| dc.description.abstract | Study has chemical and physical properties of a sample of use multi-grade engine oils for gasoline engines at different distances 0, 3000, 4000, 5000 km. The results showed a decrease in the total base number, and chemical additives, viscosity at 40,100 C and flash point. The results showed also an increase in sulphated ash and density. Physicochemical properties of two samples of multi-grade gasoline engine oils, were characterized before and after 5000 kilometers of operation. Results of used engine oils indicated a decrease in Total Base Number (TBN) a percentage 62.8, 25, 65%, element additives 3, 12%, 119, 25.9 viscosity at 100 C 16.48,13.28%. Presence of Oxidative reaction has been configured by FTIR analyzed. | en_US |
