This video shows a broken turbo propeller from a Subaru. The vehicle came in for heavy oil consumption and loss of power. Turned out the propeller had broken completely off and lodged in the exhaust pipe/port. A new turbo assembly restored all performance. Most likely, this failure was due to neglected oil change maintenance allowing a restricted oil flow/supply–i.e. the pipe stopped up due to excessive carbon & sludge in the oil. In our experience, turbo motors generally require more frequent oil services and benefit from full synthetic products.
