Abstract

The presented paper reveals the possibilities of the implementation of a methodology for evaluating energy savings, at changing the engine oil of different road vehicles. The purpose of the developed methodology is to provide an opportunity to evaluate the energy consumption before and after changing the engine oil of the vehicle. The conditions, the practical procedures and the mechanism for evaluating the energy savings after changing engine oils of vehicles are defined. Changing the engine oil of the car covers the replacement of the old oil with a new one within the maximum mileage determined by the manufacturer. The results of the application of the methodology for certain categories of cars allow an easy process of monitoring and verification. And finally, a computational example is considered, proving that the methodology gives correct results for the evaluation of energy savings, after the replacement of the engine oil of the vehicle.
