Water contamination of motor oils during storage and use in low-temperature conditions cause formation of deposits. These
deposits, which consist of asphaltenes and additives, characterize the colloidal stability of the oils. A decrease in the
concentration of additives worsens the performance properties of the motor oils.

The effect of viscosity additives from the Viscoplex series on the rheological properties of M-10G2k lubricants, developed from Baku base oils, was investigated with consideration of current environmental and sanitary-hygienic
requirements. It was found that the system consisting of a mineral oil and viscosity additives is characterized by non-Newtonian
behavior — at a shear rate of 60–80 sec−1, the character of flow is pseudoplastic — and is distinguished by good starting properties at temperatures from +10 to −20°C.

The performance properties of the initial components and finished product were evaluated during fabrication of models of commercial
lube oils by scattered light correlation spectroscopy. This method allows determining the size and average radius of colloidal
formations and the stability of colloidal solutions against separation. Using the data obtained, changes can be made in the
manufacturing technology and formula of the oils by changing the mixing temperature and parameters of the initial components:
the indexes of the base, the sequence of incorporating the additives, and the concentration and composition of the additives.

Precipitation of sediment caused by external factors — temperature and solvent — is due to the spin nature of the contaminants
formed during use of the oil. These paramagnetic contaminants also lead to aging of oils. Their total elimination restores
the properties of used oil to the level of the base oil, but requires sufficient energy effects.

The possibility of obtaining viscosity additives for petroleum and synthetic oils by synthesizing co-oligomers of allylnaphthenates
with butyl methacrylate and allylnaphthenates with styrene was investigated. The conditions for obtaining co-oligomers with
assigned properties were found. The compounds obtained have improved viscosity-temperature properties and are much more resistant
to thermal effects than industrial viscosity additives.

A new motor oil — AZMOL GARANT M-4042 VT — was developed for two-and four-cycle heavy-duty, heavily loaded diesel engines.
A distinctive feature of this oil is the complex zinc-and barium-containing additives of the dithiophosphate type it contains
— MASMA-1606, which ensured high lubricant and antioxidant properties. The oil was approved for production and use after testing
with positive results. Ukraine specifications were developed for the oil: TU U 23.2-00152365-229:2006.

Detergent-dispersant additives (DD additives) are widely used in modern motor oils. Detergents are ash additives and dispersants
are ashless additives. Some of the most common metal-containing detergents used in the world are metal alkylphenolates, primarily
calcium, barium, and magnesium alkylphenolates, which have a high degree of detergent properties. This is due to the broad
spectrum of operating properties, relative availability of the initial stock, and simplicity of the manufacturning technology.

The results of fast quality control of oils by nonstandard methods are reported. The possibility of developing methods of
determining the basic indexes of oils — the dielectric loss tangent, the base number based on the measured dielectric constant,
and the resistivity — is examined. Motor oils from different manufacturers have different dielectric constants, which allows
identifying the manufacturing company.

A laboratory method was developed for evaluating the performance properties of lube oils used in gas-pumping sets. The correspondence
of the results obtained by this method and the data on the performance of the oils was demonstrated. The method is intended
for fast acceptance control of fresh oils, evaluation of the change in the properties of the oils during use and storage in
warehouses, and for developing new lube oils and detecting counterfeit products.

Research on the chemistry and technology of lubricants is a basic research direction in the scientific school of Professor
N. I. Chernozhukov, created more than 50 years ago. The results of this school’s research have significantly expanded the
ideas concerning the production and use of oils and greases and the effect of the nature of the stock on the relationship
of the composition (colloidal structure) and properties of the commercial products obtained.

The following sequence of processing lube distillates from atmospheric-vacuum tubestill (AVT) units are most commonly used
for production of base oils: selective treatment — dewaxing — hydrotreating. As a result of hydrotreating, sulfur and tars
are removed from the intermediate product, the carbon residue decreases, and the color improves. This final stage frequently
determines the quality of base oils. However, its role in obtaining the required quality is usually small, since the basic
indexes are formed in the preceding stages.

The extensive utilization of deposits of highly viscous crude oils is stimulating a wider investigation of the physicochemical
processes involving macromolecular resins and asphaltenes (RA). The reliability of operation of turbolines in pumping crude
oils with a high solid point is determined to a significant degree by the possibility of controlling the flow of liquid colloidal
systems whose disperse phase is primarily represented by asphaltenes. However, there is no sufficiently complete information
on cross-linking mechanisms involving molecules of RA and the degree of the effect of the structures formed on the rheology
of the liquids for such control. We used viscometry to investigate the characteristics of association and dispersion of RA
in relatively simple model liquid media. The effect of the concentration composition of liquid media were previously primarily
investigated in such studies [1 – 3]. The step for changing the temperature was too high: 10°C and higher, to determine any
thermal characteristics of viscous flow.
