The present work aims at deepening the phenomenon of oil consumption, paying particular attention to the study of oil consumption contribution deriving from turbocharger. In order to evaluate the quantity of oil that leaks from turbocharger oil seals, it was necessary to design a turbocharger lubricating oil system that is totally independent from the main lubricating circuit. The oil consumption from both turbocharger and engine was measured with gravimetric method. A Mercedes OM364LA medium duty Diesel engine was run at maximum power output for more than 300 hours. Different lubricating oils were alternated in order to evaluate the influence of some lubricating oil parameters on oil consumption, while a reference oil was tested at different times to estimate the oil consumption trend during life for both engine and turbocharger.
