Criteria Used in Evaluation of the Best Oil Additives

 

It’s important to us that you know how we picked and ranked all these oil additives. This wasn’t an arbitrary thing that we did, not at all! We made a list of the most important things that an oil additive has to fulfill in order to meet the top category. We applied the strict criteria and came out with the most accurate list. Here is a slight insight into our method:

Compatibility

For the engine oil additives to work, it has to be compatible with the engine you have. We couldn’t guess which type you need, but we could take into account the versatility of each of our 10 picks. The products that are compatible with more engine types are at the top of our list. The same applies to different oils. The most versatile ones deserve a better position as they are likely to work for most buyers!

Protection

Of course, this was a crucial factor in the evaluation. All these oil additives are designed for different purposes. In most cases, they all feature basic protection and then they offer a solution for just one major issue. The oil additives that can resolve a variety of problems are ranked at the top. This doesn’t mean that the other ones are bad. Not at all! Actually, you might find them more suitable for the engine issue your vehicle has. They are just not designed to resolve everything! You get now why we had to rank the most versatile ones at the top. They give you more options!

Cost and Value

As you can see for yourself, oil additives are quite pricey. They do last for a long time, that’s true, but you’ll still have to pay quite some to get them. We included some very cheap ones that are also super useful. These are rare finds! However, we ranked them and the pricey ones according to the value they provide for the money. Now, there was one more thing to consider. We took into account the size of the bottle! This is very important. Some of them look super cheap and then they come in a tiny bottle that doesn’t last. That’s why this factor was important for the evaluation as well. Also, we provided a short review of every product on the list. It contains all the information you need about the bottle size, cost, and value of our 10 picks for the best oil additives!

 

Other Factors To Consider

 

There are many things to consider before buying an oil additive, as you probably learned by now. We all want to make sure that we are using a quality product for the maintenance of our favorite vehicles. Now, to be sure that you’re making the right decision, you can follow the short list provided below. We spend hours thinking over the things that are important to consider. Finally, we made it through and made a list. It should help you pick the oil additive that meets your needs! Let’s start with checking the:

Engine Type

This is the first and most important thing you should do before you opt for a particular product! Check the type of engine on which you’ll be using the product and see if they’re compatible. If not, keep looking! You don’t want to pour the wrong type of liquid in your car. In most cases, nothing bad happens. You might see that it doesn’t work on your vehicle, and that’s it. However, this could sometimes damage the engine, so it’s not the thing to be played with!

Oil Type

The second most important thing is to consider the type of oil you’ll be using for the engine. Don’t skip this step! If you use two different oil additives that are not compatible, you can damage the engine big time. It’s the same when you picked the additive for the engine you have. Only now you’ll have to pick the one that’s compatible with the oil you’ll be using. Or you can buy the oil after the additive. The choice is all yours, just get the ones that work together!

Additive Type

Now, here’s the part when you decide on a certain type of motor oil additive. How should I do this, you may ask? It’s rather simple. Think about the issue you have with the engine. The solution lays in the product you’re about to buy. If your engine has problems with overheating, you should get the best protection against high temperatures. The same applies to all other problems! You can compromise with other features and choose them at your personal preferences. They are for regular maintenance. The first pick should be for the main issue you have with the engine!

Budget

Let’s be honest here, these products are not cheap. Sure, you can always find a cheap and effective additive, but it might not fulfill the factors listed above. Or it might not be suitable for the thing you need it for. Either way, if you’re on a limited budget, you’ll have to compromise. Consider your budget limitations before the purchase. Then review all the factors you already considered. We recommend adding a few bucks to get the better one. If you can do it, believe us, it’s worth it!

We can’t pick just one because they are all different and deal with different problems!
