    All problems associated with running a normally aspirated engine dry also apply here but there are additional problems due to the turbo's dependence on oil. The bearing in a turbo is a normally a plain bearing. As with main crank and cam journals, lack of oil can cause the bearing to seize almost immediately. In less exteme cases excessive wear can occurr which, in turn, can lead to either compressor or impeller vanes fouling the turbo housing. This is not good. Finally even a low or infrequently serviced oil supply can cause a rapid build up of carbon deposits. The resulting sludge can cause blockages which results in problems as above. Frequent servicing and visual inspection of the oil will keep a turbo whistling happily.

    • That said, newer turbo engines are usually better about this than those of 15-20 years ago.
