Choosing an excellent engine additive requires you to be intentional about performance. You must understand what elements to consider in the process, as this assures you of value for your money. Here are a few things to check.


Thick engine additives are often an excellent choice for most engines. Yet, you need to consider the size of your engine tubes and openings before you buy one. It would be best to consider more viscous additives if your engine has wider openings. In contrast, thinner engine additives work best with thin engine tubes.

Additive Ingredients

The effectiveness of your chosen engine additive depends on its ingredients. These ingredients help boost the existing base oil properties, suppress undesirable base oil properties, and add new properties to the commercial oil. Ensure that your oil additive features antioxidants, corrosion inhibitors, anti-wear, and alkalinity improvers.

It would also be best to prioritize additives with enough zinc and phosphorus elements. Zinc ensures that the engine performs smoothly and more quietly. Conversely, phosphorus minimizes friction, wear, and tear.

MPG Increase

Engine treatments aim to reduce friction, improve engine performance, and reduce wear. These features ensure that the engine performs optimally, increasing fuel efficiency. You’ll rely on them to eliminate moisture in the fuel, deposits, and carbon monoxide emissions. This reduction ensures that the engine stays powerful.

Final Thoughts

Engine additives work best when added to the engine before combustion. Yet, you must choose a high-performance option, as this assures you of value for your money. These additives help improve engine performance and get rid of sludge. With the insights above, it will be much easier to select one that meets your needs best.
