If You are Looking for Best Oil Additive, This Page is for You. 2018’s Top 10 is Here!


According to the advertising, the oil additives are truly a magic potion. There’s not a problem on the Earth that can’t be solved by an oil additive, according to them — just buy an additive, use it and you’ll get 200% improved performance.

Well, it’s not that simple. Of course, a good additive can really improve the performance, but if you choose a wrong one, it may lead to certain problems with the engine of your car — so it’s necessary to be very careful with this choice.

There are many types of oil additives, which subdivides into even more sub-types. But basically, you can say that there are two main types: oil stabilizers (they are also called viscosity modifiers) and extreme wear additives.

The thing is, the viscosity of the oil (just as of any other liquid) changes when the temperature is high. The worse the viscosity, the more energy is spent by the engine to move the crankshaft.

Oil stabilizers fix this problem. With them, the oil lasts longer and the mileage is improved, so such additives are truly a gift to your car, especially if it’s an old car. The thing is, old engines need certain chemical compounds, and many additives contain these compounds.

I’m talking about zinc and phosphorus (well, technically it’s not just zinc, it’s zincdialkyl-dithiophosphate, but I’ll use the short title). For old engines, zinc is a necessary part of the oil — without it, there is no anti-friction barrier, and it’s a real threat.

That’s why you can use the oil with high levels of zinc or add the oil additives, which will not only improve the performance but also prolong the life of the engine. But of course, it’s not about old cars only.

New engines also need additives. Friction modifiers reduce the friction (well, it makes sense) and it’s a perfect way to increase mileage. Antiwear oil additives protect the metal parts of the engine. Detergents help to get rid of sludge in the engine.

Oil additives are very important, and it doesn’t matter if you have a 2017 Chevrolet Captiva or 1969 Camaro with 350 engine. But what does matter is to choose the right additive — and that’s exactly what I can help you with.

But at first, let’s continue talking about the additives. Are they really as good as the ads say they are?

Well, they are. At least some of them. The oil additives do really reduce friction and coat the parts of the engine in order to prevent a corrosion. It means that the majority of the additives do really protect your engine and extend its life.

Some additive contain detergents (agents with cleaning properties) — such additives clean the metal parts, and it extends the life of the engine, too. Viscosity modifiers improve the oil performance under the high pressure and prevent the cold-weather starting issues.

Another important thing you have to know is that additive won’t help if your engine oil is bad. These two work together and complement each other, so if the quality of the oil is low, an addictive wouldn’t help. Even the best and the most expensive one.

But if you have a good oil (and if everything is fine with the engine), a decent oil additive will improve the performance and make the engine last longer. Let’s begin.

The only thing left to do now is to choose the best oil additive:

Let’s begin.

1. Genuine Ford Fluid XL-3

Quality85%
Reliability80%
Practicality83%
Price85%

A 4 oz bottle of the best oil additive. I’m not exaggerating — this additive is manufactured by Ford, and it’s an excellent product. If you have Ford, you can stop reading right now, because it’s definitely the best choice for your vehicle.

For all the others — this is a perfect friction modifier additive which reduces chatter on differentials. With this additive your vehicle will work quieter, the engine will last longer and the transmission will not skip even if it already skips a gear now.

The only problem is its smell. It smells terrible (I believe that hydrocarbon is the reason), so be careful and don’t spill a drop. However, it’s the only disadvantage of this product, so if you are looking for a very good and very cheap additive, this one will work well.

 

 

2. Liqui Moly 2009

Quality84%
Reliability79%
Practicality83%
Price85%

It’s an anti-friction additive. It’s made in Germany, and it would work well both for vehicles and for industrial tools. Liqui Moly 2009 reduces the friction perfectly, so with this additive, your car will not only sound better but perform better, too.

The users say that the acceleration becomes smoother, the sound becomes quieter and the friction is reduced perfectly. I can’t say that it’s the best oil additive for older engines, but it’s very close to this title.

It’s basically one of the best friction reducers at the market, so you will need definitely not be disappointed with it.

 

 

3. Sea Foam sf-16

Quality80%
Reliability75%
Practicality76%
Price90%

This additive can be used both as a fuel and as an oil additive. It means that you can add it both to the oil and to the fuel tank, and it will work well in all cases.

Sea Foam SF-16 helps to clean the engine, so it would be really wise to use it in two cases: if you are going to change the oil and if the engine runs rough. This additive doesn’t improve performance, but, well, cleaning the engine is a very important procedure, too!

I recommend using it every 4-5 thousand miles, but this advice works for some vehicles, not for all of them. You can consult with your local mechanic in order to make exactly the best choice for your car.
 

 

4. XL Nanolube Engine Oil Additive

Quality89%
Reliability90%
Practicality85%
Price89%

Unlike the previous addictive, this one doesn’t just clean the engine — it’s multifunctional. All you need to do is to mix the XL Nanolube with the oil.

After that, it will start doing its job. Nanolube prevents the burning of the engine oil and thus extends the life of your engine (because the oil burning is the most common reason of the problems with the old engines).

But I’ve said that it’s a multifunctional additive, and it’s true. It also improves the performance (HP, torque), and improves the fuel consumption — sounds great, doesn’t it?

But it’s not just words. According to the reviews and feedbacks, this additive is a true magic, and it does really improve the horsepower/torque without making a fuel mileage worse. I recommend trying y this one, with no doubts.
 

 

5. Ai Innovations LUC10002 Lucas

Quality90%
Reliability87%
Practicality87%
Price84%

I can’t say too much about this one because it’s another perfect example of a good oil additive. Have you heard anything about the Lucas Oil Products?

I bet you have because it’s one of the most popular oil and additives manufacturers in the world. I’m talking about this because this additive is a very good example that can show you why people love it.

So, this additive must be mixed with an oil in order to increase its life and to get rid of oil burnings. Sounds quite simple, but that’s how the LUC100002 really works.

Add about 20% of this additive and 80% of the oil and you’ll be happy with it. According to the reviews, with this additive you’ll get no oil losses even if your engine is really old.

Be careful and don’t use it as a fuel additive (add it to the oil only). In this case, you’ll be really satisfied with this one.
 

 

6. STP High Mileage Oil Treatment

Quality74%
Reliability70%
Practicality71%
Price90%

The only function of this additive is reducing the oil consumption and preventing oil leaks — and what I can say is that it works perfectly.

You shouldn’t expect this STP product to help with engine smoking, with horsepower or with torque. However, if you have any problems with the oil consumption (and if you want to reduce it), this is the best option possible.
 

 

7. Red Line 81403 Break-In Oil

Quality80%
Reliability83%
Practicality82%
Price88%

NOTE: This additive is very good for the old cars, but works much worse if you have the catalytic converter inside of your car.

It’s an additive, that wouldn’t make your car run faster. It’s a break-in oil, which means you will not find a better product if you have a new (or rebuilt) engine. In this case, you have to use it in order to protect the camshaft and the new engine itself.
 

 

8. REV-X Stiction Fix Oil Treatment

Quality84%
Reliability85%
Practicality85%
Price80%

The main idea of this additive is stiction (static friction, often happens to the diesel injector engines) fixing. However, it can be used with any other engine.

Rev-X oil treatment also increases the HP and torque of your engine. You can use it even if you don’t have any problems with the engine, but if it works rough, that’s probably the most necessary thing to buy, because replacing the injector would cost you much more.
 

 

9. Archoil AR9100 Oil Additive

Quality90%
Reliability89%
Practicality85%
Price79%

Do you want to prolong the life of your engine? Do you need to reduce the noise and vibration? In both these cases, you’ll get what you need with this additive by Archoil.

It’s perfect for reducing the friction, it helps with misses and, what I like most, it does really reduce the noise, so you will hear the changes with your own ears

And of course, you can use this additive for any engine. Diesel, gasoline — it doesn’t matter.
 

 

10. Liqui Moly 20002 Friction Modifier

Quality93%
Reliability92%
Practicality90%
Price75%

It’s another perfect solution for those who are looking for the engine’s performance to improve. If you are such a person, this Liqui Moly additive is exactly what you need.

This product contains HBN and MOS2 — chemical compounds, which make the engine temperature lower and don’t let it overheat. It means that you can forget about the temperature problems with Liqui Moly 20002 — but of course, that’s not all.

Improved mileage, reduced chatter — I don’t see any reasons why you should miss this additive. It contains very small ceramic particles which fill the scratches inside your engine, so it will last longer.

Be careful: sometimes it may take up to 1 week for this additive to start working, so don’t disappoint during the first 5-7 days.
 

 
As you’ve probably noticed, there are literally dozens of additives types — some of them are good for performance, some — for extending engine life, the others — for other purposes.

The thing is, you have to determine your goals at first — for example, if you want to get rid of stictions, REV-X product would be the best choice; if you want to improve the horsepower, XL Nanolube and STP additives are what you need.

Choose the one that fits your purposes and I’m sure you will not be disappointed with it!
