Contemplating running an engine flush through my 3BII with 330,000 kms (~200,000 miles). To flush or not to flush is a debate that can go on forever, but my goal is to hear from any of you who have actually done it on the 3B and can speak the the results (or detriments). I don't want to wake the sleeping sludge giant unless there's no substantial risks!
