Best oil treatment for high mileage engines

If you are familiar with the working of an automotive engine, you must know that the engine and its internal component undergo tremendous amounts of temperature and pressure on a daily basis while they are functional. So, the performance of an engine degrades over time because of internal wear and tear and minimal damage to the internal parts.

If there is an excessive amount of friction between these parts, the effects are even more severe. You will also start noticing irregular sounds coming out of your engine that you hadn’t heard before. To avoid that, you will have to keep your engine maintained with the help of a decent oil additive. Before you buy one, make sure you check the following factors.

  • Friction and Temperature Resistance: It is quite difficult to determine which oil additive is perfect for your engine just by looking at its technical specifications and chemical qualities. You need to ensure that the oil you are buying can reduce the friction between the internal parts of your engine while offering a high-temperature resistance. Generally, oils made by premium brands have this quality.
  • Quantity: Apart from what oil additive you are buying, you also need to consider how much oil additive you are buying and whether it is sufficient for your work or not. Generally, it is recommended to get extra oil additives that are on the safe side. While you are applying the oil to the engine, there are chances of spillage and other forms of oil wastage. Even if not, you can store the extra oil for your next maintenance session.
  • Type of Package: The application method of the oil additive is also dependent upon its packaging type. While some oil additives arrive in a standard lidded container, some are offered with innovative packaging that surely helps at the time of application. Some great examples of that are tube-type packages and even standard containers with an extended neck design to make the application easier for everyone.

There are a lot of things to consider before you can decide which oil additive will offer you the best results and flawless engine performance. And it is certainly not easy to pick one since there are hundreds of different options present in the market from renowned as well as fresh brands. Therefore, we have already selected the best oil additives available in the market right now and listed all of those options right here. After that, we will discuss some major parameters of oil additives in our “Buying Guide” for the best oil additives.

Buying Guide For The Best Oil Additive

Professional drivers and automobile enthusiasts can definitely affirm the importance of regular engine maintenance procedures and their effect on the performance of the engine. One such activity is engine oil change which should not be missed or overlooked in any case. Even if you have previously changed the oil of your engine, you should still consider keeping some in reserve as you never know when you might need one.

While the engine is functional, it constantly bears increased temperatures and frictions, resulting in changes in its physical and chemical properties. Therefore, oil change is a recursive process and must be done once or twice within a year to keep your engine maintained. If you are not sure how to buy the right oil additive for your engine, check out our buying guide for the best oil additives given right here.

1. Chemical Properties

At the end of the day, an oil additive is nothing but a non-viscous liquid compound introduced into your engine to improve its performance and reduce common engine problems. Therefore, the overall results and performance of engine oil are solely dependent upon its chemical composition. There are a few elements like zinc or phosphorus that can certainly increase the effectiveness of the compound.

The zinc element is introduced in engine oils to increase the engine’s performance, making it an important factor for older and lesser-efficient engines. On the other hand, phosphorus is used in the chemical compound to ensure low friction levels while the engine is functioning. Apart from that, there are a lot of other chemicals that are included in engine oil to increase its effectiveness. If you want the best performance, we will recommend going with a popular option that has already been tried by hundreds of other users.

2. Range of Effects

While you are buying an oil additive for your engine, you should try to find the effectiveness of the product as well as check the promised results from the brand before making a choice. It is possible that certain engine oil is designed to serve a dedicated purpose, making it a bad choice for your bike or car.

There are a bunch of results that should be expected from oil additives such as frictional reduction, deposit removal, lubrication, increase in engine performance, corrosion prevention, and much more. As you can imagine, it would be overkill to expect all of these results from one product as there is a selection of results promised by the manufacturer from the oil additive. Still, it is a great choice if the oil additive manages to offer multiple benefits without needing any extra additive for your engine. Such options are diverse in nature and offer the best value for the investment.

3. Fuel Efficiency

If you don’t already know, oil additives also have a significant impact on the fuel efficiency of the engine. When the engine is new, it offers a pretty good mileage as its fuel consumption level is comparatively lower. But as the engine gets older, there are increased levels of friction and other internal problems that are generated over time. So naturally, the force required to move the crank increases, causing an increase in the fuel consumption level.

An oil additive comes into play here as it reduces the friction levels of the engine, reducing its fuel requirements. With the right oil additive, your engine will run smoother than ever, offering a noticeable increase in fuel efficiency. So even if you end up with a premium-grade oil additive for your engine, it can be a cost-effective option in the long run if it promises an increase in fuel efficiency, saving a lot of expenses later on.

4. Quantity

Lastly, we will suggest checking out how much oil additive you need before you make your purchase. While some users might be looking for a compact oil additive pack to maintain the engine of a smaller vehicle like a bike, others might be interested in the maintenance of a truck or RV, requiring a significantly larger oil additive canister.

Therefore, we have mentioned the quantity of oil additive you will receive in the package right along with our picks. This will definitely make the selection procedure easier for you as you can focus on products that are suitable for your needs.

Some oil additives are also offered in a pack of multiple units. It can also be a better choice if you want extra oil for future maintenance needs. Oil additives have a pretty long shelf life, especially if you don’t break the seal of the package. So, you can simply store the oil additives on a shelf for as long as you want, or until you need to change the oil of your engine again.

Frequently Asked Questions

1. Do oil additives affect oil pressure?

Ans: Oil pressure is also an important factor for the proper working of the engine. If the engine status lights in your car are showing signs of low engine oil pressure, you can put an oil additive in the engine and fix that. But, keep in mind that this is a temporary measure since an oil additive does not increase the oil pressure permanently. Once the oil additive is adjusted in the engine, you may notice low oil pressure signs again. So, it is better to visit a mechanic to get your engine checked out.

2. Can oil additives have a bad effect on an engine’s performance?

Ans: Oil additives are designed for the sole purpose of increasing the performance of an engine and preventing problems like friction and corrosion on the inside. Therefore, oil additives shall not have a bad effect on your engine’s performance. But with that being said, you also need to ensure that you are buying the right oil additive for the oil used in your engine for things to work out the way they are supposed to. While most engine oils are universal and work with most oil additives, it is safer to double-check the compatibility before you place your order.

3. Is it fine if I mix different oil additives together?

Ans: We will strongly recommend you do not mix 2 or more different oil additives together to use with your engine. As different engine oil additives are made up of different chemical compositions, nothing good can come out of mixing 2 different oil additives. With an ever slim chance of an increase in performance, there is a strong possibility of one or both oil additives actually degrading the performance of your engine, far be it from any sort of upgrade.

Conclusion:

Oil additives are special oil compounds designed to be poured into the engine to help with its internal cleaning and maintenance. The basic benefits of an oil additive include cleaning the debris, improving oil pressure, and increasing the overall fuel efficiency of the engine. So, you should carefully choose which oil additive you are putting in your engine and whether it is the right pick for your engine or not. Generally, the choice of the oil additive depends upon a few key factors like its performance, quantity, compatibility with the engine oil, and range of use. If you want to know more about these factors, take a look at our buying guide for the best oil additives present on this list. We will also offer some handy recommendations right here so that you can choose the oil additive without a second thought.
