The Best Oil Additives: Revive Your Vehicle's Engine Performance (2023)

Archoil AR9100 is an oil additive suitable for both petrol and diesel engines. What really makes it stand out is that it can fix the Powerstroke's cold start problems, which could save you a lot of money in the long run. What else? It can reduce engine noise, friction and vibration intensity.

The oil treatment is made of zinc; therefore, it is capable of reducing wear and tear on your engine parts. It also improves oil consumption and the performance of hydraulics, steering and transmission. The capacity of the bottle is 16 fluid ounces, which is enough for long-term use without the need for replacement.

The biggest drawback of the Archoil AR9100 is that it does not perform well when exposed to a hot environment. Even so, you can still use it comfortably if you live in places with cool or cold weather. Just don't store it in a cold garage during the winter, or you'll end up with a crust.

When you choose Liqui Moly Anti-Friction Oil Treatment, you get great value for the money you spend. This product is an engine oil additive that has been shown to be quite effective in reducing engine friction and overall noise. With regular use, the product helps the engine accelerate better and run more smoothly, extending its life. Besides being useful for automotive purposes, this oil additive is also suitable for machinery and tools.

The product is available in a 300 milliliter bottle, which means it is long-lasting and budget-friendly. A drop or two of this liquid can help. Even if you don't notice an improvement right away, the product will significantly extend the life of your car's engine and protect it in the long run.

Although some users have noticed a great improvement in the performance and noise of the car's engine, others have not found this product as useful. The fluid does not seem to show the final results on all vehicles. Also, some users do not like that the product turns the oil black and thickens the oil.

Here's another Liqui Moly additive worth considering: Liqui Moly Cera Tec Friction Modifier. This product is a little different from the previous one; it is actually made to balance with any type of commercial motor oil. This means you can travel long distances without having to worry about changing oil additives to work with a specific type of commercial motor oil. Once activated, the oil additive will remove any deposits that block the filter system.

It's rare to find an oil additive that won't compromise its quality in extremely cold or hot environments, but this product doesn't live up to that expectation. It even gets rid of irritating white smoke when starting the vehicle. A 300 milliliter bottle can be mixed with up to 5 liters of motor oil.

The texture of this Liqui Moly product is thick, which makes it difficult to put it in the oil filler. The smell is also unpleasant and could be repulsive. That said, it's still a solid option, especially for drivers with older cars.

Older cars with high mileage engines usually need something a little different than brand new vehicles. And if you drive an older model year vehicle, you'll want to take a close look at Lucas Oil Heavy-Duty Oil Stabilizer. It is a reliable product that has proven to be very useful for old engines. Extends oil life and reduces overall oil consumption, keeping the engine running for longer. The 100 percent petroleum product is designed to eliminate dry starts and reduce friction, which eliminates noise and extends engine life.

With this product, your vehicle will become quieter and run smoother. The formula is quite potent, so you only need a drop or two of this fluid to regularly maintain your car, truck and other vehicles. Also, the liquid does not change the viscosity of the oil, and protects cylinders and piston rings.

One of the disadvantages of this product comes from the fact that it is not the best option for new engines. Although it proved quite effective with old engines, it could be too sticky for new ones and stick dirt. Also, some users think it's a bit pricey, even if it comes in a 1-gallon bottle that lasts.

Sometimes it's best to spend more to get a high-quality, highly effective product — and that's the case with Motorkote Hyper Lubricant. This Motorkote lubricant is suitable for almost all synthetic and petroleum-based oils. Its main advantage is versatility, since the product works on both gas and diesel engines. It is recommended by the manufacturer and professional mechanics for all purposes in cars and machinery, so you can use it on cars, trucks, lawn mowers and other equipment. And while it's more expensive than many of the other options on our list, it can be a worthwhile investment if it suits your needs.

Motorkote lubricant is very effective in reducing friction and heat for better engine performance. It helps the engine run smoothly and quietly and prevents dry ignition, which ensures a more comfortable ride and a longer engine life. Also, the liquid is not too sticky and will not clog.

The main drawback of this product could be its price. A one-gallon bottle turns out to be quite expensive, although it lasts a long time. Also, some users have not noticed any real improvement in gas mileage, so the oil additive may not be suitable for all engine types.

Prolong Super Lubricants engine treatment contains an anti-friction formula that works on both diesel and gas engines. It is a strong yet safe product that works well on cars, motorcycles, trucks and machinery.

The product is easy to use, and results are seen almost immediately. The liquid interacts with metal surfaces to create a protective layer that reduces friction and heat. Furthermore, the engine accelerates better and runs more quietly, without noticeable noise. The product is also easy to use and safe for the vehicle.

One of the concerns about this product comes from the formula itself. The company seems to have changed it and it's not as dense as it was in the past. It could also spill out of the bottle if you are not careful enough when adding it to the vehicle. Another concern is the price because the liquid does not last long.

What makes Hot Shot's secret oil additive stand out is its powerful formula that cleans and maintains the engine. The product increases overall engine power, removes deposits, reduces friction and noise. In addition, it does not contain any harmful acids that could damage the engine, so your vehicle will be completely safe.

This oil additive is very effective in protecting engine parts and stabilizing the oil. You can use it on both diesel and gas engines. The product quickly removes deposits, improves mileage and lubricates the oil pump, rings, pistons, injectors and more. Results are seen almost immediately, resulting in more enjoyable rides.

Although very effective and reliable, this oil additive is not flawless. It seems to work better on diesel engines than gas engines. Although it significantly improves the overall performance of diesel engines, the noise reduction in gas engines is not as noticeable. Also, considering the product comes in a 32 ounce bottle, it is quite expensive.

Another high-quality product worth your attention is BG MOA Oil Supplement. It is a powerful fluid that protects and maintains the engine, improving its overall performance. By keeping engine components clean, it extends engine life and ensures a smoother ride.

The product is quite easy to use. All you have to do is add it at every oil change and you'll see your vehicle's performance improve in no time. You can even use it on equipment such as lawnmowers for regular maintenance.

What may be a drawback of this product is the fact that it works better with conventional oils than with synthetics, although in both cases it is quite useful. Also, it is not recommended for lubricating engine assemblies, nor is it suitable for brake oils.

The goal of REV-X High Performance Oil Additive is to increase horsepower, torque and efficiency. You can use this product in a variety of lubricating fluids, including engine oils and gear oils, as well as hydraulic, transfer case and manual transmission fluids. It comes in a 4-ounce bottle and does not contain harmful additives such as Teflon or acids.

REV-X increases the performance and service life of the lubricant. Machined components don't wear out as quickly and run smoothly. Users are having a lot of success using this product with the 6.0 liter Powerstroke engine. It fixes bad injectors, helps significantly with cold starts and can really bring your truck back to life.

However, it may take up to two oil changes to really see a difference. Also, there may be cheaper oil additives that do the same job. Some users complain that the product is overpriced.

Has your engine been through a lot of wear and tear? Consider adding Hyperlube Rislone Hy-per Lube oil additive to the mix along with the motor oil. This additive is more than just a performance enhancer - it's actually formulated as an extreme pressure lubricant, which means it can significantly improve your motor oil's cushioning and shock absorbing potential.

Mixing in this additive can lead to improvements such as less lifter and powertrain noise. It offers greater protection between oil changes, extending the life of your oil by as much as 50 percent or up to 7,500 miles. Compatible with all petroleum and synthetic oils, you will be able to use it in almost any vehicle.

But the benefits of this additive do not end there. Use a Hyperlube product and you'll also get better film strength, improved viscosity and less thermal breakdown. It can lower transmission and transmission temperatures and can restore some performance to older engines. It will even help seal piston rings and valve guides. It's comprehensive protection and enhancement that's hard to beat.
