- In this paper, the results of researches on lubricity and content analysis of the personal car’s engine oil are presented. The measurements of lubricity are made on the T02-U four-ball tester. The content analysis is made on the Spectroil Q100 spectrometer, which makes it available to measure the amount of 24 chemical elements. Due to this analysis, technical condition of the engine is possible to estimate. Tested oil is Shell Helix AV-L, which was exploited in the personal car, Volkswagen Touran, equipped with the turbo charged diesel engine, with the capacity of 2.0 litres. The samples for oil ageing characteristics were taken from the engine in the intervals approx. 3500 km. This research was performed as a result of the other studies on the dynamic viscosity characteristics. In the viscosity researches for this oil, was shown, that in the first period of the exploitation time, the viscosity decreases significantly. Detailed research on the additives and wear products content, as well as a lubricity characteristic, defines the reason of such a significant decrease of the oil properties. This paper is a part of a wider research on the oil ageing characteristics. It will support development to the new mathematical model of the lubricating oil viscosity changes during the exploitation time of the engine
