Before starting, do you think can noisy lifters cause damage? The ticking sound of a lifter is quite normal for the first few seconds when you start the engine. But the continuation of this sound for a long time indicates the red signal of your car.
The jammed or faulty lifter causes the pushrod to bend and fall out of space. This leads to a dead cylinder that might break valves, rocker arms, or even damage the entire engine. Tappit noise indicates the deposition of debris and carbon deposits in the parts due to wearing and tearing.
Will Synthetic Oil Quite Noisy Lifters (Answered)
To improve performance and quiet hydraulic lifter use fully synthetic oil, for example, Castrol Edge High Mileage Full Synthetic Motor Oil is a proven additive that significantly quiet noisy engines.
Synthetics use higher quality base oils and is the top viscosity recommendation by automakers.
Synthetic oil has numerous benefits that never fail to satisfy car owners.
Benefits of synthetic oil
- Better low and high-temperature viscosity performance.
- Resistance to oxidation, thermal breakdown, and oil sludge problems.
- Last longer and offer more engine protection.
- Higher-quality additives that protect, clean and do not degrade as quickly between oil changes.
- Resisting oil breakdown, which makes it last longer.
- Better viscosity index (VI).
- Better chemical and shear stability.
- Decreased evaporative loss.
Note: (Motor oil formulas roughly 20% additives).
Its extraordinary characteristics eject the lifter problems. Despite being a perfect lubricant, the cons of it do not let it reach up to the mark. Yet this oil is considered the best compared to conventional oil.
To remove your confusion, read will synthetic oil quite noisy lifters article to know precisely what synthetic oil does to a noisy lifter.
Car Lifters in Brief
A car’s hydraulic valve lifter is known as the car lifter. It is a small cylinder that has been added to the car’s hydraulic valve with a rocker arm. Generally, the car lifter is situated between the camshaft and the cylinder valves.
There are two types of lifters used in cars – hydraulic and mechanical. Despite being expensive, hydraulic lifters are widely used. Mechanical lifters are cheap and easy to maintain.
A car lifter ensures smooth running and efficient performance of the car engine. A lifter becomes noisy for many reasons. Oil is the most crucial element for a lifter and is responsible enough for any sound in the lifter.
3 Reasons Behind Noisy Lifters
Many reasons make noisy lifters. As this article focuses on engine oil, so let’s know the role of oil behind noisy lifters first.
- The wrong choice of oil creates noise because the oil does not match with the engine then. As a result, friction increases, also noise and leaks. Leaks reduce the chance of adequate lubrication of every part. Consequently, the internal pressure of the engine keeps increasing as well as noise.
- Again, when the parts rub against each other, dirt, debris, sludge form. They get mixed with the oil automatically. Contaminated engine oil causes noise. Also, if the oil level of your car is low, the noise will form then.
- Too old, damaged, or broken lifters are prone to noise problems. The gap between the parts of the lifter causes the formation of noise. A bent or curved rocker arm accelerates the noise also. Moreover, lack of maintenance of the engine plays another essential role behind noisy lifters.
Damage to a Car by Noisy lifters
Suppose your favorite car suddenly is showing some weird behavior. An unfamiliar sound is coming from it. You are thinking of switching to synthetic oil, and you wonder will synthetic oil is quite noisy lifters.
Generally, the dirt and mud formed inside the engine are mainly responsible for noisy lifters.
To remove the noise, you must keep the engine clean and use the best oil.
Noisy lifters significantly affect the performance of the engine. If not taken care of, more problems will come because of noisy lifters. Moreover, noise coming from the engine can be fatal for you too.
Continuous ticking, tapping, or clicking sound will create a distraction. You may not be able to hear a horn coming from a train or other vehicles. The result is an accident for sure.
Easy ways to quiet noisy lifters
To avoid ticking, tapping, or clicking sounds, you must take care of the engine entirely. Change the current oil and switch to a new and suitable one (synthetic oil). Also, use oil additives to keep the engine lifter clean and smooth. Liqui moly hydraulic lifter additives are the best option for this.
For a better experience, use Rislone Engine Treatment Concentrate. It reduces friction and wears and quiets noisy lifters and valves.
Oil Additive-best additive to quiet lifters
I recommend using Liqui Moly 2037 Pro-Line Engine Flush. It’s inexpensive and highly efficient. Easy way to clean and flush the oil systems of gasoline and diesel engines and dislodge any debris or carbon deposits accumulated within the engine.
The Rocker arm or the pushrod of the engine needs to be straight for proper functioning. So change the bent rod soon.
Make sure that there is not an inch left among the valves, camshaft, and pushrod. If necessary, remove the too old parts and place new ones.
Before shifting to new oil, check for leaks. Fix the leaks properly so that oil does not slip out easily. Also, choose a good quality oil that works great in both hot and cold temperatures.
Thicker oil for noisy lifters
Between thicker oil and thinner oil, thicker oil increases the lifter noise more than a thinner oil. The viscosity level of the thinner oil is not satisfactory and does not provide enough lubrication.
On the other hand, thicker oil is dense enough to flow slowly on every part, primarily through the tiniest holes. Thus noises increase non-stop.
When cold, noisy lifters need a fast and spontaneous flow of oil. This is what thicker oil fails to do. When an engine is switched on, parts get hot sooner than the thicker oil.
As thicker oil needs time to get warm, parts suffer from dryness and create a lifter tick sound.
Best oil for noisy lifters
In a word, synthetic oil is perfect for noisy lifters. Its viscosity level is comparatively better than conventional oil. Conventional motor oil is expensive, does not dissolve easily, and evaporates quickly. Also, in freezing and heat, it creates malfunction in the lifters while lubricating them.
To be specific, synthetic blend oil is the best option for the car engine. It contains both plain synthetic oil and conventional oil. Therefore, you will get to experience the pros of both synthetic and conventional oil.

Difference between high mileage oil and synthetic blend oil
The main difference comes from their names. High mileage oil is for cars that have mileage limits over 75,000 miles. High mileage oil is best known for its superb features. It contains some chemicals that work as additives and seal enhancers. Thus, this oil perfectly reduces all internal and external leaks. It is another noise reducer.
On the other hand, synthetic blend oil is best for towing heavy loads. This oil is not generally preferable for high mileage cars, though some say that synthetic blend is suitable for high mileage.
Synthetic blend oil is the best liquid for trucks and SUVs. Where the chemicals of high mileage oil swell the gaskets and seals to prevent leaks, the synthetic blend oil is the opposite. Because of its tiny molecules, it makes its way through the microscopic cracks.
Leaks for switching to synthetic oil
People like synthetic oil most for its naturalness. As being thinner than conventional oil, synthetic oil flows more naturally. This oil is an engine-friendly oil. Conventional or thicker oil does not flow smoothly, instead causes internal and external erosion between parts.
And creates leaks in the engine. Synthetic oil is a thousand times better in this case.
Still, there is a problem with synthetic oil. If there is already a leak because of mismatched oil, synthetic oil can not do anything about it. It smoothly slips out through the leak. As a result, all the parts do not get adequate lubrication, and lifters make noise.
Possibility of synthetic oil reducing the noise of lifters
In most cases, synthetic oil quiets the noise of engine lifters. However, there are thin chances that synthetic oil does not lessen the tick sounds of lifters. If the hydraulic valve lifter of your car is broken, then using synthetic oil is useless. The engine then sounds louder with synthetic oil.
When you start a car, the engine gets hot quickly, but synthetic oil does not. It takes a bit of time for synthetic oil to get hot and reach all the parts of the engine. Until it reaches the parts correctly, noise forms, Delay in changing the oil can make noise in the lifters too.
Sometimes noise caused by synthetic oil leads people to return to conventional oil.
Sludge by synthetic oil
Synthetic oils do not produce sludge instead, and they lessen the formation of sludge. Like normal or conventional oils, synthetic oils do not break and evaporate quickly. Because they have a constant viscosity level.
What oil is the best for noisy lifters?
Synthetic oil, specifically synthetic blend oil is the best for noisy lifters. Conventional oil is the worst choice for car engines. A high mileage car engine requires high-end oil to reduce noise and leaks. Before that, an inspection of the engine is a must. Well-conditioned engine parts with synthetic oil give a heavenly experience.
Does synthetic oil stop lifters?
Not entirely. In few cases, synthetic oil makes the lifter sound louder. Worn-out engine parts and existing leaks are highly responsible for this. If you recently shifted to synthetic oil, and notice no change in noisy lifters, then do not be surprised. Previously used oil in your car engine made the engine unfriendly for synthetic oil to work correctly. Irregular change of impure synthetic oil can cause noise too.
How can I make my lifters quieter?
First, take a proper inspection of the car engine first. After that, stop or reduce everything that causes noise in the lifters. Fix the parts, use the best oil, use suitable additives to clean the sludge, and change the oil regularly. If these sound hard, take your car to an efficient car mechanic.
What causes lifters to knock?
Improper maintenance of the engine primarily causes lifters to knock. Dirty engine oil, the gap between the lifter parts, damaged lifter, and low engine oil level are the main reasons. Additionally, leaks and extreme temperatures create obstacles to the natural flow of oil. Consequently, lifters become noisy.
Can noisy lifters cause damage?
Noisy lifters cause severe damage to the car. If you do not give your attention to the noisy filters in time, erosion, as well as noise, will keep increasing. Gradually they will accelerate the damage inside the engine. Your car will collapse suddenly. Due to noisy lifters, your driving will be disturbing. And you may fail to hear any critical sound.
Ensuring a car’s long life is not so easy. Like humans, machines also need care, better to say special care. A car’s engine is quite complicated to understand exactly where the problem is.
A noisy lifter is not something ignorable, as it has the power to wreak havoc all over the engine. Therefore, you need to be alert when you first hear the tick, tap, or click sound. Consultation with a proficient mechanic will lighten your worries and ensure proper servicing of your car.
