Rating of the best additives for manual transmission for 2022

Over time and the operation of the car, the gearbox begins to make extraneous noise, rattle, and so on. This occurs due to increased clearances between parts or bearing play. An additive will help improve the condition and maintain the performance of the car in this situation.

What is an additive

An additive is an automotive chemical that is added to fuel in a small amount to restore the performance of car parts.

The popularity of this autochemistry is due to the fact that with its help you can get rid of most of the problems without resorting to physical disassembly of the vehicle.

• Liqui-Moly is a German company that produces a large number of auto chemicals. Often new methods and advanced technologies are used in the manufacture, this explains the high price in the market.
• XADO is a Ukrainian brand selling oils and lubricants. It has one of the largest selections of additives for manual transmission and engine.
• Fenom - produces cleaners, aerosols, anti-gels, etc. It has the best value for money.
• Suprotec is another German company that has firmly established itself with users due to its quality, wide range of products and price.
• VMPAUTO - a company from Russia produces restoring and lubricating additives for manual transmissions. Wide selection and reasonable price.

How to choose an additive for manual transmission

In order to determine which additive is needed in your case, it should be borne in mind that they are divided into a large number of types for their intended purpose:

• Anti-corrosion - from the name it becomes clear that they slow down the oxidative processes of the metal and protect gearbox parts from rust;
• Sealants - stop the flow of oil from the box by restoring the elasticity of the seals;
• Revitalizants - fill empty spaces in parts and remove excessive noise, reduce backlash in parts;
• Anti-seize - protect moving parts from wear and create a protective film on their coating;
• Antifriction agents - protect the oil from freezing in the cold season;
• Cleaning agents - destroy various dirt and plaque on the metal. Usually used a couple of days before changing the transmission.

Rules for the use of additives

For the greatest effectiveness, additives should be added to the oil when it is still in the canister. If the oil has already been changed, then you can pour the additive directly into the mechanism through the filling hole. Pouring an additive into old oil has the risk of not only not improving transmission performance, but, on the contrary, worsening it. Since the old oil loses its absorbency and cannot dissolve the additive components. If the oil has already been changed, then you can pour the additive directly into the mechanism through the filling hole. Important! The oil must be well warmed up.

Also, before buying an additive, always read for what purposes this composition is used, with which oil it is compatible and other characteristics. In rare cases, the additive can turn the oil into a jelly-like mass.

Where could I buy

If you have a desire to buy additives, then this can be done in specialized stores.The advantage of this method is that you can consult with the seller and determine as correctly as possible which additive you need. There is also an option to order an additive in the online store. Also quite a good way with its pluses. For example, you do not need to go anywhere, and prices on the Internet are often less than in stores. You can also order a parcel by courier and it will be brought to your door.
