That was a interesting read. I am not too worried about an extra 3%(6.6gr)of dust in my engine. The report states that the dust goes into the oil, so change you oil at recommemed intervals or more. But the underlining moral is sometimes flashy isn't better, but sometimes it looks cool. You should see the stuff that we breathe in, dead skin, dust mite poop,etc. Everyone would wear a hepa filter mask!! Thanks for the link.
