There are a number of different "red" or "orange" ethylene glycol based antifreeze products on the market, DexCool being just one. Each is a different formulation but basically similar in content.
If you are that concerned about which is preferable, go with the traditional green glycol. It really doesn't matter - neither will destroy a PROPERLY maintained engine which has not been overheated.
If you routinely change the antifreeze, any off-the-shelf brand, REGARDLESS OF COLOR, will not destroy an engine - I get sick of some people blowing some complaint into much more than it really is and scaring people about something which is not a problem unless you are careless about the engine in the first place.
Any Class Action suit is just a series of allegations and if you more thoroughly researched the case, one would logically conclude there is sufficient evidence that many of these complainants overheated or otherwise mis-treated their engines such that definitive linking of engine problems to any specific antifreeze is dubious.
If an engine mfg claims they will not honor a warranty unless you use a certain antifreeze, it is a no-brainer what you should use.
If your mfg makes no such stipulation, just make sure you thoroughly flush the old before replacing it with a different colored antifreeze as some do not mix well.
