The article presents the results of a study of the relative dielectric constant and the dielectric loss tangent, the kinematic viscosity of engine oil. The samples of Eni i-Sint MS 5W-30, Elf Evolution 900 SXR 5W-40, Lukoil Lux 10W-40 SL/CF engine oils were used as the object of research. The measuring capacitor with an open area of space has been developed and manufactured. As a result of operation, the kinematic viscosity changed by 10,1 – 21,9 %, the relative dielectric constant increased by

5,9 – 16,7 %, the dielectric loss tangent decreased by 23,7 – 45,3 %. The recommendations obtained were used to implement a dielectric method for diagnosing the
condition of engine oil.

Key words
