DRAIN INTERVALS FOR ENGINE OIL-MINERAL, SEMI AND FULL SYNTHETIC LUBRICANTS

Abstract

During the last few years OEMs and more generally all the automotive industry has achieved considerable progress in improving efficiency power unit of internal combustion engines and lowering emissions, while reducing production cost and increasing the drain intervals for minimizing customer maintenance cost. There exists a 100-year-old technological coordination of lubricants and fuels with constructive specialties of motor vehicles and engines. With motor vehicles we have many different regimes of exploitation. That is why vehicles have the most complex demands towards of lubricants and fuels. After introducing the mandatory diagnostics on OBD vehicles we get a huge amount of data, which describes the working conditions. In the next phase of the OBD-II with wide appliance of electronics and specific sensors gives us the possibilities of collecting various data on working conditions. Formed bases of data are kept in the memory of the vehicles or distributed in service or developing centers. In everyday use of vehicles, with flexible service systems, judging from the knowledge base for discovering the problems and to correctly defines the servicing period for drain intervals of the lubricants and all fluids used in the vehicles. It is very important for determination drain intervals of the new lubricants, which formulated with what we call "unconventional base stocks".
