Manufacturer
Gear oil (synthetics) ZIC 75W90 (specifications, reviews, photos are presented below) belongs to the category of high-tech products of the new generation. It is produced by the South Korean manufacturer SK Corporation. This brand is known as one of the major suppliers of lubricants for enterprises in Asian engineering.
Almost all cars that go off the assembly lines in China, Japan, and Vietnam are supplied with SK Corporation oils. In the manufacture of its compositions, the South Korean company takes into account the highest requirements of modern engineering. Due to this, its lubricating compounds fully comply with the technological, environmental requirements of the world community.
The products of the presented brand are in demand in our country. This is due to the acceptable cost and high quality of the compounds. The presented means reliably protect mechanisms and components from premature wear.
general characteristics
Transmission oil ZIC 75W90 (synthetics), the characteristics of which will be presented later, has a number of features. This product is manufactured using the latest scientific developments. Thanks to its special formula, grease significantly improves the performance of gearboxes.
The presented product is intended for manual gearboxes. It is also used for truck bridges, cars. Gear oil of this category is suitable for construction equipment.
This product reliably protects transmission parts from scoring, mechanical damage. This is a fairly universal tool. It can be used in various conditions. When choosing a lubricant, follow the manufacturer's recommendations.
Property Basis
Using a high-quality base, ZIC 75W90 gear oil is manufactured . Semi-synthetics and synthetics are today the most popular substances from which consumables for gearboxes are made. The most popular are synthetic lubricants. They are made on the basis of a special, high-quality oil. It is created using Yubase technology.
The base of the oil also includes PAO components and balanced additives. Synthetic oils contribute to the rapid distribution of funds within the system. They cover with a thin layer all the details. This allows the movable elements to slide well.
The composition of semi-synthetic products includes mineral oils. Such compositions are suitable for medium loaded conditions. Replacement of such substances is carried out earlier than synthetic oils. But their cost will be slightly lower. A synthetic product for South Korean-made manual gearboxes provides reliable transmission protection even at high, constant loads.
Specifications
Considering reviews of ZIC 75W90 gear oil (semi-synthetic, synthetic), it should be noted the high popularity of the product of the GFT series. Its technical characteristics indicate a high reliability of the product.
The density of the composition at 15 ° C is 0.86 g / cm³. At the same time, the kinematic viscosity at 100 ° C is 14.1 mm² / s. Product quality is confirmed by a high flash point. The oil ignites when it reaches 212º. When the transmission of the car, such temperatures are almost unattainable.
Oil begins to lose its fluidity at a temperature of -47.5º. 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 say that the data provided by the manufacturer are fully true.
Lubricity
Considering the characteristics, reviews about ZIC 75W90 transmission oil (synthetics), which are left by specialists in the field of lubricants, it is necessary to note the exact compliance with the standards of the presented means.
The South Korean manufacturer's manual gearbox oil is manufactured in accordance with GL-4, GL-5 standards. These guidelines apply to the production of all transmission fluids.
Compliance with the presented compositions indicates the possibility of using oil in medium and high-loaded systems. The composition includes a sufficient number of additives that can reliably protect the mechanism from adverse effects. Even with increasing temperature, speeds of rotation of the mechanisms, the oil will provide a good glide of the rubbing metal parts.
Additives
Reviews of gear oil ZIC 75W90 indicate the high reliability of the presented funds. The manufacturer adds a balanced additive package to the base. If before that another oil was 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 composition of the oils of the South Korean brand includes only new, high-quality components. They have several effects on the system. Anti-seize ingredients provide a good glide mechanism. The oil film does not tear, dry surfaces do not appear.
Also included are antioxidant additives. They prevent the development of corrosion and oxidation. Oil can be used for a long time. Its additional filling or complete replacement may be required much less frequently.
Cost
Reviews of gear oil ZIC 75W90 speak of its high quality and reasonable cost. Synthetic products are known for their high price. However, even in this category, South Korean lubricants are still available to customers.
A liter of synthetic gear oil with the presented viscosity class costs 460-470 rubles. If necessary, you can purchase lubricant in a different capacity. A 4 liter canister costs about 1,500-1550 rubles.
If transmission oil is purchased for industrial purposes, you can order a barrel of 20 or 200 liters. The price of a smaller container will be 6600-6650 rubles. The largest amount of funds can be purchased for 56400-56500 rubles. This is the average cost. Saving on the purchase of consumables is not recommended. This may lead to the need for an unexpected transmission repair.
Fake
Reviews of transmission oil ZIC 75W90 (synthetics), 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 harm car systems. Therefore, when choosing, you should give preference to the proposals of trusted sellers.
Forgery is distinguished by sloppy adhesions on cans. When choosing, you must carefully inspect the container. It should not have defects, hieroglyphs, extraneous inscriptions.
The color of the canister should be dark red. There should not be any stains on the material. The ring should not be pressed firmly against the cover. There should be a gap of several millimeters. The cover must not be open.
