Yes, it is an issue in SOME engines. European manufacturers resolved that or do not have that issue in general. Hyundai &Co? Yes.I think that it is a combination of both, but it is predominately discussed in regards to turbo applications, most notably ones with low RPM boost. 1200-4500rpm.
It is confined to small turbo engines, generally below 2.0ltr displacement, mostly around 0.8 to 1.6ltr.
