lighter and will break down due to contaminants. What this means is that the lubricating characteristics will be undermined. This leads to increased friction, which in turn causes more tear & wear. Besides, there is a higher risk of engine damage. That’s why we would like to introduce you to the best oil additives. Best Oil Additives For All Time The Best Oil Additive Liqui Moly Cera Tec Friction Modifier. Lucas Heavy Duty Oil Stabilizer.

Keep in mind that rust is one of the leading causes of deterioration in older engines. Improve engine performance – Usually, when an engine is burning too much oil, it will slow down. Additionally, when the oil in your car’s engine is too runny, like water, it will distort the performance of your engine. However, oil additives contain oil stabilizer elements that help thicken the oil and enhance engine performance. Clean the engine – There are some engine oil additives that have detergent characteristics. This would be helpful to unclog impurities that are stuck between the engine parts, reducing the extreme friction. Alternatively, oil additives can also be used to regulate temperature. Stop excessive smoke – If you’re driving a car that coughs too much thick, black smoke like it’s being strangled, oil additives may solve the problem. The oil additive acts by reducing the engine oil loss that causes excess smoke to blow out of your exhaust pipe. It also reduces engine noise. Prevent oil leakage – A top-quality engine oil additive should be able to seal small scratches and micro cracks to stop oil leakage. In the long run, this could save you a lot of money that would have been used to constantly replace the leaking oil. Types of Oil Additives Antioxidants – Oxidation causes engine parts to deteriorate when exposed to oxygen. Hence, antioxidant oil additives do the exact opposite by acting like a protective layer to slow down the oxidation process and prevent corrosion of the engine parts. Also, such types of oil additives are capable of prolonging the lifespan of the engine oil. Detergents – The objective of detergent oil additives is to get rid of impurities accumulating in the engine components. Moreover, detergents are alkaline in nature, and they’re used to neutralize the acidity level of the engine oil and avoid unwanted deposits that would otherwise form when exposed to high temperatures. Viscosity Modifiers – When blended with regular oil, viscosity modifiers play a role to prevent the oil from becoming thinner or watery after exposure to high temperatures. Alternatively, viscosity modifiers improve oil fluidity at low temperatures, which helps to boost fuel economy and reduce wear. Most top-rated oil additives that are sold contain viscosity modifying elements. Friction Modifiers – A friction modifier serves the purpose of decreasing the friction between metal surfaces in the engine. In retrospect, friction-reducing engine treatment indirectly enhances fuel economy and could also be used as an anti-wear agent. Most synthetic oil additives that you can find on the market will typically include anti-friction formula. Anti-Foaming Agents – Anti-foaming oil additive contains chemicals that inhibit foam and air bubbles in the engine oil. Otherwise, if the foam bubbles don’t burst, they would speed up the oxidation process, which would ultimately lead to corrosion. In most cases, you will need a very low concentration of anti-foaming agent to get the job done. How Do Oil Additives Works There are many different engine oil additives available, working in a range of ways: Anti-oxidants – These stop oxygen from reacting with component materials, reducing corrosion and sludge formation. Anti-wear agents – Anti-wear agents attach to metal surfaces and stop metal parts from wearing against one another. Usually dormant, they react when metal surfaces touch, forming a soapy film that reduces friction. Extreme pressure additives – Similar to anti-wear agents, extreme pressure additives react with component metals to create a film that stops adhesive wear. Activated by high loads and contact temperatures, they are a common fixture of gear oils. Viscosity index modifiers – These stop oil from thinning out at higher engine temperatures. Made from polymers, they become larger as they heat up and thicken oil, before shrinking in size as conditions cool down, ensuring viscosity at a wide temperature range. Anti-foaming agents – These chemicals have low interfacial tension, meaning they can enter the walls of bubbles, dilute, and split them. As well as tackling foaming, they can also reduce oxidation as they remove the presence of air. Detergents – Detergents clean the engine of deposits and sludge, as well as counteracting any acids that form within the engine and oil. They are the foundation of the oil’s alkalinity, noted by the oil’s base number. Friction modifiers – Chemicals that lower the friction between engine components, Friction modifiers are typically used in transmission systems and help improve fuel economy, increase component lifetimes, and reduce deposit formation. Pour point depressants – An oil’s pour point refers to the lowest temperature at which it stays fluid. Pour point depressants allow oils to flow at lower temperatures, reducing the ability of wax crystals to form large, solid structures. Dispersants – Dispersants stop soot particles from forming large deposits within engine oils. Comprising a polar particle that seeks out soot and an oil-soluble tail, they blanket pieces of soot and stop them from sticking together or to components, spacing them out within the oil, until the deposits are removed during the next oil change. Emulsifiers – Used in fluids combining water and oil such as metalworking fluids, emulsifiers are chemicals that stop oils and water from separating by binding the two together. Demulsifiers – Demulsifiers change the interfacial tension of lubricants to stop the formation of water-oil solutions. They are used in applications where there is a large amount of water or steam present during operations. Tackifiers – Tackifiers stop lubricants from being propelled off components as they move – particularly rotational movement. They are usually used in the most viscous oils Biocides – Biocides stop bacteria from growing within lubricants, keeping them clean from contamination and safeguarding their performance. Guide to Buying the Best Oil Additives The opinion on oil additives depends on the person you ask. Though there are some that strongly advocate the products others are more reserved. We encourage you to form your own opinion! As a result, we have put together this buyer’s guide to help explain what you can expect to get with the top oil additives on the market. Understand the Types of Oil Additives There are different types of oil additives. You should get to know what type before settling on a specific product. Complete Engine Treatment – The oil additive prevents friction. It forms a protective barrier around engine parts to eliminate excess heat. Engine Break-In Oil Additive – The additive is combined with engine oil to protect the camshaft lifters in your vehicle. It can also lubricate the valve train. Engine Oil Stop Leak – The type of oil additive mainly stops leaks in engines by sealing the part that is causing the leak. Heavy Duty Oil Stabilizer – The oil additive mainly reduces friction. It enhances the lubrication inside the engine to make it run smoother. High Mileage Oil Stabilizer – As the name suggests, it protects the engine against wear and tears on older vehicles. Learn about the Chemicals in the Additive There are a couple of chemicals that are essential to a good oil additive for your car engine: Zinc – Zinc in oil additives acts as a performance booster. It mostly benefits older engines. Phosphorous – Phosphorus limits metal-to-metal friction in engines. The chemical prolongs the life of the engine. The best oil additives are generally blended with zinc and/or phosphorous. EPA Certification – Some oil additives reduce harmful emissions. Basically, when fuel economy has improved the level of emissions is reduced. Oil additives that are known to reduce harmful emissions have EPA certification. It also indicates that the oil additive doesn’t contain any harmful substances. There is an alternative called PEA certification that indicates the same eco-friendliness. So, if you want to make an environmentally-friendly purchase, refer to the EPA and/or PEA certification. Engine Model – The product should explain on the label what it is designed to support. Some additives are designed for gas, while others are diesel. Some can assist with both types of engines. It is very important to understand if the additive is compatible with your make and model. Check the user’s manual of your vehicle to find out what type of engine it has to make sure the oil additive is compatible. Double Check to Make Sure the Oil Additive is Effective – Companies that produce oil additives may guarantee it works for all types of engines. However, your user manual is a better source of verification compared to the promise from the manufacturer or label on the bottle. The user manual will indicate what type of oil additives you can use for the engine. It may even list chemicals to avoid in order to narrow down your search. Where You Live Matters – Some oil additives can’t withstand certain conditions. Cold weather is notoriously hard on oil and additives. However, most are able to withstand hot temperatures, even extreme heat. So if you live in a very cold place you may find some products are ineffective, or even damaging to the engine. Final Thoughts Like many people, you probably overlook the value of oil additives. And because of this, you stick to the one the manufacturer recommends. While this is okay, you can make it even better by also using an additive. The compound will not affect the existing oil in any way. In fact, it will make it better in regards to viscosity, durability, heat dissipation, resistance to contaminants, and other things. To help you pick the best, we evaluated the popular types and managed to distinguish the very best from the rest. By using one of these best oil additives that were mentioned in the review, there is no doubt that your engine will perform better, have lower emissions, and will last a long time.
