Saw this posted on Reddit, the poster referenced a VW patent that showed that DI buildups could be removed if a warmed engine was held at 3000 RPM for at least 20 minutes. Idea was that if the intake valves were allowed to get warm enough for long enough the buildup would be ingested into engine and burned away. Other aspects of the VW patent were suggesting that if engine oil contained enough carbon dissolving solvents the DI buildup might not be an issue.
With modern cars trying to keep revs so low with either 8 or 10 speed transmissions or CVT, the average car spends very little time at 3k RPM and it would be only the BITOG type that would force this routine onto their car for the possible burn off of DI gunk.
What say you?
