I've never said it was certain to damage an engine and the fact you can get away with it has definitely led to it being perpetuated as a viable solution. But my point is the opportunity for damage is too great with modern engines and most especially for the mechanically inexperienced. You've done it with no problems and continue to do so, and that's fine. Just because you jump off a cliff doesn't mean I have to, and others should in all fairness be advised that their leap from the same precipice may not end up in a happy place.

That's the simplest answer yet: To make a buck off any rube who doesn't know any better. The additive and pour-a-fix aisle? Come on!

Seriously, as mentioned in the previous post I will post scans or links to supporting info. In the meantime we should agree that we disagree on this topic, and that it would be prudent for those interested in an engine flush to do additional research to better suit their needs.
