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.Many petroleum oils contain surfactants (SF) -additives that improve their performance properties: colloidal stability against separation, chemical stability against oxidation, lubricity, detergent, anticorrosion, demulsifying, and antifoaming properties [1,2].In high enough concentrations, these additives form micellar solutions. The formation and properties of these solutions, the reaction of additives of different types in them and consequently, the effectiveness of the additives are described by the laws of colloid chemistry, physical chemistry, and physics [3,4]. These laws are frequently used in selecting and increasing the effectiveness of additives to lube oils and fuels, which in turn allows reducing consumption of power and the most important petroleum products in modern industry [5,6].Selection of the base oil -the bases in production of commercial lube oil -is determined by both the required functional properties of the oil and the economic indexes of its production and use. Petroleum base oils are the most high-volume. Additives are incorporated in them to enhance certain performance properties [7,8].One method of selecting additives for lube oils is to apply the principles of nanotechnology, to wit, to create a stable structure (dispersion) of colloidal formations (CF) of nano dimensions in commercial oils. Nanosystems, according to the classification used in colloid chemistry, are ultradisperse colloidal systems with a particle size falling in the range of 1 to 100 nm [9][10][11].
