A method for predicting the tribological properties of lubricants was based on the estn. of limiting pressure of seizure and limiting load of the wear for the lubricant consisting of a corm packages of antiseizure and antiwear additives (1-4% by mass, 3-8% by mass, resp.) and mineral oil. According the adopted procedure, samples of lubricants of different compn. were prepd. The limiting pressure and load were detd. exptl. The coeffs. of the regression equations were calcd.
