AB - CHEMMOTOLOGY CHANGE IN COLLOIDAL STABILITY OF USED MOTOR OILS DUE TO CONTAMINATION BY COOLANT UDC 621.892.096-714:547.91 V. A. Artem'ev, D. V. Boykov, and V. L. Lebedeva The colloidal stability of motor oils is determined by a combination of physicochemical properties of the base stock, the additive package, and contaminants [i], in particular the coolant [2-4]. In a number of cases, the entry of coolants (water and antifreeze) into the crankcase has an adverse effect on the operating reliability of internal combustion engines, mainly because of increased sludge and carbon deposit formation, shortened life of oil fil- ters, and acceleration of corrosive mechanical wear of the principal parts of the engine. The adverse effects on service properties are particularly severe for oils that have un- satisfactory hydrolytic stability in storage, for example the oils M-10V 2 and M-10G2 (GOST [All-Union State Standard] 8581-78), which are formulated with an additive that is suscept- ible to hydrolysis. In contrast, the service properties of the oils M-10G2(k) and M-10D(m) (GOST 8581-78) show practically no deterioration during storage under wet conditions [5]. However, experience in the operation of YaMZ diesel engines on these oils has revealed cases in which their colloidal stability decreases, with
