I think that you have to be meticulous about engine oil selection and oil change intervals with any small displacement turbo engine. Between the close tolerances of the turbo moving parts and the additional stresses placed on the engine itself, you are begging for a headache if you become casual about engine maintenance. I have owned just one turbocharged vehicle so far, equipped with a twin-turbo V6, and treated it to full synthetic oil changes every 3,500 miles.
