Best Additive For Lifter Noise

If your engine is making a ticking or knocking noise when you start it up or while driving, it is a sign you may have a jammed hydraulic valve lifter, jammed lifters affect can engine performance and can lead to more serious problems in the long term, so its best to nip the problem in the bud as soon as you can.

Lifters are part of your car’s oil system and ensure the valve train operates without clearance, reducing noise.           

However, if your oil runs low, becomes dirty, or there is a build-up of grime within the lifter. It loses pressure and begins to tick.

The easiest way to remedy this is to use an oil additive, these break down the buildup of gunk and debris in your oil system, which will reduce the noise and help to keep your engine running smoothly. 

Below we have rounded up the best oil additives for lifter noise on the market, so you can make sure your car will be running as efficiently as possible and get rid of that infernal tick-tick-ticking.

Next on our list is the Archoil AR9100 Friction modifier.

Like a slippery cyborg sent through time to reduce the clattering noises coming from under your hood, Archoil AR9100 Friction modifier is a potent, albeit pricy, oil additive which guarantees to reduce noise coming from your lifters.

AR9100 works by coating the interior of your engine, including the gearbox, and hydraulic lifters with a lubricating film, thereby reducing friction in the part, and with it, noise. 

Suitable for all types of diesel and gasoline engines, Archoil can also help to protect the engine during cold starts, increase engine power and response times, and can even extend the time needed between oil changes.

AR9100 combines extreme pressure additives with highly polarized esters which ensure all parts of the engine are lubricated, reducing a buildup in friction, heat, and noise. 

It is worth noting though that you should only use 1.2oz of Archoil for every quart of regular engine oil.

Archoil proves the old adage that a little can go along way, as each 160z container offers numerous benefits to your car, including faster start times, smoother engine performance, increased mileage, and most important of all, all but eliminates lifter noise.

Coming in a clear plastic 12oz bottle which makes it look like it had been produced at a mad scientist’s clifftop retreat on a stormy night, zMax 51-212 is just as much the scientific marvel its easy-pour bottle alludes to.

zMax boosts performance and extends the life of your engine by cleaning and coating its parts with a thin film, as well as reduce carbon buildup inside the engine.

It can also help reduce emissions in both old and new cars and potentially increase an engine’s horsepower.

What’s more, it gets to work right away, after adding zMax to my our oil we noticed an immediate improvement in the amount of sound produced by our vehicles once noisy lifters.

It’s worth noting though that zMax 51-212 engine formula is powerful stuff and should only be added to your gas or diesel engine once every six months or 6,000 miles. Therefore we would recommend adding it during your next oil change just to be on the safe side.  

With speedy results and plenty of additional benefits, using zMax 51-212 engine formula will help you make sure that your engine lives, damn you, lives, for a long time to come, instead of hearing it ticking down to its demise. 


  • Instant improvements to lifter noise
  • Extends engine life
  • Can reduce emissions while increasing horsepower


  • Does not coat parts as well as thicker oils


Trust the Germans to get straight to the point. As its name suggests Liqui Moly Hydraulic lifter additive has been specifically designed to tackle lifter noise. 

It does this by optimizing the performance of hydraulic tappets within your engine lifter by cleaning and lubricating the ducts and holes within the oil circuit. 

As a result not only is the lifter noise reduced but the overall performance of the vehicle is increased as well. 

Liqui Moly can be used in both diesel and gas engines, and with all types of commercial oils and is safe to use on cars with either a catalytic converter or turbocharger as long as they have an engine which uses 1.6 liters or more of engine oil. 

The only downside to Liqui Moly is that although it works very well, and can often eliminate ticking tappets, the results do wear off over time, and it often takes a few miles of driving before you see results.

If you want something to clean your lifters and stop that irritating ticking sound, without any of the boastful claims of some other brands of additives, Liqui Moly 2004 is the additive for you.


  • Specifically formulated to clean and quiet lifters
  • Stops ticking sounds caused by faulty tappets
  • Removes grime from fuel system  


  • Works well but wears off.
  • Requires you to drive a few miles before it kicks in

Best Additive For Lifter Noise Buying Guide

When your engine’s hydraulic lifters become worn, dirty or lack lubrication they begin to tick loudly, this can also be accompanied by a loss in engine power and performance. 

This can lead to a loss in internal pressure and the adjusters which optimise your engine’s performance to not work as effectively. 

Oil additives are a cheap and effective way of improving performance as they are specifically formulated to improve lubrication of an engine's moving parts, improve the viscosity of the oil already in the system and break down harmful gunk and grime within the fuel system.

Finding the best additive for lifter noise

Oil additives are blends of chemicals which are added to regular motor oil to help it circulate through the engine, the additive works by lubricating parts within the fuel system to reduce friction, and as a result wear and tear, and noise. 

They can also be used to improve the efficacy of an engine, increasing fuel efficiency and extending the time needed before your next oil change.

Most also include detergents to reduce to break down the harmful buildup of sludge and dirt within your oil system.

Each oil additive contains different ingredients which are used to improve engine functions in different ways. 

Below is a list of common ingredients and their function so you can be sure to select an oil additive which is suitable for your needs and your engine.

Lubricating Oil Additives (LOAs) and Extreme Pressure Agents.

These are added to reduce the amount of friction between metal components within an engine. The most common LOAs is phosphorus, while boron and molybdenum are also used as alternatives. Though all of these 

materials are very effective it is worth noting that phosphorus can create a build up of 

unwanted carbon in cars with catalytic converters over time, and therefore should be used sparingly.

Meanwhile extreme pressure agents such as potassium-borate and sulphur-phosphorus form a film on the surface of metal parts which is resistant to the high pressure created while an engine is running thus reducing wear and tear. 


This is often combined with phosphorus to  boost an engine's overall performance and efficacy. Like Phosphorus, zinc should be used sparingly as overuse can damage catalytic converters.      


These are added as a means of increasing horsepower and fuel economy. The most common of these is Titanium oxide, which is known to  reduce sound within the engine quickly and also does not cannot damage a catalytic converter like zinc and phosphorus compounds can.
