Transmission oil zic 75w90 synthetic reviews from car enthusiasts

Manual transmissions have always been distinguished by their durability and unpretentiousness in terms of the choice of lubricant. However, even a structurally strong manual transmission, drive axle or transfer case can quickly be brought to its limit if the oil is incorrectly selected.

The article will discuss synthetic gear oil ZIC 75W-90 and reviews about it. We will also briefly examine the characteristics of this lubricant, its objective advantages and disadvantages, as well as its main performance characteristics.

What explains the need to use gear oils?

Transmission mechanisms are constantly in operation and experience loads and strong friction. To reduce wear, you need to reliably protect all elements. To do this, a lubricant is poured into the gearbox, which performs several functions at once:

Protects the transmission from wear, increasing service life and reducing the risk of breakdowns;
Maintains the required level of pressure in the system, without which the operation of the transmission is impossible. If it falls, then problems appear in the operation of the gearbox;
It cools the torque converter, the circuit of which runs throughout the entire unit and releases a lot of thermal energy. Transmission oil removes excess heat and transfers it to the environment through the radiator;
Protects parts from friction and scuffing. The gears are in constant contact with each other, and the oil helps prevent their wear and jamming.

To prevent gearbox breakdowns, you need not only to fill this unit with high-quality lubricant, but also to promptly replace the fluid. Transmission oil should be changed, on average, every 50-60 thousand kilometers; if the car is operated in extreme conditions, then every 30-40 thousand. This depends on the type of gearbox and the quality of the oil. It turns out that by immediately choosing high-quality products, you not only reliably protect your equipment, but also save money.

A little about the ZIC brand

This trademark belongs to the manufacturing company SK Lubricants. The corporation is located in South Korea; it was founded in 1962 for oil production and refining, and the production of lubricants began in the 90s of the last century. It was then that the company developed a high-quality synthetic base for its oils, which is still considered one of the best in the world. The Yubase base is the main component of all lubricants, including ZIK gear oils. It is supplemented with various additives that improve the characteristics of liquids.

Now the company has one of the largest production facilities with an excellent raw material base, offering mineral, semi-synthetic and synthetic oils for engines, transmissions, as well as various industrial lubricants for special equipment and industrial equipment. The ZIC product range is really wide.

It should also be noted that all ZIK oils are tested at testing sites and in laboratory tests, which provides a certain guarantee from the manufacturer. At the same time, transmission fluids have a fairly average price, so they are available to a wide range of consumers. You can buy ZIK gear oil in almost any auto supply store. You can choose the right lubricant for almost any car.

Secondary, but no less important parameters

Let's consider some other important points regarding the ZIK 75W-90 gear oil.

Package. The ZIK 75W-90 transmission is supplied in 1 and 4 liter containers. According to reviews from car owners, these are optimal volumes. A 4-liter canister is almost always enough to replace in any manual transmission. And there is still a little left in case of topping up. And it’s convenient to buy liter cans separately for refilling or refueling small-sized transmission units (drive axles, transfer cases, etc.).
Price. Perhaps the most interesting parameter. For synthetics, ZIK 75W-90 is relatively inexpensive, even for domestic oils. And if we compare it with foreign analogues, then the oil in question has practically no competitors in this price category. There are also semi-synthetic options in the ZIK gear oil line, which are even cheaper.
Presence of counterfeits on the market. Initially, it may seem that this oil should not have counterfeits, since counterfeit manufacturers usually look only at expensive, well-promoted brands. However, the growing turnover of motor and transmission oils attracts the opportunity to make money through large quantities. And inexpensive lubricants usually receive less attention in terms of identifying counterfeits than well-known brands.

ZIC transmission oils for gearboxes of domestic and foreign cars are increasingly used today in the Russian Federation. Low cost combined with impressive characteristics have made this brand one of the most popular on the Russian market.

Features of ZIC gear oils

Since the company has excellent capabilities for synthesizing base oils from natural gas and oil, the entire liquid production stage is carefully controlled at each stage. This allows us to guarantee consistently high quality products. In addition to the base, the company's specialists with many years of experience develop various additives that improve the characteristics of transmission oils. They allow:

Ensure consistency of viscosity indicators over a wide range of temperatures and loads. That is, the oil will create a durable film on all transmission parts that will not collapse when overheated;
Increase the flash parameter value and lower the temperature threshold. This makes it possible to use ZIK gear oil even in cold regions and at low temperatures.

It should be noted that all produced lubricants have approvals and certificates, which allows their use in different types of equipment.

Types and description of oils

Within the viscosity range under consideration, the company produces two types of lubricant:

ZIC GFF. It is based on semi-synthetic polyalphaolefins (PAO) and Yubase's own base.
ZIC GFT. Fully synthetic lubricant, but has the same base and category.

Both options under consideration are suitable only for manual transmissions. Lubricants protect the internal parts of the gearbox and drive axles, which significantly extends the service life of the transmission. This gear oil maintains its viscosity and positive characteristics at both low and high temperatures.

Specifications

For the GFF and GFT variations they are as follows:

SAE class – 75W-85;
density in grams per cm3 at 15 degrees – 0.85/86;
kinematic viscosity at 40 degrees (in mm2/s) – 61.7/55.8;
at 100 degrees Celsius – 11.8/11.5;
viscosity index – 191/206;
flares: 234/226 Celsius;
loses fluidity - -45/-50 degrees;
acid value – 0.93/4.37 mg KOH/g;
corrosive effect on copper at 100 degrees Celsius – 1-a;
Brookfield viscosity at -40°C, MPa*s – 74753/27884.

To check the figures stated by the manufacturer, you can conduct a test in the cold or when heated. Drivers themselves note the high frost resistance of the lubricant. They note that compared to factory filling, ZIK shows better results in cold weather.

You can see how the oil behaves at -35°C in the video from the author of Romakh 040:

Specification and approvals

Extended drain interval oils GFT and GFF are approved by Hyundai and KIA, and are also suitable for modern foreign cars and comply with the API category - GL-4.

Advantages and disadvantages

The peculiarity of ZIK oils is deep catalytic hydrocracking, which underlies the creation of the lubricant. This technology allows the manufacturer to create a product that differs from “classical” synthetics in a number of advantages.

The positive qualities of the product include:

a complex of additional additives that improve the properties of the fill;
performance at critical temperatures;
possibility of “cold” start;
protection of transmission parts, extension of their service life;
low rate of sediment formation;
operation of parts without vibrations and noise or their elimination;
minimal level of impact on seal materials.

The new technology for manufacturing ZIK oils also has negative sides. Compared to pure polyalphaolefin lubricants, hybrids with Yubase's own base have poorer thermal-oxidative stability.

Based on comments and reviews from drivers using ZIK products, other negative aspects include the fact that the product:

does not fully correspond to the declared characteristics;
does not eliminate existing errors in the operation of the gearbox;
not cheap;
no different from other analogues;
not suitable for very harsh winters;
too thick.

What ZIC gear oils does the manufacturer offer?

Firstly, liquids are intended for any equipment:

For cars, minibuses;
For small equipment;
For freight and commercial vehicles;
For special equipment.

Secondly, you can choose oil for any type of transmission:

For manual transmission;
For automatic transmission.

Most often, ZIK gear oil is purchased for cars with gears.

Thirdly, lubricants are designed for use in various climatic conditions:

Viscosity grade 75W 85 and 75W 90 – can be used at temperatures from -40 to +35 degrees Celsius;
Viscosity grade 80W 90 – suitable for use in the range from -26° to +35°C.

Fourthly, ZIC transmission oils have approvals for different cars, in particular, they are used for the first factory fill in the gearboxes of Hyundai and Kia cars. These fluids are suitable for lubricating parts made of steel and cast iron alloys; they are not recommended for use in mechanisms made of non-ferrous metals.

Analogs

Oils from different manufacturers, created in accordance with the requirements of a specific world standard, have the same basic characteristics. They are analogues of each other.

For example, for GFT the manufacturer itself offers an analogue of GF TOP, and stores offer GM Manual TRANSMISSION OIL produced by GENERAL MOTORS. On forums, drivers also share their positive experience of replacing Zikov grease with GS OIL HD 75W85 API GL4.

You can replace ZIC products with lubricants from popular companies Shell, BR and Mobil. The main analogues are shown in the table.

ZIC	Shell	Castrol	G-Box	Mobile	BR	Liqui Moly
ZIK GF 75W-85	Getriebeoel EP 75W-90	TAF-XS 75W-90	SAE 75W-90, GL-4	MOBILTRANS MBT 75W-90	Energear SGX SAE 75W 90	EP 80W90

Advantages of ZIC gear oils

Liquids are resistant to harsh operating conditions, maintain stable quality and viscosity level;
Characterized by high extreme pressure properties;
Protect transmission parts from corrosion;
They reduce the coefficient of friction in the mechanism, eliminate vibrations when changing gears, and make this process smooth even at low temperatures;
Oil improves sound insulation, making every car trip more comfortable;
The oil has antioxidant properties;
The composition and its components are not aggressive towards polymer seals;
Oils are characterized by high heat resistance;
The low ash content of the composition ensures the absence of deposits on transmission parts, which extends the service life of the fluid and increases the replacement interval.

Oil exhibits all these properties only if it has not yet exhausted its service life. You also need to take into account that specially selected additives provoke a chemical reaction when adding oils from another manufacturer. Therefore, when switching to the use of ZIC oil or, conversely, from it, it is necessary to thoroughly flush the gear shift system.

Advantages and disadvantages

ZIC 75-85 has a number of advantages noted by consumers:

provides reliable protection of metal surfaces and the entire mechanism as a whole from premature wear;
during operation does not change its viscosity properties under sudden changes in ambient temperature;
over a long period of use does not form dirt and deposits in the system, as well as on parts;
minimizes the coefficient of friction in rotating units;
increases the useful power of the manual transmission;
during operation does not destroy sealing material, as well as parts made of non-ferrous metals.

There were no significant deficiencies noted from consumers.

ZIK range of transmission lubricants

The line of gearbox oil includes approximately one and a half dozen items. We will consider the most popular products, which, judging by consumer reviews, deserve the highest quality rating.

ZIC GEAR GF TOP 75W85 AND 75W-90. This synthetic-based oil is used for manual transmissions and main axles. The fluid reduces the coefficient of friction between transmission segments and increases the service life of the mechanism.
ZIC GEAR GF 75W85. This is a semi-synthetic gear oil, which is classified as a premium class. The composition of the lubricant has been improved by adding unique components. This oil is recommended for use in front-wheel drive vehicles operated under moderate loads.
ZIC GEAR EP 80W-90. Product with increased anti-friction characteristics. Made from a mixture of synthetics and a mineral base, therefore it is a semi-synthetic product. This is a good option for cars and trucks, commercial and passenger vehicles.
ZIC G-5 80W-90. Suitable for rare types of transmission mechanisms: hyperboloid, bevel, spiral gears. This oil is particularly resistant to wear and wear and performs well under extreme loads. Forms a durable thin layer of protective film on the surface of metal parts, ensuring the mechanisms are resistant to corrosion.
ZIC GEAR G-5 85W140. Designed for different types of transmissions. A special complex of additives provides increased wear resistance and extends the service life of the gearbox. Suitable for personal and commercial cars and trucks.

Next comes the ZIC ATF series oils. This marking means that the fluids are intended for automatic transmissions. Such transmissions are now the most common, which is why these products are in consistently high demand.

ZIC ATF III. The oil is created for automatic transmissions using a special formula. The additive package added to the composition is versatile. ZIC ATF significantly reduces the noise level during transmission operation and energy loss during engine operation, which increases the efficiency of the gearbox.
ZIC SK ATF SP3. Synthetic gear oil for automatic gearboxes. It has improved viscosity and lubricating properties. The characteristics of the oil reduce noise and vibration, so gear shifting becomes easier and smoother. This not only makes the trip more comfortable, but also extends the life of the unit. ZIC SP3 protects the transmission from premature wear and rust. This product is used for factory refilling of KIA and Hyundai cars.
ZIC SK ATF SP-IV. Represents the latest and most modern generation of transmission oils and is suitable for 6-speed automatic transmissions. Greatly improves the operating capabilities of the equipment.
ZIC ATF MULTI. Suitable for both manual and automatic transmissions. Meets all requirements and international standards of automakers. Shows good lubrication of parts, anti-friction and anti-corrosion properties. Slows down the aging and wear processes of the gear shift system. Along with ZIC SP3, it increases the efficiency of the transmission and increases its service life.

WHY DID YOU CHECK?

And here is what it all started for. We officially declare: the oils are very different and clearly not from the same barrel. The difference in results for individual parameters is not by percentages, but by several times! And the effect does not always correspond to the price. The leader was immediately revealed - the ester Motul Gear 300 has the best performance in terms of welding load, scuffing index, and critical load. The wear is a little worse, but here it’s generally interesting: none of the tested oils met the GOST requirements for the TM-5 group. Why is that? Perhaps this is a consequence of a decrease in the content of sulfur and phosphorus in modern products, which previously determined high anti-wear properties. But the result obtained cannot be considered negative either: we choose oil for manual transmissions of the GL-4 group, where anti-wear indicators are not standardized at all by GOST.

And here is another nuance that was worth working for. It turned out that anti-wear and extreme pressure properties change in antiphase! At the level of intuition this is understandable. The basic principle of wear protection is to place something soft and sliding between the parts. To increase scuff resistance, the opposite is required. Therefore, an effective additive package must provide some compromise between two mutually exclusive factors.

What do consumers say?

Most of the reviews about ZIK transmission products are positive. Consumers most often note the following benefits of this oil:

After a scheduled replacement, the least amount of steel shavings is found in the used fluid, which means that the oil meets all the declared characteristics.
Provides a decent level of protection of parts under extreme operating conditions of the gearbox, allowing to extend the service life of the transmission.
Extends oil change intervals. Thanks to the thermal-oxidation resistance, the car can travel an additional several thousand without changing the transmission fluid without harming its parts.
Acceptable and even below average price. Especially in comparison with analogues.

Among the negativity that sounds in reviews, it is most often associated with the purchase of a fake. Unfortunately, the ZIC trademark is often used by scammers to produce counterfeit products. Next, we will tell you how to purchase original gear oil.

Specifications

Synthetic fluid meets the following standards:

General Motors Dexron 3;
Ford Mercon;
Allison C – 4.

If you are familiar with the first specifications, then you may not have heard of the latter. Allison C-4 is a standard that defines the requirements for transmission fluids in vehicles such as SUVs and trucks. Oil that meets this standard can be poured into automatic transmissions that are operated in severe and extremely severe conditions.

In addition to transmission fluids, motor lubricants are also produced according to this standard.

Write in the comments if you are familiar with the above standards or are you hearing about them for the first time?

How to distinguish fake oil

The main principle is to buy products from dealers with a well-deserved reputation and in trusted retail outlets. There are several elements of protection against counterfeiting: a holographic logo on the label, covering the bottle cap with additional film with printed company symbols, different plastic texture in different parts of the canister (you can feel it by touch).

A fake will have the following characteristic features:

When you press your finger on the handle of a bottle or canister, the plastic bends easily;
The neck of the container is not finished with polyethylene with a logo in an updated design;
The text on the label, located on the back of the package, feels smooth to the touch. On the original bottle it will be felt under your fingers;
The date on the bottom of the canister is poorly punched and is almost unreadable;
There is no hologram on the vertical stripe on the sticker located on the front side of the package.

The manufacturer guarantees that the use of original ZIC gear oil will extend the life of the gearbox in your car, improve the performance characteristics of the mechanism and reliably protect it. To do this, avoid fakes and pay attention to details when purchasing.

Every motorist knows why an engine needs motor oil. But why transmission fluid is needed - not everyone can answer this question. Many car owners believe that gearbox oil is filled for the entire period of its operation. By and large, they are right - in many service books for cars this is exactly what is written.

However, manufacturers did not take into account the operating conditions on Russian roads, under which the transmission fluid needs to be changed every 50–60 thousand kilometers. In addition, fresh oil must be poured into the manual transmission after repair.

Basic properties and functions of gear oil

A manual transmission (MT) requires lubrication just like the engine. Only transmission lubricant ZIC G FF SAE 75W85 works somewhat differently, and its operating conditions differ from those for motors. The structure of the oil remains similar to motor oil - there is a semi-synthetic base and a package of additives that improve its quality characteristics. The base is obtained by using proprietary technology of deep catalytic hydrocracking - VHVI (Very High Viscosity Index), which is displayed on cans of oil. Translation means “very high viscosity index.” What does this mean?

QUESTION ANSWER

Are these types of oils suitable for automatic transmissions?

No good. Special fluids with different properties have been created for automatic transmissions

Here it is very important to follow the recommendations of the manufacturer, because ATF fluid ensures the operation of the torque converter, which requires strictly specified viscosity-temperature characteristics. And for manual transmissions these requirements are much more relaxed.

What is the difference between GL-4 and GL-5 oils? Or, in our opinion, TM-4 from TM-5?

According to GOST 17479.2–85, the purpose of TM-4 group oils is cylindrical, spiral-bevel and hypoid gears operating at contact stresses up to 3000 MPa and oil temperature in the volume up to 150 °C. And the recipients of TM-5 oils are hypoid gears operating with shock loads at contact stresses above 3000 MPa and bulk oil temperatures up to 150 °C. Hence the differences in the required protective properties discussed in the article. Therefore, in particular, switching from GL-4 to GL-5 and back is unacceptable: these are different oils with different properties.

Changing the oil in automatic transmission skoda octavia a5

Will using a more viscous oil reduce transmission noise?

Yes, it will reduce it if the noise is caused by increased gaps in the box components. But within reasonable limits, of course. With a high degree of wear, even the most viscous oil will not help.

Should I chase synthetics? Or is the situation the same as with motor oil?

Synthetics are more stable and therefore guarantee a longer service life. In addition, it has a higher viscosity index, so the low-temperature properties of such oils are better. So there is a certain analogy with motor oils.

Why are there such large numbers in the SAE designations if the weather outside is the same as for the engine?

The numbers indicate the average viscosity range for the oil grade in Saybolt Second Universal Unit (SSU). For transmissions they are taken directly, for motors they are divided in half.

How to change the oil composition in a manual transmission

If a car has traveled 50 or 60 thousand kilometers on one manual transmission lubricant, it’s time to change it. For any manual transmission, the viscosity ZIC 75W85 of any of both brands is quite suitable. ZIK with this SAE indicator is quite suitable for all climatic zones of the Russian Federation, since it has excellent low-temperature fluidity.

As a rule, manual transmissions do not have dipsticks for checking the lubricant level. You can check visually - the level should be at the lower edge of the filler neck. The volume of the required oil composition is indicated in the service book, since it differs for different gearboxes.

Since ZIC 75W85 GL-4 is available in canisters with volumes of 4 l and 1 l, choosing the right volume will not be difficult. To perform the replacement yourself you will need:

new transmission fluid of the required volume;
rags and metal brush;
a set of tools (wrenches or sockets);
a syringe with a hose for pouring lubricant, or a funnel with a hose;
container for draining spent fluid.

The transmission warms up, for this it is enough to drive 10–15 km.
The car is installed above the inspection hole or driven onto an overpass.
The oil filler plug is unscrewed.
The drain plug is released at the bottom, a container is placed under it, and the plug is unscrewed. You need to do this carefully - do not drop it and get burned, the lubricant is hot.
After the liquid has stopped flowing, the drain plug is cleaned and screwed back in. If it has a sealing washer, before replacing it you need to purchase a new one and install it in place of the old one.
Using a syringe or funnel with a hose, lubricant is poured into the oil filler neck to its lower edge. It is advisable to also place a container under it, because lubricant may leak from the neck. Once this happens, the level is enough. The filler plug is screwed into place.

That's all. Now you can safely drive for several more years, enjoying smooth gear shifting.

The transmission is one of the most important components that ensure the normal operation of the car. This mechanism requires timely maintenance. The choice of lubricant must be approached as responsibly as possible. The duration of operation of the gearbox, as well as other components and mechanisms, depends on the quality of the selected substance.

ZIC 75W90 gear oil is in great demand today. Reviews of the presented product will help you draw a conclusion about its quality. The presented product has existed on the market of special products for cars for a long time. What ZIC lubricant is will be discussed further.

Transmission oil (synthetic) ZIC 75W90 (characteristics, reviews, photos are presented below) belongs to the category of new generation high-tech products. It is produced by the South Korean manufacturer SK Corporation. This brand is known as one of the major suppliers of lubricants for Asian mechanical engineering enterprises.

Almost all cars that come off assembly lines in China, Japan, and Vietnam are provided with oils produced by SK Corporation. When producing its compounds, the South Korean company takes into account the highest requirements of modern mechanical engineering. Thanks to this, its lubricant compositions fully comply with the technological and environmental requirements of the world community.

The products of the presented brand are in demand in our country. This is due to the reasonable cost and high quality of the compositions. The presented products reliably protect mechanisms and components from premature wear.

Product Description

ZIK 75W90 is a special lubricant made from synthetic raw materials and is considered completely synthetic. Designed for refueling in Hyundai and Kia. The composition contains substances such as polyalphaolefins, which are obtained during the processing of natural gas. Yubase oil is used as a base; it is produced at the ZIC enterprise and has a high degree of purification, which distinguishes it from its analogues. The base has a long service life and can withstand high loads at elevated temperatures.

ZIC 75W90 contains a complex of enhanced additives made by LUBRIZOL. The quality of the corporation's products has no competition at the moment. In GFT brand gear oil, the manufacturer focuses on increasing the service life of the product. Additives can also reliably protect metal components and parts from premature wear and rust. During operation, they do not form contaminants on the lubrication system. Ignition and complete crystallization occur when temperatures reach 212°C and -47.5°C.

general characteristics

Transmission oil ZIC 75W90 (synthetic), the characteristics of which will be presented below, has a number of features. This product is manufactured using the latest scientific developments. Thanks to its special formula, the lubricant significantly improves the performance of gearboxes.

The presented product is intended for manual transmissions. It is also used for bridges of trucks and passenger cars. Gear oil in this category is suitable for construction equipment.

Property Basis

Using a high-quality base, ZIC 75W90 gear oil is produced. Semi-synthetics and synthetics today are the most popular substances from which consumables for gearboxes are produced. Synthetic lubricants are the most popular. They are made on the basis of special, high-quality oil. It is created using Yubase technology.

The oil base also includes PAO components and balanced additives. Synthetic oils promote rapid distribution of the product within the system. They envelop all the details with a thin layer. This allows the moving elements to slide well.

Semi-synthetic products contain mineral oils. Such compositions are suitable for medium-load conditions. Such substances are replaced earlier than synthetic oils. But their cost will be slightly lower. A synthetic product for manual transmissions made in South Korea provides reliable transmission protection even under high, constant loads.

Description

ZIC G-FF 75w-85 is a fully synthetic oil for manual transmissions, which is designed for transmissions that require the use of GL-4 class motor oils.
Transmission fluid is a specific product developed specifically for manual gearboxes of Hyundai and Kia cars. ZIC GFF 75w85 contains polyalphaolefins, a synthetic Yubase base and an additive package from LUBRIZOL. Understanding the composition, it should be noted that polyalphaolefins are products of natural gas processing that serve as the basis for the production of PAO-synthetic oils.

LUBRIZOL is the world's largest manufacturer of petrochemical additives. The quality of this company's products today has no competition. ZIC 75w85 GFF focuses on anti-wear additives, including corrosion inhibitors. Such additives allow us to reliably protect transmission parts from destruction and premature wear. Timely replacement of low-quality gear oil with ZIC G-FF (if the vehicle manufacturer’s requirements for the lubricant for the gearbox and the technical characteristics of the ZIC oil for the gearbox coincide) can extend the factory life of a manual gearbox.

Yubase is a hydrocracked base oil, which is a proprietary development of ZIC engineers. Its main difference from other hydrocracking bases is the degree of purification and performance characteristics of the product. Oils created on the basis of this base are comparable in their properties to synthetic products and are able to withstand heavy loads, including operation at extended drain intervals. The use of a high-tech base made it possible to create Zik G-FF 75w-85 oil, which has an affordable price and high performance.

An important feature of ZIC G-FF 75w85 is its careful interaction with synchronizers made of non-ferrous metals. In addition to the fact that ZIC gearbox oil is not aggressive to this part, it additionally protects each transmission unit from corrosion and premature wear.

Specifications

Considering reviews of gear oil ZIC 75W90 (semi-synthetic, synthetic), it should be noted the high popularity of the GFT series product. Its technical characteristics indicate the high reliability of the product.

The density of the composition at 15ºС is 0.86 g/cm³. In this case, the kinematic viscosity at 100ºС is 14.1 mm²/s. The quality of the product is confirmed by the high flash point. The oil ignites when it reaches 212ºС. When a car transmission is operating, such temperatures are practically unattainable.

The oil begins to lose its fluidity at a temperature of -47.5ºС. This is a very good indicator. The transmission will work reliably even in severe frost. The acid number meets the requirements of the standards. It is 1.48 mg KOH/g. Experts claim that the data presented by the manufacturer is completely true.

Types and description of oils

Within the viscosity range under consideration, the company produces two types of lubricant:

ZIC GFF. It is based on semi-synthetic polyalphaolefins (PAO) and Yubase's own base.
ZIC GFT. Fully synthetic lubricant, but has the same base and category.

Lubricity

Considering the characteristics and reviews of gear oil ZIC 75W90 (synthetic), which are left by experts in the field of lubricants, it is necessary to note the exact compliance with the standards of the product presented.

The South Korean manufacturer's oil for manual transmissions is manufactured in accordance with GL-4, GL-5 standards. These standards apply to the production of all transmission fluids.

Compliance with the presented compositions indicates the possibility of using the oil in medium and highly loaded systems. The composition includes a sufficient number of additives that can reliably protect the mechanism from adverse effects. Even with an increase in temperature and rotation speeds of mechanisms, the oil will ensure good sliding of the rubbing metal parts.

Additives

Reviews of ZIC 75W90 gear oil indicate the high reliability of the product presented. The manufacturer adds a balanced package of additives to the base base. If a different oil was previously used in the transmission, the system will need to be thoroughly flushed. Additives, entering into a chemical reaction with other components of the old substance, may lose their protective properties.

The South Korean brand oils contain only new, high-quality components. They have several effects on the system. Anti-seize ingredients ensure good sliding of mechanism elements. The oil film does not break and dry surfaces do not appear.

Also contains antioxidant additives. They prevent the development of corrosion and oxidation. The oil can be used for a long time. Its additional filling or complete replacement may be required much less frequently.

Advantages and disadvantages

ZIC GF TOP 75W85 (old name) has the following advantages that distinguish the product from analogues:

as a result of adding a reinforced package of high-quality additives to the composition during oil production, an increase in the service life of the fluid is achieved;
during operation it is not subject to oxidation, does not form soot and oxidation on the surface of parts;
significantly reduces the coefficient of friction in a manual transmission, while increasing the useful power of the mechanism;
over a wide range of operating temperatures does not destroy sealing material, as well as parts made of non-ferrous metals.

No negative properties were noted.

Price

Reviews of ZIC 75W90 gear oil indicate its high quality and reasonable cost. Synthetic products are known for their high prices. However, even in this category, South Korean-made lubricants remain accessible to the buyer.

A liter of synthetic gear oil with the presented viscosity class costs 460-470 rubles. If necessary, you can purchase lubricant in a different container. A 4 liter canister costs about 1500-1550 rubles.

If gear oil is purchased for industrial needs, you can order a 20 or 200 liter barrel. The price of a smaller container will be 6600-6650 rubles. The largest amount of product can be purchased for 56,400-56,500 rubles. This is the average cost. It is not recommended to save on purchasing consumables. This may result in the need for unexpected transmission repairs.

Fake

Reviews of gear oil ZIC 75W90 (synthetic), which can be seen in various sources, indicate the presence of a large number of fakes. Such products are not of high quality. Its use can significantly damage vehicle systems. Therefore, when choosing, you should give preference to offers from trusted sellers.
