7 Best Additive to Quiet Engine Noise And Noisy Lifters

You may wonder, what’s the best additive to quiet engine noise?

I’ve always enjoyed quiet driving, and nothing drives me nuts like a noisy road trip.

If you’ve dealt with things like road noise and probably fully soundproofed your car, well, a noisy lifter tick can ruin your quiet drives.

Engine noise can be a result of a faulty hydraulic lifter.

You can easily distinguish as it produces a sort of tapping sound. (Original)

Luckily, there are a variety of oil additives that you can use to stop lifter noise and engine knocking.

What Is the Best Oil Additive to Stop Engine Ticking?

For close to three years, Sea Foam SF-16 has been my favorite oil additive to stop engine ticking noise.

This motor treatment is 100% petroleum-based making it perfect for your engine and the environment.

It’s Environmental Protection Agency registered as an environmentally friendly oil additive.

One of Sea Foam’s best features is that it removes contaminants, varnish deposits, and gum from the engine.

This cleanse gives more power to older engines while quieting them down since they do not knock as much.

Some of the areas the SF-16 additive cleans include injectors, passageways, carb jets, and timing chain tensioners.

It also dissolves oil deposits inside the crankcase while lubricating the intake valves, cylinders, and pistons.

A single use of this product will stabilize the diesel and gas fuel for up to two years, making it a worthy investment for your engine.

Best Additive to Quiet Engine Noise Buyer Guide

Additives are worth investment and will keep your engine running efficiently.

However, you must get the right type if you want to get the best out of engine additives.

There are a few factors to consider when shopping for a quiet engine additive. These factors include:

Viscosity

Generally, the thicker the oil additive, the better. However, you also have to consider the engine and the openings inside it.

For an engine with narrow openings, you are better off with a thinner additive that will easily penetrate all surfaces.

Since the additive doesn’t change the thickness of your engine oil, you will realize that your engine works whatever viscosity you choose.

If you aren’t sure if your additive of choice is good for your engine, ask the manufacturer. Your car mechanic may also be resourceful where selecting a good engine additive is concerned.

Composition

Additives come with different ingredients, so you need to check these before making a purchase.

From the ingredients, you easily tell what the additive will do for your engine.

For example, if the additive contains zinc, then you know that it will boost your engine’s performance in addition to keeping it quiet.

An additive with phosphorous works to minimize wear and tear and is ideal if you want to incorporate preventative maintenance into your engine.

Engine Type

Some additives are engine-specific, so you have to check the label when you go shopping. Some additives only work for the gas engine, while others are multipurpose.

If you have a few engines that need additives, go with the multipurpose option.

You may not use a whole container of additives in a small engine, and there is no need to buy two types if you can find one that can work for different engines.

Engine Needs

So, why are you using additives in the first place? Did something happen to trigger this action?

Maybe your lifters are getting too noisy for comfort even with regular oil changes. You may also simply want to protect your engine to ensure that it serves you well.

Whatever your engine needs, you can be sure there is an additive for it.

Whether yours is an old engine that you want to give some life or you are concerned about the rising noise from your engine, you will find an additive to fulfill your problem.

Just explain to the attendant at the shop what your needs are. When shopping online, check the description and see what the additive will do for you.

Do not assume that an additive isn’t good because you do not feel the effect right away.

It will take a few miles for the additive to circulate throughout the engine.
