An object of the paper are test results of the lube oil consumption in reference to two versions of standard and novel pistons worked out within the framework of the project of developmental No. O R00 0052 05 under the title "The elaboration of the modern technology of composite materials of the novel generation to uses on the pistons of combustion engines to military uses". The project was coordinated by Institute of Aviation; a project manager was Antoni Jankowski. Unique properties, which are characterized by worked out novel material, mainly high hardness and strength, the low hysteresis and coefficient of thermal expansion ....create many novel opportunities. As one of essential evaluation criteria of the novel piston, is lube oil consumption what is the object of the paper. The researches of the pistons were performed in WOLA S12-U engine. Novel solution of the pistons lets on the optimization of the shape of the piston and decreasing of the clearances between piston and cylinder. This causes decreasing of the lube oil consumption, decreasing of blowthroughs to the crank case, decreasing of the noise level and the vibration and the emission level of harmful components of exhaust gases; the improvement of the durability and dependability of the work of the engine and the pistons; increasing of mechanical loads , the pressure increasing combustion , and to the same opportunities increasing of the engine power and the BSFC decreasing.
