Minimizing engine oil consumption of modern engines has become an important issue and there is a need for better understanding associated sources and mechanisms. An innovative method based on the use of radiotracer compounds that are representative of oil distillation interval has been presented in a previous paper. This paper presents a methodology to evaluate and quantify oil consumption sources in a production turbocharged spark ignition engine at different speed and load conditions. A specific experimental set-up was used to measure independently and in real-time contribution of piston ring package, blow-by circuit, and turbocharger on oil consumption. Results show how contribution of each consumption source varies with engine operating conditions.
