If people want to continue the antifreeze debate in General Chat, fine. But when someone uses a mechanical thread to further their view of this debate or any debate,.... it is not fine. Debate and discussion of such is for Chat, not mechanical threads. Especially when it isn't advice on an OP'* question. These sections are for stating and solving problems. Posts will be pulled and the member notified why.
Dan and I both have extensive reading and discussion about this under our belts, and the "Official Forum Stance" is you should use what the manufacturer recommends. While Dex got all the publicity about this, almost all manufacturers have had the problem. Especially Ford with its extended. The problem is not the coolant. The problem is that type of gasket is prone to rapid degradation when they come into contact with an acidic coolant. All coolants go acidic given time or even other contributing factors, like overheating. Nothing turns Dex brown quicker as I found out myself after an overheat. When coolants are used according to directions and not allowed to acidify, all are safe. Warranties can be voided for using other than stated. And long term use of one creates residue hard to remove with a simple flush. Why risk sludge? So for the Forum'* Admins Staff, we recommend you follow OEM requirements.
