Yes I know a couple of people that were running on sludge instead of oil. Well I change the oil religiously every 2500-3000 miles. Some of the Evo forum guys say that as long as you always use good full synthetic oil you should never have to do an engine flush. I say it depends on driving conditions, geographical location etc. One last question if you don't mind.I was thinking about using Amsoil engine flush as opposed to Gunk. What do you think?
