A lifter is a cylindrical part in your engine that works to keep it quiet and running smoothly for longer. These parts apply pressure and open the valves to achieve these goals.

Lubricating the lifter periodically can help it function a lot better. If you are on this page, it means that you are having an issue with your lifters being noisy.

This could be the effect of using the wrong lubricating oil or it is too old. Or sometimes, it could be because of dirt and sludge present in your engine and, in some cases, the lifters are too old. We have found that the easiest solution to fix the noise is to use oil additives.

Oil additives are an addition to the engine oil that augments their functioning. Engine oil works to lubricates the parts of the engine to reduce friction and the oil additive keeps those parts covered smoothened.

Quick Answer: Top Oil Additives for Engines

How to Choose Oil Additives: What to Look for?

Before you buy an oil additive, here are some factors to consider that will help you choose the right one:

There are many kinds of oil additives including oil thinners, oil thickeners, and flushing agents. However, oil additives are the most effective ones to silence noisy lifters.

These products break down the debris inside the engine while preserving the properties of the oil you’re using.


It’s a common myth that the thickest oil additive is the most functional. Sometimes it may well be the opposite as the oil needs to be thin enough to flow through the tubes inside the engine. If you have a narrow engine, a thin fluid will do a better job flowing in them.

Clearing and Preventing Debris

Of course, the primary function of an oil additive, in this case, is clearing the debris and rust from the valve train. These impediments make it hard for the lifter parts to do its job properly.

This is the most common reason for the creaky noises when you are driving. The oil additive should flush away the rust and debris while moving through the passages and keep them lubricated enough to prevent their return.

A good oil additive should be able to adjust to high temperature and optimize performance. If your car blows coughs up thick black smoke from your exhaust, an oil additive may be a good solution. It reduces the engine oil loss that ends up causing thick smoke to blow out of the exhaust pipe.

Improving Engine Performance

While oil additives can reducing the irritating noise from your lifter, some of them can also improve the performance of your engine from within.

As the addition of an oil additive can prevent friction and subsequent heat inside the engine, it can help improve the life of the vehicle. A good branded oil can also act as an oil stabilizer. It can thicken the engine oil which upon regular use, increase your gas mileage.

Chemical Composition

You are definitely not expected to be an engineer but just glancing at the manufacturing label can give you information about what’s in the product.

Most oil additives will contain mineral oil or petroleum distillates but products with Zinc or Phosphorus will boost their performance.

They’ve also been proven to prevent quick wear and tear of your engine components.


Some oil additives have EPA certification which means that it does not contain harmful substances, while also reducing dangerous emissions. If being kinder to the environment is a priority to you, check for the EPA certification on the label before buying


Not all oil additives only work on all kinds of engines, some work only For only synthetic oil engines. Be careful to check the manufacturer’s recommendations before purchasing.

This is important as using the incorrect oil viscosity may affect the engine oil too much. If you’re unsure about any specifications of your car, ask the nearest mechanic to help you out.
