I bought four jugs of the O'reilly's extended life antifreeze. Says it is good for all makes and models and can be mixed with any cooler/type of antifreeze. Nowhere on the containers does it indicate HOAT or G-05. It does indicate to be EG and not PG. Has anyone used this stuff or can tell me if it is compatible with what Cummins recommends? I do plan on performing several flushes to remove as much of the old stuff as possible before going in with the new. I couldn't seem to find any information on this site discussing this coolant. TIA
