Will Synthetic Oil Quiet Noisy Lifters? The Truth Revealed

Synthetic oil has been a popular topic of discussion among car enthusiasts and mechanics alike. One of the most common questions asked is whether synthetic oil can quiet noisy lifters. The short answer is yes, synthetic oil can help to quiet noisy lifters, but it depends on the underlying cause of the noise.

Lifters are an essential component of the engine that help regulate the flow of oil and ensure proper lubrication. If lifters are not lubricated correctly, they can produce a ticking noise, which can be quite annoying. While using synthetic oil is not the only solution to the ticking noise of the lifters, it can help the engine in other ways.

Synthetic oil is formulated from lubricants with superior properties than traditional petroleum-based motor oils, such as improved oxidation stability and increased viscosity index levels, which can help ensure better lubrication.

What are Noisy Lifters?

Noisy lifters are a common problem in engines. Lifters are small cylinders that help transfer the motion of the camshaft to the valves. They are crucial components in the engine and if they start to make noise, it could be a sign of a more significant problem.

The lifter noise is usually a ticking sound that is most noticeable when the engine is idling. It can also be heard when accelerating or decelerating. The noise is caused by the lifter not being able to maintain proper contact with the camshaft due to wear or lack of lubrication.

There are two types of lifters: hydraulic and mechanical. Hydraulic lifters are more common in modern engines, and they use oil pressure to maintain contact with the camshaft. Mechanical lifters, on the other hand, are adjusted manually and do not require oil pressure.

Lifter noise can be caused by several factors, including:

  • Lack of lubrication
  • Worn lifters
  • Dirty oil
  • Low oil pressure
  • Incorrect valve adjustment

Ignoring lifter noise can lead to more significant engine problems, such as camshaft wear or damage to the valve train. It is essential to diagnose and fix the problem as soon as possible to avoid costly repairs.

What is Synthetic Oil?

Will Synthetic Oil Quiet Noisy Lifters

Synthetic oil is a type of engine oil that is artificially made using chemical compounds. It is designed to offer better performance and protection to the engine than conventional mineral oil. The synthetic oil molecules are more uniform in size and shape, which makes them more resistant to breakdown and wear.

Synthetic oils are formulated to offer better lubrication and protection to the engine components, especially under extreme conditions such as high temperature and pressure. They also have a higher viscosity index, which means they maintain their thickness and consistency better than conventional oils, even at high temperatures.

Synthetic oils are available in different formulations, including full synthetic, synthetic blend, and high mileage synthetic. Full synthetic oils are made entirely from chemical compounds, while synthetic blends are a mixture of synthetic and conventional oils. High mileage synthetic oils are designed specifically for engines with high mileage and offer added protection to aging engines.

One of the main benefits of synthetic oil is that it lasts longer than conventional oils. It can go up to 10,000 miles or more between oil changes, depending on the driving conditions and the type of synthetic oil used. Synthetic oils also help to reduce engine deposits, which can lead to better fuel efficiency and reduced emissions.

Overall, synthetic oil offers several benefits over conventional oil, including better performance and protection, longer oil life, and improved fuel efficiency. However, it is important to note that not all engines require synthetic oil, and it is essential to check the owner’s manual or consult with a mechanic before switching to synthetic oil.

Can Synthetic Oil Quiet Noisy Lifters?

Synthetic oil

Yes, synthetic oil can help quiet noisy lifters. Synthetic oil has better lubricating properties than conventional oil, which can reduce friction and wear on engine parts. This can help prevent lifters from becoming noisy or ticking. Apart from that, synthetic oil is more resistant to breaking down under high temperatures, which can also help prevent lifter noise. However, it’s best to keep in mind that, noisy lifters can also be caused by other issues, such as low oil pressure or worn lifters, so it’s always best to have a professional mechanic diagnose and repair the issue.

How Does Synthetic Oil Work?

Synthetic oil is made up of a combination of chemically engineered compounds and additives. These compounds are designed to provide superior lubrication and protection for your engine compared to conventional oils. Synthetic oil has a more consistent molecular structure, which allows it to flow more freely through your engine and reach areas that conventional oil cannot. This improved flow and lubrication can help reduce engine noise, including noisy lifters.

Benefits of Synthetic Oil for Noisy Lifters

One of the main benefits of synthetic oil for noisy lifters is its improved lubrication. If the lifter noise is due to a lack of lubrication, synthetic oil can help reduce the noise by providing better lubrication to the engine. Additionally, synthetic oil can help reduce engine wear, which can also contribute to engine noise over time.

Another benefit of synthetic oil is its ability to resist breaking down under high temperatures and pressure. This means that synthetic oil can maintain its viscosity and lubrication properties for longer periods, even under extreme conditions. This can help reduce engine noise and prevent damage to the engine.

Limitations of Synthetic Oil for Noisy Lifters

While synthetic oil can be beneficial for noisy lifters, it is not always the solution. If the lifter noise is due to a mechanical issue, such as a worn lifter or camshaft, synthetic oil may not be able to reduce the noise. Additionally, some engines may not be compatible with synthetic oil, so it is important to check your owner’s manual before switching to synthetic oil.

As you can see, synthetic oil can be beneficial for reducing noisy lifters in some cases. However, it is not a guaranteed solution, and there may be other factors contributing to the noise. It is important to consult with a mechanic to diagnose the cause of the noise before switching to synthetic oil.

How to Use Synthetic Oil for Noisy Lifters?

If you are experiencing noisy lifters in your car, using synthetic oil can be an effective solution. Here are some tips on how to use synthetic oil for noisy lifters.

Choosing the Right Synthetic Oil

When choosing a synthetic oil, it is important to consider the viscosity and quality. A high-quality synthetic oil with a viscosity that matches your car’s manufacturer recommendations will provide the best results. Look for synthetic oils that meet the American Petroleum Institute (API) standards and have the “starburst” symbol on the label.

Changing the Oil and Filter

To use synthetic oil for noisy lifters, it is important to change the oil and filter. Start by draining the old oil and removing the old filter. Replace the filter with a new one and add the recommended amount of synthetic oil. Be sure to check the oil level and add more if necessary.

Other Maintenance Tips

In addition to using synthetic oil, there are other maintenance tips that can help quiet noisy lifters. Regular oil changes, using high-quality fuel, and avoiding harsh driving conditions can all help prevent lifter noise. It is also important to keep up with regular maintenance tasks, such as changing air filters and spark plugs.

By following these tips, you can effectively use synthetic oil to quiet noisy lifters in your car. However, if the noise persists, it may be a sign of a more serious issue and should be inspected by a professional mechanic.


Synthetic oil is a great option to consider if you have noisy lifters. Its superior lubricating properties and resistance to breaking down under high temperatures can help reduce friction and wear on engine parts, which can ultimately lead to quieter lifters.

However, it’s important to remember that noisy lifters can have various causes, and synthetic oil may not be the solution to every case. Consulting with a professional mechanic is always recommended to properly diagnose and address the issue.
