Gear oil additives: rating of the best and driver reviews

Not only the transmission, but also the motor is facilitated in work, if the contents of the tube (9 g) are introduced into the gearbox with a volume of up to 8 liters. The restoring agent, having dissolved in ATP of any type, lays down in an even layer on the rotating auto components, preventing their destruction.

Howling, noise, crunching are the first signs of a transmission malfunction. Then there are leaks, incorrect switching of speeds. But do not rush to the service station: in many cases, additives in gear oil successfully solve the problem. There are heated discussions on the benefits of auto chemical products on driver's forums: and the arguments of opponents are weighty. The topic requires an impartial disassembly.

Why do we need additives in manual transmission

Transmission is a loaded unit in which there is active friction of gears, rolling bearings, shafts, synchronizers. The process is characterized by a large release of heat: without lubrication, the mechanism will not work even for several minutes.

Additives in manual transmission Liquid Moli

When functional factory additives burn out from base oils, drivers revive the transmission fluid (TF) with concentrated additives.

The effect of the use of drugs is as follows:

• A polymer film is formed on the surfaces of the gearbox parts, which facilitates friction.
• Microcracks are filled, the configuration of the gearbox elements is partially restored.
• Dissolves tight carbon compounds from the walls and components of the gearbox.
• The cavities and oil lines of the unit are cleaned. At the same time, metal chips and dirt remain in suspension.
• Improved performance of oil pumps.

Rubber and plastic gaskets do not collapse: on the contrary, auxiliary chemical compositions make the seals soft, the joints of the transmission parts are airtight.

How additives affect

The result of the use of additives is the reduction of extraneous sounds and vibration, the extension of the operational life of the assembly. Owners notice smooth gear shifting, improved dynamics, and lower fuel consumption. However, for a positive result, you need to choose and apply additives correctly.

Rules for the use of additives in gear oils

The additive of preventive action must be added when changing the oil, stirring the liquid directly in the canister.

If the lubricant is already filled into the box, narrow-purpose substances (restoring, antifriction) are introduced in the middle of the interservice period through regular ways: an oil filler neck, an inspection hole or a dipstick. Sealants are used at the first sign of a leak.

At the time of the procedure, the transmission fluid should be warm. After pouring chemical compounds, drive the car in a quiet mode, shifting gears one by one.

The action of drugs affects after 300-500 km. Do not allow an overdose of auto chemicals, as well as an insufficient amount.

The best additives in manual transmission

The Russian market of fuels and lubricants is flooded with thousands of items in this category. To understand the materials and identify a good product, ratings compiled according to the results of tests and tests of the compositions help.

Liqui Moly Gear Protect

A review of the best begins with a German-made drug, which is dominated by molybdenum disulfide, copper and zinc. Particles of soft metals due to the use of the substance of the company "Liqui Mole" as a restorative agent for old units with obvious signs of wear.

Mos Two Ultra

The revitalizant additive is effective in relatively new boxes that have not experienced serious mechanical damage. The material forms a strong protective film on the surfaces of the structural elements of the manual transmission, which facilitates the friction of the parts that are in engagement: input shafts, gears. The universal drug is mixed with all types of TJ. The working life of the box, according to the manufacturer, increases by 5 times.

Nanoprotec MAX

The oxide film formed by auto additives reliably protects transmission elements from early wear.

Additives Nanoprotec for manual transmission

Thanks to Nanoprotec MAX, the gearbox works smoothly, without jerks and kicks when changing from one gear to another. Along the way, as users note in the reviews, the mechanism stops howling and buzzing.

Liqui Moly gear oil additive

Another German product deservedly entered the lists of excellent additives for mechanics. Liqui Moly produces a molybdenum compound for heavy duty boxes and bridges.

The gel-like preparation is packaged in 20 g tubes: one package is enough for 2 liters of fuel.

Revitalizer "Hado"

The products of the Ukrainian-Dutch joint venture Xado are popular in 80 countries around the world. Silicon and ceramics, included in the chemical formula of the gel, partially modify worn parts, renew the base oil, extending the life of the box.

The material reduces the coefficient of friction, which increases the efficiency of the engine. This is noted by the owners of domestic Lada Vesta, Granta, Kalina.

The best additives in automatic transmission

The design features of automatic, variable and robotic gearboxes require ATP and additives with specific properties. Having studied the materials offered to Russian motorists, the experts compiled a list of really effective drugs.

Liquid Moly ATF Additive

For automatic boxes with a standard volume of 8 liters, a bottle (250 ml) of the German LiquiMoly ATF Additive is sufficient. This allows you to give the factory lubricant new qualities. The formula of the complex additive includes cleaning agents that dissolve and eliminate dirt from the cavities of the box.

Additive Liqui Moly for automatic transmission

Among other tasks: protection against scuffing, prevention of foaming of working fluids, automatic transmission noise suppression.

RVS Master Transmission Atr7

Domestic development consists of magnesium silicates, plasma-expanded graphite, amphibole. The listed substances have a beneficial effect on the state of factory lubrication and the overall performance of the unit. The manufacturer claims that the drug compensates for the wear of gear teeth up to 0,5 mm.

Suprotec automatic transmission

The Russian tribotechnical composition is good as a prophylactic, but it also perfectly restores defective elements of classic automata and CVTs.

"Suprotek" reduces annoying box noises up to 10 dB, makes it easier to switch gears, and protects the assembly from overheating.

SMT2 Hi-Gear

The gap in the shortage of high-quality tuning tools in the domestic fuel and lubricants market was filled by the drug of the American brand High Gear. Molybdenum additive to ATF removes excess heat from rubbing components, closes oil seal leaks. The additive, which motorists call "friction winner", is used in combination with synthetic and mineral oils.

Revitalizing XADO EX120

Not only the transmission, but also the motor is facilitated in work, if the contents of the tube (9 g) are introduced into the gearbox with a volume of up to 8 liters.

The restoring agent, having dissolved in ATP of any type, lays down in an even layer on the rotating auto components, preventing their destruction.

The natural wear of parts is reduced, extraneous noises go away. Revitalization (recovery) lasts 50 hours, or 1,5 thousand km on the speedometer. After this time, drivers notice a general improvement in vehicle performance.

What additives can help eliminate sounds in a manual transmission

When studying the labels of autochemicals to be added to the checkpoint, you will not find a narrowly targeted anti-noise additive. The elimination of sounds comes naturally, as a nice option to the wide range of functions of such a drug.

When the transmission, thanks to useful auxiliary substances, works without failures, there is simply nowhere for noise to come from.

What additives should not be used for gearboxes

High-tech concentrated compounds can be of great benefit or, conversely, destroy the transmission and engine.

Do not use engine oil additives in manual transmissions. As well as automatic transmission fluids.

Be interested in the type of base lubricants in the nodes. Do not mix mineral water additive with semi-synthetics.

Manufacturers accompany car chemicals with detailed instructions, where the first item indicates the purpose of the substance.

What motorists say about gear oil additives: reviews

Drivers argue furiously: "to pour or not to pour." Divided into two camps, car owners on thematic forums give reasonable arguments both for additives and against.

But it is difficult to disagree, for example, that depressant compounds (antigels) make a car start better in the cold. However, skepticism about building up worn gear teeth also seems justified.

Independent experts managed to calculate: 77% of car owners are inclined in favor of additives. But auto mechanics warn that chemicals are a temporary measure, especially in the matter of oil leaks from boxes. It is impossible to cure all the "sores" of the transmission with liquids: in case of significant wear and serious breakdowns, contact a car service.
