Sample preparation of oil products was carried out by ultrasonic treatment. The content of copper in the petrol samples (TNK "Motor 20-w-50," Lukoil "Moto 2 T" Okko «Exol 20w-50 economic», Okko «Exol diesel city 15w-40") was determined by atomic absorption and atomic emission with inductively coupled plasma spectroscopy using copper acetylacetonate as a standard sample. The data were systematized and tabulated. Comparison of the results obtained by the two independent methods was conducted by Fisher's and Student's criterions. It was shown that the results are of uniform precision, the difference is insignificant and could be justified by random dispersion. The detection limit of copper by atomic absorption spectrometry was lower than it was reported before.
