FIELD: technology for controlling quality of motor oils using optical means, in particular, detection of additives in motor oils.
SUBSTANCE: method includes taking a sample, measuring optical density in absorption bands 1604 and 2000 cm-1 during spectrophotometry and following calculation of additive concentration using an experimentally derived formula.
EFFECT: expanded nomenclature of motor oil additives detectable by infrared spectroscopy, and also, possible identification of Detersol-140 only and determining of its amount only, as opposed to total content of all additives present in motor oil.
