Yes -- this is true. Although my experiences with turbocharged fours is thus:
I owned a 2009 Mini Cooper S, with the turbocharged 1.6 BMW engine. As I understand it, oil consumption was very high with these turbo engines. The timing chain tensioner was also regulated by the engine's oil pressure; if the engine was low on oil, the timing chain would get loose and rattle. Oil consumption was such that every few months, I would start to get a rattle on start-up, and that would be my signal that I needed to top off the oil (well before the light came on). Forgive me if I'm getting any of this wrong; this is how it was explained to me by the techs at New Country Motors in CT.
I also had a 1986 Porsche 951. That car was very maintenance-intensive, but that probably had more to do with my novice tuning attempts than anything relating to build quality.
