TSP-15k oil is a popular transmission fluid actively used for transport. Its production history dates back to Soviet times, and quality criteria, rating, recognition and prevalence have not decreased to this day. Its production began at the Kama Automobile Plant with the purpose of improving the operation of KamAZ transmission units, however, today this lubricant is produced by different manufacturers, and the scope of its use has become much wider. In this article we will study the composition and its purpose and possible areas of application, we will talk about the most famous manufacturers of the product, analogues of foreign-made goods.
Gear oil TSP-15 is made from sulfur-containing petroleum product.
Oil composition
Transmission oil TSP-15 is classified as a mineral lubricant product. The product manufacturing process is based on refining, separating and processing petroleum with a huge capacity of sulfur-containing ingredients. As a result of processing, a lubricant is obtained based on residual substances with distillate impurities. The main active ingredient of the oil is sulfur, which increases the antifriction characteristics of the product, which significantly affects its ability to counteract the negative effects of the friction process, which is characteristic of transmission parts. In addition, component additives are added to the oil to improve the quality of the product and increase anti-corrosion and anti-foaming properties.
Specifications
TSP gear oil is manufactured in accordance with GOST 23652–79, according to SAE it is marked 80W-90, classified as a product category TM-3 and identified by the code TM-3–18. The lubricant has the following basic technological characteristics:
- According to production technology, when operating temperature one hundred degrees Celsius is fifteen units, while the variable viscosity of TSP-15k oil at temperature conditions at minus twenty degrees it should fluctuate between up to seventy-five points.
- The density of TSP-15k oil does not exceed nine hundred and ten units.
- The operating temperature range varies from twenty degrees minus to one hundred and thirty degrees plus. In this case, the lubricant hardens at a temperature no higher than twenty degrees below zero, and the temperature criteria for ignition are no less than two hundred and forty degrees.
- The scuffing coefficient, according to production standards, is no less than five hundred and forty units, the tendency to foam does not exceed three hundred in operating condition.
- The mass fraction of water should not be determined, only traces of it in the composition are possible, and mechanical impurities, according to the standard, do not exceed a hundredth of a percent.
TSP-15k, according to technical criteria, can be classified as a multi-purpose lubricant and can be used on vehicles at any time of the year. Oil service life ranges from thirty-six to seventy-two thousand kilometers, depending on external and internal factors.
Scope of application
Initially, the range of use of TSP oil was limited to KamAZ trucks, while it was recommended for use both in the main gear and for filling into transmission units. Today, the sector of application of TSP-15k lubricant is much wider. TSP oil can be used in any type of cargo transport with spiral-bevel and cylindrical gear modifications. It is actively used for lubrication of components and assemblies of agricultural machinery, construction machines and tractors. The use of lubricant is recommended for all types of transport, the technical documentation for which requires filling with TM-3 class liquid.
What's in the name?
TSP-15 oil is classified as an oil with the identifier TM-3. What does its name mean? Based on the technical documentation, the “TSP-15k” marking is interpreted as follows:
- The letter "T" is an abbreviation for the word "transmission".
- The symbol “C” indicates that the product is manufactured from a sulfur-containing petroleum product.
- The letter “P” indicates the presence of additives in the product, which ensure wear resistance of the processed structures and guarantee the quality of the oil.
- The number 15 indicates the viscosity coefficient of the lubricant.
- The symbol “k” stands for vector standardization of products, or, more precisely, the sectoral purpose of the oil for technical units of KamAZ vehicles.
Previously, when there was one plant producing oil in this category, it was simply called TSP-15k. Today it is produced by several large manufacturers lubricants and a lot of small companies. To differentiate your oil from similar products, large factories often the company name is written before the labeling. When choosing an oil, the buyer should first of all be guided by the labeling of the product, which characterizes its technical features, and then by the manufacturer.
Competitors and international recognition
Lukoil is considered the most popular manufacturer of TSP-15k oil today, however, it is not a monopolist in this field of activity. RosNeft is also considered Lukoil's biggest rivals. Gear oil of the TSP-15k category is also produced by many small factories, the most active among which are the Zarechye and Nekton Sea concerns, as well as numerous regional suppliers.
Among other things, TSP-15 oil, according to the API classification, complies with the GL-3 standardization, recognized throughout the world. Lubricants for trucks are produced by foreign manufacturers according to the same standards. The most popular imported analogues of TSP 15 lubricating fluid: Shell, SpiraxEP 90W Mobil, Gear oil EP 90 and others. Availability of analogues on international market speaks of the high competitiveness of domestic TSP liquid and confirms its demand in the industrial sector. Despite the strict control of the foreign market by its manufacturers, TSP-15 is successfully exported abroad and has its own buyer.
Let's sum it up
TSP oil is recognized not only by domestic consumers, but is also ranked among those recognized throughout the world. Its quality characteristics have proven their effective influence on the performance properties of transmission structures, provided that the products are used in the appropriate climatic regions. Priority should be given to oils that are sold at points of sale that have certification documents for the goods sold. This is the only way the buyer can protect himself from purchasing low-quality lubricant products that do not meet GOST standards and, accordingly, the declared characteristics.
5.1. Oil samples are taken according to GOST 2517. The volume of the combined oil sample of each brand is 2 dm 3.5.2. When testing for corrosion on copper plates of TSp-10 grade oil, redness is allowed, including shades from yellow to crimson. The appearance of green, brown-black and steel-gray spots and plaques on the plates is a rejection sign. When testing TSp-14 hyp oil, the presence of foci (spots) of darkening and tarnish on copper plates does not serve as a rejection sign (with a total area of darkening of no more than 50%); Black stains and deposits are not allowed.
Corrosion testing is carried out on plates made of copper grade M1k according to GOST 859 and steel grades 40, 45 or 50 according to GOST 1050.

5.4.2.1. Carrying out the test
Each of the indicators - the increase in viscosity and the mass fraction of sediment - is determined in at least two flasks.
Samples of oxidized oil to determine the mass fraction of sediment and increase in viscosity are taken from different reaction flasks.
