1.8T oil sludgeing..flush or not to flush?

[David]

I've done a 50/50 oil to Marvelous Mystery Oil flush on a really ugly engine (old Chevy 350 with hundreds of thousands of miles with no rebuild and poor maintenance). Drain oil, add 50/50 oil/MMO, run engine for no more than 15 minutes then do another oil change. Worked great.

I always drain 1qt of oil and add 1 qt of MMO to my CGT about a week before changing the oil. Takes a little while, but does a really nice job of cleaning the engine. When I got her new oiklwould be black within 500 miles, not it stays pretty clean through 5000 miles.  if you are worried, take the less agressive approach of just doing MMO before the oil change like I do.
