I really don't think that you should be comparing data on diesel engines with the gasoline engine used in
GMC motorhomes.
You can do what you want but I will stick to my current antifreeze.

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.
