Emery, my fleet of vehicles contains more diesel power than gas power. I was just considering the ELC for my gmc as a way of reducing shop inventory. I'm not looking to start up any arguments on this, and your comments are valued. I will most likely continue to use the basic green variety of coolant in my GMC. For my diesels, i am looking for cavitation protection as well as

>> From my little bit of research, i found that not all of the OAT type coolants are created equally. Cummins have produced several tech documents that contradict the info in the link you provided. Apparently ( i am not an expert on this) Cummins was having gasket and seal problems with the early versions of the OAT coolants and created a new spec that carries their "Cummins 14603" certification. I have read that the ELC coolants carrying the 14603 spec are much safer, and we all know that everything we read on the web is 100% true.

Apparently the designers of my engine (International) recommend using the Cummins spec coolants and not to use the G-05 in the commercial version of the engine.

I will probably convert all my vehicles to this same coolant so i only need to keep one coolant on hand. It reduces risk of mixing the wrong coolants.
