Hybrid drive systems are becoming the dominant drive type in currently manufactured passenger cars. This article presents the results of an analysis of selected heavy metal content in used engine oils collected from car service stations during oil changes. The combustion engine in hybrid systems operates under unusual conditions due to frequent switching on and off. The main aim of the study was to determine the difference in heavy metal content (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sn, and Zn) in 0W16 oils used in hybrid vehicles and conventional gasoline vehicles. Twenty samples of used engine oils collected from passenger cars were analyzed. Heavy metal content was determined using the ICP OES technique after mineralization of the oil samples. The metal content profiles for both engine types were similar. Analyzing the differences in the average content of the elements tested, depending on the engine type, it can be concluded that the total heavy metal con-tent in oils from hybrid systems was 1.462 mg per kilogram of used oil, which was 10% lower than in gasoline engines (1.625 mg/kg). This indicates less oil degradation, which in these conditions allows for longer service life and reduces vehicle operating costs. Reduced oil degradation also means fewer oil changes, lower energy consumption for its production, and reduced waste and energy and resources required for waste oil disposal.
