Selecting factors to choose best additive to quiet engine noise

Before buying an oil additive, certain factors need to be considered. These factors taken into consideration gives the best oil additive that meets the requirements of your car engine perfectly.

• Viscosity – Depending on the size of the openings of the tubes in your car, the choice between the thick and the thin oil varies. While the thickest oil additive is considered the best it all boils down to the openings inside the car engine.
  If you see that your car engine has narrow openings or tubes, a slightly thinner additive will be perfect. For an engine with wider openings, a thicker oil additive will be the best.

However, the viscosity of the additive doesn’t have any effect on the thickness of the engine oil that you are using.

• Additive composition – Before purchasing any type of oil additive it is very important to check the ingredients. It will help you narrow down precisely what you need for your car.

Different ingredients in these additives serve different purposes and also affect the engine differently.
For example, zinc is an ingredient present in additives that boosts engine performance and when an additive with this ingredient is added, it will not only keep the engine quiet but also will improve the performance.

• Mile per gallon increase- A good oil additive should lubricate the engine, reduce friction, prevent wear and tear and also make the car run smoothly. These factors may seem enough but it doesn’t hurt to invest in an additive that would also boost the performance of your engine.

There are many companies that advertise their products as EPA approved or endorsed. Keep in mind that these are most likely to be scams as EPA does not endorse or approve or even certify additives.
