No, it's a result of two things.... One, emissions running a "hot" head as well as a naturally hot turbo. Two, a restrictive PCV system. Combine the two and you've got automotive ateriosclerosis.
Shorter oil change intervals and synthetic will help. But won't do much after the damage is already done.
