In this paper, the life expectancy of the engine oil in 70 diesel engines installed in super heavy vehicles (the E6-350 ECONODYNE 4VH model) has been estimated using oil analysis. The method which used, was to change the used oil based on oil operating hours, odometer and taking samples. Then, the oil sample was sent to a laboratory for the analysis. In order to be able to determine the overall condition of the engine, we had to study various parameters, such as the viscosity, the base number, the acid number, the type and the amount of the engine wear in the same condition of the engine model, the oil consumption and the operating conditions. Therefore, the oil life expectancy would be determined. If the number of samples increases, then the value of errors will be reduced. Results would merely be based on the number of samples.
